Shore power fittings on yacht

[Peter]

Fitting a 240v shore power lead to my yacht. My question is what should the boat fitting be, using the “blue“ power connectors, excuse me if my jargon is incorrect. Should I fit a socket, same as the marina power point fittings or the plug type fitting. Or are they any elec standards one needs to follow. Hope this gives enough information.

The hot wire must always use a female fitting so there is no chance of you touching the live pins. So the socket on the boat will have male pins.

don't want to teach grandma to suck eggs, but don't forget to fit RCD's as well, and then you'll need to bond ac to dc earth, which also means a Galvanic isolator.....

a 240v install on a boat without RCDs is IMHO very dangerous.... and I believe (?) illegal.....

RCDs yes ... bond the earth from AC to DC earth (I assume you mean negative terminal) ... not always ...
Our shore power has the Male socket in the stern locker - connected directly to an RCD (twin circuit) - bit like the ones in a domestic supply - and from that it feeds the immersion heater (500w) and a double 13A socket by the Nav seat.
As we don't have a permamently fixed battery charger or any other 240v equipment, any extra bonding is (IMO) not really nessersary.

In the middle of fitting shore power myself.
Anyone know where we can look at some diagrams for setting up 240v.

AFrogley,

Sorry, I assumed that a 240V installation would include a charging set up, in which case you would need an AC/DC bond for the RCD to work reliably... I agree that without the charging system the RCD would work correctly without a bonded negative/earth...

AFrogley,

As an aside, what Immersion heater set up do you have, as this kit is on my list as well!?

I have a direct cooled engine, so a 240V immersion appeals for day sailing purposes.....
