Re: [Amel Yacht Owners] Shore power plug questions.

Good afternoon Alan,

Very interesting…

I had no clue the boat limit was 16 amp…
I thought it was 32 amp (because of the 32 amp breaker on the 220 volt panel in the galley).
Why putting a 32 amp if the system only can take 16 ??? (asking myself)

3 years ago, I run all 3 air condition, battery charger and used outlets for my computer, no clue how many amp I draw…

Good thing I installed the Blue Sea AC meter… which will allow me to be careful.

Ok good to know the short cable wouldn’t be a problem for 16 Amp.

Well thanks again for your information which kind of made me thinking…

Sincerely, Alexandre

Bonjour Alexandre,
The 16 / 32A adaptor is just for
convenience (and strictly not legal in most places) to allow
you to connect to a 32A socket if a 16A is not
available.You should not draw more than 16A from
this outlet.
You are
right that would be more logical, but then the boat wiring
would also need to be much bigger to take 32A
draw.
As it is the
boat system is designed for 16A shore power and you should
not exceed that.
Everything is a compromise...you
always need to be aware of how much current you are drawing
so the capacity of the wiring, breakers and shiore
connections are not exceeded.
The Schuko plug is variously 10, 12,
16A depending on who made it and in which country, but with
such a short length of cable it shouldn't be a problem
up to 16A.
The frig
and freezer run from the 24VDC battery supply, so if that is
all you are running, you need the small battery charger
running to keep the batteries charged and that is only about
4A on the 220V circuit when it is putting out max current to
the batteries, which it won't if the batteries are fully
charged...so, no problem.

Good afternoon
Alan, 

Thanks very much for your
reply. 

Just to make sure, even
thought it says 16 amp on the plug, it is ok to connect them
to a 32 amp connection and obtain up to 32 amp from
them? 
The plug will
take it ??? 

To me, it would
have been more logical to have: 
Power cable coming from the boat terminated with a
32 Amp (and not 16)
Then the extension has 32 Amp on each
side. 
Then have an
adapter that would reduce to a smaller 16 Amp shore
plug. 


So you would actually connect
your vessel (in a ship yard) to the Schuko (black 2 pin) and
be able to run freezer, fridge, etc.? up to 16 amp? Or would
you limit yourself to much less? The cable seem so
small… 


Enjoy Noumea! Thanks for your
reply, Alexandre

Hi Joel,

On Kristy, there was no breaker for that pump.  I installed one as per installation instructions from Climma on the existing 220 panel in the galley (an unused breaker)

Re: [Amel Yacht Owners] Shore power plug questions.

Bonjour Alexandre,

The 16 / 32A adaptor is just for convenience (and strictly not legal in most places) to allow you to connect to a 32A socket if a 16A is not available.
You should not draw more than 16A from this outlet.

You are right that would be more logical, but then the boat wiring would also need to be much bigger to take 32A draw.

As it is the boat system is designed for 16A shore power and you should not exceed that.

Everything is a compromise...you always need to be aware of how much current you are drawing so the capacity of the wiring, breakers and shiore connections are not exceeded.

The Schuko plug is variously 10, 12, 16A depending on who made it and in which country, but with such a short length of cable it shouldn't be a problem up to 16A.

The frig and freezer run from the 24VDC battery supply, so if that is all you are running, you need the small battery charger running to keep the batteries charged and that is only about 4A on the 220V circuit when it is putting out max current to the batteries, which it won't if the batteries are fully charged...so, no problem.

Good afternoon Alan, 

Thanks very much for your reply. 

Just to make sure, even thought it says 16 amp on the plug, it is ok to connect them to a 32 amp connection and obtain up to 32 amp from them? 
The plug will take it ??? 

To me, it would have been more logical to have: 
Power cable coming from the boat terminated with a 32 Amp (and not 16)
Then the extension has 32 Amp on each side. 
Then have an adapter that would reduce to a smaller 16 Amp shore plug. 


So you would actually connect your vessel (in a ship yard) to the Schuko (black 2 pin) and be able to run freezer, fridge, etc.? up to 16 amp? Or would you limit yourself to much less? The cable seem so small… 


Enjoy Noumea! Thanks for your reply, Alexandre

Hi Alexandre,
Apart from the 4 pin red plugs, we
have the same set of plugs and cables plus a few more for
South Pacific connections.
The 16A and 32A plugs are different
sizes. The boat system is 16A, the cable that goes from 16A
socket to 32A plug is so you can plug into a 32A socket on a
dock...some docks eg Taina Marina, Papeete, in some places
have only 32A sockets.
The black 2 pin plug connected to
the 16A socket, allows you to connect to normal European
power outlets, eg in the yard at Nouvile Plaisance in
Noumea, where we are now.
The red ones...I don't know what
they are for, but they look like they haven't been used
in a long while !
Hoep
this helps

Re: [Amel Yacht Owners] Shore power plug questions.

Alan Leslie
 

Hi Alexandre,

Apart from the 4 pin red plugs, we have the same set of plugs and cables plus a few more for South Pacific connections.

The 16A and 32A plugs are different sizes. The boat system is 16A, the cable that goes from 16A socket to 32A plug is so you can plug into a 32A socket on a dock...some docks eg Taina Marina, Papeete, in some places have only 32A sockets.

The black 2 pin plug connected to the 16A socket, allows you to connect to normal European power outlets, eg in the yard at Nouvile Plaisance in Noumea, where we are now.

The red ones...I don't know what they are for, but they look like they haven't been used in a long while !

Hoep this helps

Cheers

On the Super Maramu,. Hull # 400+, what/where is the protection/circuit breaker for the salt/raw water pump for the air conditioners? I think this was discussed but my search came up with nothing.

Hello Martin. The red on your Amel 54 is,  unless it has been modified/painted, gel coat. Red is second only to black for its tendency to heavily oxidize when exposed to the sun. It can be compounded and then polished to bring it back to glossy, but I would not attempt to do this by hand. If you are not proficient with the use of a electric polishing machine, it might be a good idea to watch an expert do this the first time in order to learn how to make it better without doing any damage or removing too much gel coat.

 

Good luck with this project and with your voyaging plans.

 

Have fun with your Amel!

Hi friends,

 

My AMEL 54 dates from 2010. The red line on the top edge of the hull became matt over the years. Any ideas how to make it nice and shiny again? Polish? But it is obviouslly no gelcoat. Polish anyhow?

 

Welcome your hints.

Thanks for the reply Mike,

Do you know if the 110-220 Volt transformer is for sure an 'isolation transformer?

Sincerely Alexandre

Hi,
My understanding is that if an
'isolation transformer' at the first point of entry
to the boat then a galvanic isolator us not required as
there is no potentional earth return circuit between the
boat and shore power.
http://www.bcet.co.uk/marine-isolation-transformers.html
it is the best option for preventing
galvanic corrosion but also the most expensive and
heaviest.

Hi
again Alex.I've
been told that the 110-220V transformer is an isolated
transformer and thus doesn't need to be protected by a
galvanic isolator.  Maybe someone can expound on that
theory.  If it's true, your 110VAC shore power may
already be protected????Kent

Good
morning Kent,



Our vessel are similar.



And if you look at all the pictures I posted, especially
Part 2, you will see I trace the wires to the automatic
switch above the genset as this is where I remember Olivier
mentioned to connect the Galvanic Isolator.



Therefore, that box “intimidates” me… and I felt
logical to connect the Galvanic Isolator to the very first
connection (which is the box on top of the forward
bulkhead).

If I did not had that box, then the first connection would
have been the automatic switch above the genset.



As Derick mentioned and was thinking the other night:
currently the 110 shore power is not protected.

Not a problem as I don’t use the 100 volt power.

By Connecting its earth to the domino, it will be.

And the Big cubical white transformer will be after and not
before the Galvanic Isolator.



Would love to hear back from Olivier on my set-up



Alexandre

Hi Alex,Your #289 is fairly

close to my #243.

I'm not on the

boat, so writing this from memory.  If I've left

something out or am still clueless about something,
please

chime in.

 If Nikimat is like

Kristy, the 110AC shore power will go directly to a box
on

the forward bulkhead, up against the cockpit floor.  It

terminates at a 110AC 30A breaker there.  From the
breaker,

it goes to your 110->220 AC transformer.  On Kristy
the

transformer is a cubical box on the forward end of the
shelf

above the generator.The converted 220AC

power output (which will be the same frequency as the
input,

60Hz) then goes back to the box on the bulkhead to a
female

plug marked "220 via the transformer" (sorry,

it's inFrench and I can't remember it exactly).
 To

use 110 shore power, you have to insert the male plug in

this receptacle. (For 220 shore power it has to be
plugged

into the other receptacle on the front of that box
marked

2"20AC Sur Le Quai".From either receptacle,

it then goes to the automatic switch which chooses
generator

power over shore power.  This is above the generator. I

don't remember how it is marked.  There is another
box

near there marked 220AC that has the relays for the Air

Conditioners that turn on the 220AC raw water pump which

cools all three A/C units.From that automatic

switch, all 220AC power goes to the 220 breakers in the

galley.

If you have a 220

inverter, power goes from it to the 220 panel
receptacles

and microwave breakers.  I think others have a little

different set up with the inverter.

In a post a year or so

ago, Olivier suggested that you could cover both 220AC
and

110AC shore power by putting the galvanic isolator in
the

ground wire that goes from the box on the forward
bulkhead

in the engine room to the automatic switch above the

generator.  My understanding is that the 110->220

transformer is an "isolation transformer", and

having it between the shore power and the galvanic
isolator

is not a problem.  The only other item that is between

shore power and the galvanic isolator with this placement
is

the 110 breaker in the box on the forward engine room

bulkhead.

Hop that

Good afternoon Derick,







Thanks for the compliment and also to pay attention to
the

details!!!







You are totally correct, currently only the 220 volt is

connected.



Electricity is my weakest subject, so building confidence!










I was just thinking last night the same thing you
mentioned!





The 110 Volt earth should fit inside the electric

“domino”.







My 110 volt doesn’t have any shore plug… I need to
open

the box and look at what color cable I have and see
where

they go.







Do you have both shore power?



If so what good options could be good to have?







I assume the 30 A 125 Volt?



http://www.frugal-mariner.com/images/img0565.png







Does any of you have other plug for European, South

American, etc. Marinas?







Once I take the pictures, i will make a post just for
it.







Thanks again, sincerely, Alexandre

Alexandre,



Nicely illustrated, as always.



 Thank you for the instructive pictures!



I note that the way you have hooked



up the galvanic isolator, only the 230V shore line is



isolated.  The 110V shore line is not (yet) protected.



 You can protect the 110V shore line using the same



isolator by hooking it up similarly simultaneously.



 Disconnect the 110V ground from the common post in
the



box, and connect it to the input side of the galvanic



isolator using the same connection point as the 230V

shore



ground and you have done it!  (I.e. Change your 2-wire



connector to a three-wire connector.)



That way you are protected no matter



which shore line you use!

Autopilot problem

Paul Osterberg
 

The other day we change our old Autohelm type 300 course computer to a Raymarine S3G, still keeping the old Autohelm ST 7000 control unit. It all started very well it kept the course very straight and had no problem even though the wave was rather high and wind only moderate, except that the compass reading was almost 180 degree wrong. 

Then after a while the Autopilot goes totally berserk, steering away totally uncontrolled, we put it in stand by and then Auto again it worked fine for ca 24 h, then berserk again.

When later at harbor we notice that in Stand by mode the compass suddenly gave reading all over the place, it change every second all over the 360 degree, not strange that it does not steer well.

 Does anyone have experienced similar behavior? Anyone know the remedy for such behavior?

Paul on S/Y Kerpa SM#259 currently in Gibraltar

If you could please confirm this is the Original plug at the end of the 220 Volt shore cable.

If you could look at the extension (when dock bow first) and how it needs a smaller extension, my question/concern is that is says 16 AMP on the plug, please look at the pictures and let me know.


If you have time, I put a 2nd page with 4 questions regarding additional plugs I have on the boat:

Hi,
My understanding is that if an 'isolation transformer' at the first point of entry to the boat then a galvanic isolator us not required as there is no potentional earth return circuit between the boat and shore power.
http://www.bcet.co.uk/marine-isolation-transformers.html
it is the best option for preventing galvanic corrosion but also the most expensive and heaviest.

Hi again Alex.I've been told that the 110-220V transformer is an isolated transformer and thus doesn't need to be protected by a galvanic isolator.  Maybe someone can expound on that theory.  If it's true, your 110VAC shore power may already be protected????Kent

Good morning Kent,



Our vessel are similar.



And if you look at all the pictures I posted, especially Part 2, you will see I trace the wires to the automatic switch above the genset as this is where I remember Olivier mentioned to connect the Galvanic Isolator.



Therefore, that box “intimidates” me… and I felt logical to connect the Galvanic Isolator to the very first connection (which is the box on top of the forward bulkhead).

If I did not had that box, then the first connection would have been the automatic switch above the genset.



As Derick mentioned and was thinking the other night: currently the 110 shore power is not protected.

Not a problem as I don’t use the 100 volt power.

By Connecting its earth to the domino, it will be.

And the Big cubical white transformer will be after and not before the Galvanic Isolator.



Would love to hear back from Olivier on my set-up



Alexandre

Hi Alex,Your #289 is fairly

close to my #243.

I'm not on the

boat, so writing this from memory.  If I've left

something out or am still clueless about something, please

chime in.

 If Nikimat is like

Kristy, the 110AC shore power will go directly to a box on

the forward bulkhead, up against the cockpit floor.  It

terminates at a 110AC 30A breaker there.  From the breaker,

it goes to your 110->220 AC transformer.  On Kristy the

transformer is a cubical box on the forward end of the shelf

above the generator.The converted 220AC

power output (which will be the same frequency as the input,

60Hz) then goes back to the box on the bulkhead to a female

plug marked "220 via the transformer" (sorry,

it's inFrench and I can't remember it exactly).  To

use 110 shore power, you have to insert the male plug in

this receptacle. (For 220 shore power it has to be plugged

into the other receptacle on the front of that box marked

2"20AC Sur Le Quai".From either receptacle,

it then goes to the automatic switch which chooses generator

power over shore power.  This is above the generator. I

don't remember how it is marked.  There is another box

near there marked 220AC that has the relays for the Air

Conditioners that turn on the 220AC raw water pump which

cools all three A/C units.From that automatic

switch, all 220AC power goes to the 220 breakers in the

galley.

If you have a 220

inverter, power goes from it to the 220 panel receptacles

and microwave breakers.  I think others have a little

different set up with the inverter.

In a post a year or so

ago, Olivier suggested that you could cover both 220AC and

110AC shore power by putting the galvanic isolator in the

ground wire that goes from the box on the forward bulkhead

in the engine room to the automatic switch above the

generator.  My understanding is that the 110->220

transformer is an "isolation transformer", and

having it between the shore power and the galvanic isolator

is not a problem.  The only other item that is between

shore power and the galvanic isolator with this placement is

the 110 breaker in the box on the forward engine room

bulkhead.

Hop that

Good afternoon Derick,







Thanks for the compliment and also to pay attention to the

details!!!







You are totally correct, currently only the 220 volt is

connected.



Electricity is my weakest subject, so building confidence!









I was just thinking last night the same thing you mentioned!





The 110 Volt earth should fit inside the electric

“domino”.







My 110 volt doesn’t have any shore plug… I need to open

the box and look at what color cable I have and see where

they go.







Do you have both shore power?



If so what good options could be good to have?







I assume the 30 A 125 Volt?



http://www.frugal-mariner.com/images/img0565.png







Does any of you have other plug for European, South

American, etc. Marinas?







Once I take the pictures, i will make a post just for it.







Thanks again, sincerely, Alexandre

Alexandre,



Nicely illustrated, as always.



 Thank you for the instructive pictures!



I note that the way you have hooked



up the galvanic isolator, only the 230V shore line is



isolated.  The 110V shore line is not (yet) protected.



 You can protect the 110V shore line using the same



isolator by hooking it up similarly simultaneously.



 Disconnect the 110V ground from the common post in the



box, and connect it to the input side of the galvanic



isolator using the same connection point as the 230V

shore



ground and you have done it!  (I.e. Change your 2-wire



connector to a three-wire connector.)



That way you are protected no matter



which shore line you use!

Hello Kent,

Hum, ok.
Well, would love to hear back from Olivier or Joel on that…

Thanks again, sincerely, Alexandre

Hi
again Alex.I've
been told that the 110-220V transformer is an isolated
transformer and thus doesn't need to be protected by a
galvanic isolator.  Maybe someone can expound on that
theory.  If it's true, your 110VAC shore power may
already be protected????Kent

Good
morning Kent,



Our vessel are similar.



And if you look at all the pictures I posted, especially
Part 2, you will see I trace the wires to the automatic
switch above the genset as this is where I remember Olivier
mentioned to connect the Galvanic Isolator.



Therefore, that box “intimidates” me… and I felt
logical to connect the Galvanic Isolator to the very first
connection (which is the box on top of the forward
bulkhead).

If I did not had that box, then the first connection would
have been the automatic switch above the genset.



As Derick mentioned and was thinking the other night:
currently the 110 shore power is not protected.

Not a problem as I don’t use the 100 volt power.

By Connecting its earth to the domino, it will be.

And the Big cubical white transformer will be after and not
before the Galvanic Isolator.



Would love to hear back from Olivier on my set-up



Alexandre

Hi Alex,Your #289 is fairly

close to my #243.

I'm not on the

boat, so writing this from memory.  If I've left

something out or am still clueless about something,
please

chime in.

 If Nikimat is like

Kristy, the 110AC shore power will go directly to a box
on

the forward bulkhead, up against the cockpit floor.  It

terminates at a 110AC 30A breaker there.  From the
breaker,

it goes to your 110->220 AC transformer.  On Kristy
the

transformer is a cubical box on the forward end of the
shelf

above the generator.The converted 220AC

power output (which will be the same frequency as the
input,

60Hz) then goes back to the box on the bulkhead to a
female

plug marked "220 via the transformer" (sorry,

it's inFrench and I can't remember it exactly).
 To

use 110 shore power, you have to insert the male plug in

this receptacle. (For 220 shore power it has to be
plugged

into the other receptacle on the front of that box
marked

2"20AC Sur Le Quai".From either receptacle,

it then goes to the automatic switch which chooses
generator

power over shore power.  This is above the generator. I

don't remember how it is marked.  There is another
box

near there marked 220AC that has the relays for the Air

Conditioners that turn on the 220AC raw water pump which

cools all three A/C units.From that automatic

switch, all 220AC power goes to the 220 breakers in the

galley.

If you have a 220

inverter, power goes from it to the 220 panel
receptacles

and microwave breakers.  I think others have a little

different set up with the inverter.

In a post a year or so

ago, Olivier suggested that you could cover both 220AC
and

110AC shore power by putting the galvanic isolator in
the

ground wire that goes from the box on the forward
bulkhead

in the engine room to the automatic switch above the

generator.  My understanding is that the 110->220

transformer is an "isolation transformer", and

having it between the shore power and the galvanic
isolator

is not a problem.  The only other item that is between

shore power and the galvanic isolator with this placement
is

the 110 breaker in the box on the forward engine room

bulkhead.

Hop that

helpsKentSM243Kristy

Good afternoon Derick,







Thanks for the compliment and also to pay attention to
the

details!!!







You are totally correct, currently only the 220 volt is

connected.



Electricity is my weakest subject, so building confidence!










I was just thinking last night the same thing you
mentioned!





The 110 Volt earth should fit inside the electric

“domino”.







My 110 volt doesn’t have any shore plug… I need to
open

the box and look at what color cable I have and see
where

they go.







Do you have both shore power?



If so what good options could be good to have?







I assume the 30 A 125 Volt?



http://www.frugal-mariner.com/images/img0565.png







Does any of you have other plug for European, South

American, etc. Marinas?







Once I take the pictures, i will make a post just for
it.







Thanks again, sincerely, Alexandre

Alexandre,



Nicely illustrated, as always.



 Thank you for the instructive pictures!



I note that the way you have hooked



up the galvanic isolator, only the 230V shore line is



isolated.  The 110V shore line is not (yet) protected.



 You can protect the 110V shore line using the same



isolator by hooking it up similarly simultaneously.



 Disconnect the 110V ground from the common post in
the



box, and connect it to the input side of the galvanic



isolator using the same connection point as the 230V

shore



ground and you have done it!  (I.e. Change your 2-wire



connector to a three-wire connector.)



That way you are protected no matter



which shore line you use!

Re: [Amel Yacht Owners] illustration of the Galvanic Isolator Installation

Hello Franscisco,

What a terrible story… I would have been petrified…

Just as I was reading your previous post, I wanted to say I would have preferred changing the cable until the 230 volt box in the engine room, but definitely a difficult job, on the other hand it is correct the section is protected.

If you have the 2nd (little thicker) cable like this one
http://nikimat.com/galvanic_isolator/shore_power_tracing_3.jpg
then this is the 110 Volt cable

Meaning you also have that box
http://nikimat.com/galvanic_isolator/shore_power_tracing_19.jpg

And the big transformer:

Thanks for sharing your scary story…
Alexandre

Hello Alexandre,
According to the electrician, the
cable failed due to old age in the marine environment.
 
I had previously
noticed the cable got warm when under load.  On this
particularly hot day when the cable failed, we had arrived
back into dock about 30 minutes before, after being out at
anchor for two days or so, and so the boat was charging
batteries, plus we had three air conditioners on.  We had
all hatches closed, including the
companionway.
Our
neighbour was cleaning his boat when he saw our cable in
flames.  He shouted "fire," "fire," and
ran for an extinguisher.  We heard his cries and rushed
into the cockpit.  I saw the end of the
episode:
The cable was flat on a dock
surface, and it was spewing out fire and sparks
perpendicularly to its length  with a flame length of 3
feet (1 metre) or more.
Then just as I was thinking
of running to the dock breaker, the fire fizzled on its own
just as the neighbour arrived with a large fire extinguisher
in his hand.  By this time, all power to the boat was
already off.
I wanted the
electrician to replace all the power cable including to the
230V box in the engine room, and he looked into it, but
reported to me that it looked very difficult or impossible.
 He said that besides, the section of the cable enclosed
inside the boat, being immobile, dry and shaded, wasn't
likely to fail.  In any event, hull
No. 350 had an unused pigtail right next to the failed
cable, by the propane locker: apparently, a whole second
cable, perhaps to be used in 110V installations?  As this
unused cable was found to have continuity/end at the 230V
box anyway, the new cable connects into the formerly unused
cable, and the end of the originally used cable was left in
a pigtail in its stead.
Cheers,
PeregrinusSM2K
N. 350At anchor,
Sardinia

Re: [Amel Yacht Owners] illustration of the Galvanic Isolator Installation

Hi again Alex.I've been told that the 110-220V transformer is an isolated transformer and thus doesn't need to be protected by a galvanic isolator.  Maybe someone can expound on that theory.  If it's true, your 110VAC shore power may already be protected????Kent

  Good morning Kent,

Our vessel are similar.

And if you look at all the pictures I posted, especially Part 2, you will see I trace the wires to the automatic switch above the genset as this is where I remember Olivier mentioned to connect the Galvanic Isolator.

Therefore, that box “intimidates” me… and I felt logical to connect the Galvanic Isolator to the very first connection (which is the box on top of the forward bulkhead).
If I did not had that box, then the first connection would have been the automatic switch above the genset.

As Derick mentioned and was thinking the other night: currently the 110 shore power is not protected.
Not a problem as I don’t use the 100 volt power.
By Connecting its earth to the domino, it will be.
And the Big cubical white transformer will be after and not before the Galvanic Isolator.

Would love to hear back from Olivier on my set-up

Alexandre

Hi Alex,Your #289 is fairly
close to my #243.
I'm not on the
boat, so writing this from memory.  If I've left
something out or am still clueless about something, please
chime in.
 If Nikimat is like
Kristy, the 110AC shore power will go directly to a box on
the forward bulkhead, up against the cockpit floor.  It
terminates at a 110AC 30A breaker there.  From the breaker,
it goes to your 110->220 AC transformer.  On Kristy the
transformer is a cubical box on the forward end of the shelf
above the generator.The converted 220AC
power output (which will be the same frequency as the input,
60Hz) then goes back to the box on the bulkhead to a female
plug marked "220 via the transformer" (sorry,
it's inFrench and I can't remember it exactly).  To
use 110 shore power, you have to insert the male plug in
this receptacle. (For 220 shore power it has to be plugged
into the other receptacle on the front of that box marked
2"20AC Sur Le Quai".From either receptacle,
it then goes to the automatic switch which chooses generator
power over shore power.  This is above the generator. I
don't remember how it is marked.  There is another box
near there marked 220AC that has the relays for the Air
Conditioners that turn on the 220AC raw water pump which
cools all three A/C units.From that automatic
switch, all 220AC power goes to the 220 breakers in the
galley.
If you have a 220
inverter, power goes from it to the 220 panel receptacles
and microwave breakers.  I think others have a little
different set up with the inverter.
In a post a year or so
ago, Olivier suggested that you could cover both 220AC and
110AC shore power by putting the galvanic isolator in the
ground wire that goes from the box on the forward bulkhead
in the engine room to the automatic switch above the
generator.  My understanding is that the 110->220
transformer is an "isolation transformer", and
having it between the shore power and the galvanic isolator
is not a problem.  The only other item that is between
shore power and the galvanic isolator with this placement is
the 110 breaker in the box on the forward engine room
bulkhead.
Hop that
helpsKentSM243Kristy

Good afternoon Derick,



Thanks for the compliment and also to pay attention to the
details!!!



You are totally correct, currently only the 220 volt is
connected.

Electricity is my weakest subject, so building confidence!




I was just thinking last night the same thing you mentioned!


The 110 Volt earth should fit inside the electric
“domino”.



My 110 volt doesn’t have any shore plug… I need to open
the box and look at what color cable I have and see where
they go.



Do you have both shore power?

If so what good options could be good to have?



I assume the 30 A 125 Volt?

http://www.frugal-mariner.com/images/img0565.png



Does any of you have other plug for European, South
American, etc. Marinas?



Once I take the pictures, i will make a post just for it.



Thanks again, sincerely, Alexandre

Alexandre,

Nicely illustrated, as always.

 Thank you for the instructive pictures!

I note that the way you have hooked

up the galvanic isolator, only the 230V shore line is

isolated.  The 110V shore line is not (yet) protected.

 You can protect the 110V shore line using the same

isolator by hooking it up similarly simultaneously.

 Disconnect the 110V ground from the common post in the

box, and connect it to the input side of the galvanic

isolator using the same connection point as the 230V
shore

ground and you have done it!  (I.e. Change your 2-wire

connector to a three-wire connector.)

That way you are protected no matter

which shore line you use!

Re: [Amel Yacht Owners] illustration of the Galvanic Isolator Installation

svperegrinus@yahoo.com
 

Hello Alexandre,

According to the electrician, the cable failed due to old age in the marine environment.  

I had previously noticed the cable got warm when under load.  On this particularly hot day when the cable failed, we had arrived back into dock about 30 minutes before, after being out at anchor for two days or so, and so the boat was charging batteries, plus we had three air conditioners on.  We had all hatches closed, including the companionway.

Our neighbour was cleaning his boat when he saw our cable in flames.  He shouted "fire," "fire," and ran for an extinguisher.  We heard his cries and rushed into the cockpit.  I saw the end of the episode:

The cable was flat on a dock surface, and it was spewing out fire and sparks perpendicularly to its length  with a flame length of 3 feet (1 metre) or more.

Then just as I was thinking of running to the dock breaker, the fire fizzled on its own just as the neighbour arrived with a large fire extinguisher in his hand.  By this time, all power to the boat was already off.

I wanted the electrician to replace all the power cable including to the 230V box in the engine room, and he looked into it, but reported to me that it looked very difficult or impossible.  He said that besides, the section of the cable enclosed inside the boat, being immobile, dry and shaded, wasn't likely to fail. 
 
In any event, hull No. 350 had an unused pigtail right next to the failed cable, by the propane locker: apparently, a whole second cable, perhaps to be used in 110V installations?  As this unused cable was found to have continuity/end at the 230V box anyway, the new cable connects into the formerly unused cable, and the end of the originally used cable was left in a pigtail in its stead.

Cheers,

Peregrinus

Good morning Francisco,

Did you determine the cause of the failure?
Was too much load on the wire? Was it old?

Sincerely, Alexandre

With regard to the 32A limitation on Super Maramu,
and having had the original Amel black wire catch of fire
quite spectacularly in 2013 (fortunately at a point about 2
metres away from the hull) here's how we tried to tackle
the problem to prevent future incidents:
1.  A 30A breaker was installed
inside the lazarette at the point where shore power comes in
(just aft and above the propane locker)
2.  The replacement cable for the
burnt-up Amel black cable is the 50A standard US-yellow.
 The higher capacity should help ensure a bit more
survivability as the years go by.
3.  The replacement cable ends in a
standard yellow US 30A/125V connector, 30A overall being the
ceiling for the boat and 125V being actually acceptable for
the Mastervolt battery chargers.
4.  In order to connect to a
US-style standard 50A/220V marine outlet, we are forced to
use an adapter we built: a weatherproof box with a 30A
breaker inside.  On the shore-side, there is a pigtail with
a male plug for the 50A outlet.  On the side going to the
boat's power cable, there is pigtail with a connector
for the boat's 30A/125V plug.
In Europe, we have two
adaptors: A.  A 25-ft extension connects our
yellow 30A plug to the Euro blue 16A connectorB.
 A pigtail connects our yellow 30A plug to the Euro blue
32A connector
