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!

Alexandre,
My
boat was the U.S. Demonstration boat, originally owned by
Joel Potter.  Like yours, it was fitted out with the 110V
to 230V transformer.  The plug on the end of the 110V shore
cable is like the one you have illustrated.  Originally I
used this cable in Saint Thomas, being a U.S. territory.
 Then I set up a short linker cable that could be attached
to the European 3-prong plug on the 230V cable supplied by
Amel, and convert it to a standard U.S. 220V plug.  That
230V cable is now my standard to connect to shore power,
with the adaptor linker (in the U.S. And the BVI and Antigua
and Saint Lucia) or without the adaptor linker in Guadeloupe
and Martinique.
Previous owners have gotten me well
supplied with additional short linker cables to allow
connection to other types of plugs.  
If you have not used your
transformer yet, be aware that although it will create
230Volts from 110Volts, it DOES NOT CHANGE THE FREQUENCY.
 That is to say, if the 110 Volt shore power is 60 Hz,
which would be standard, you cannot run the dishwasher,
clothes washer, or Dessalator because they require
50Hz.
Also note that
while you can add an adaptor plug that will feed you 50 or
more amps, the Amel wiring was set up to take a maximum of
32 amps.  I know you have recently installed a meter to
measure the amps and watts being consumed via shore power,
so you should have no trouble monitoring this.  Even so, be
sure not to leave your "extra" cable tightly
coiled because it will generate a lot of heat at 16 to 30
amps, enough to melt the insulation - ask me how I know
this...

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.

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?

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!

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

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,

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!

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!

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

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!
