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

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 helps

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!
