240v Shore Power Cable

[ctva]

I'm looking to move the shore power socket from the locker to a better location in the back of the boat but this means that I need about 2 or 3 metres of the heavy duty cable. Not being on the technicalities of this type of thing I'd be grateful if anyone knows what sort of cable I need as there is a plethora of options on the web and where best to buy. I've tried searching the forum but all results are for the shore power leads. The current one is a Titanex and about 10mm od.

I'd have thought arctic cable would be suitable... probably what your shorepower lead is.

It will probably be necessary to fit a manually reset circuit breaker in the circuit between the inlet connector and you main consumer unit unless the cable is run in trunking or conduit

Iso 13297 says

A manually reset trip-free circuit-breaker shall be installed within 0,5 m of the source of power or, if
impractical, the conductor from the source of power to the panel-board circuit-breaker shall be contained within a
protective covering, such as a junction box, control box, enclosed panel-board, or within a conduit or cable trunking
or equivalent protective covering. If the location of the main shore-power inlet circuit-breaker exceeds 3 m from the
shore-power inlet connection or the electrical attachment point of a permanently installed shore-power cord,
additional fuses or circuit-breakers shall be provided within 3 m of the inlet or attachment point to the electrical
system in the craft, measured along the conductor.​

If your installation already uses Titanex then add more Titanex.
If you can put it in a conduit all the better.

As you can only get a max of 16Amps from shoreside sockets, 2.5mm 3core cable is more than suitable, and as VicS says, get some Arctic blue cable from your local electrical wholesaler.

(blue for 240v, and yellow for 110v)

That is the size of the cable on my boat.

Many thanks for the info especially the details of the circuit breaker requirements. When I do the work, the circuit breaker will be moved with the power socket as they are both exposed in the cockpit locker so the distance wil be <30cm.

2.5mm 3 core artic is is and some conduit to protect it as it passes through the locker.

If that is correct, why do Sterling sell 16A, 30A and 50A galvanic isolators

Just wondering?

Commercial pontoons have bigger sockets on them!

Some berths, intended for large motorboats that want to run the aircon at the same time as the electric cooker, will have bigger supplies. But your standard blue commando plug won't fit them.

Ah - many thanks prv and lw395.

I am thinking too much from inside the box!

I didn't know that! I used blue in to the consumer unit, and yellow out. I thought it looked pretty, like a refresher bar.

I shouldn't be allowed near boats, should I.

I bet you have some fun with the blue, the brown and the yellow and green stripped wires then..

The same colours apply to 16A, 32A, and 63A, plugs and sockets for 110V and 240V.
415V plugs and sockets are red, and 24V are purple.

Almost a rainbow

None, it just keeps the installation consistent.

Make sure the 3 core cable is flexible - not standard domestic rigid cable used in a house.
