When fitting this boat out I have used single core cable for all the sockets. Is there going to be a problem when I need a BSC? I see they say its good practice to use multicore cable but I guess that means its not mandatory that multicore cable is used just recomended.

Do you mean 12V or 240V sockets?

[leeco]

240v sockets

Its not a BSS fail but its def not good practice.....its because of the vibration...it might fracture a single core which would cause a fire risk cos of overheating

cheers

The circuit is a ring final and it will have a rcd and mcb protecting the circuit.

Hi, assume you mean a BSS, if this is a new boat being fitted out you should be adhering to the RCD directive surely?

edited to say Recreational Craft Directive, so not to confuse Op with electrical Rcd

Its not a new boat and yed I mean BSS. Yes it will have a RCD.

im not sure what a Recreational Craft Directive is.

If its not a new boat then the directive does not concern you, though single core cables no matter how they are protected would certainly concern me.

The risk is of a core breaking within the insulation...this wont trip an RCD or MCB but given a reasonable current flow would cause an overheat hence why its not recommended. If its fitted then theres not much you can do....however if it could be changed I would be tempted just to be on the safe side.

There's a reason why the aerospace and automotive industries use multi strand cable. Exactly as described earlier - single core cables will stress fracture.

Do you mean single core i.e. single conductor (which could be solid or multi strand) and you have used 3 single cables for the AC, or do you mean multi core i.e 3 core solid conductor?

Ok I see where you are all coming from and will look into replacing it.

I mean single core conductor which is just 1 core of 2.5 mm2 copper. Twin and earth like you would use in a house.

So you think we're gonna be removing all those boards and replacing wire do you?

Yes every single one.

[Gazboatman]

Yes every single one.

Ok, let me know how you get on.

[steelaway]

Yes every single one.

Most modern boats are wired with Arctic Blue 3 core flex cable -- Cable
You do not need to run a ring circuit simply run from one to the next down the boat
The cable is rated at 16A and that's all power available from a landline / fuse / ELCB

Ooops

Why? If you were rewiring a house, you join the old cable to the new one, then pull the old one through the trunking, bringing the new one with it

It even worked for me on the lighting cable through the trunking from under the stairs up to the loft

I fitted all of my wiring in conduit. White for 12V black for 240V. Means that I can replace and update the wiring relatively easily. Would be a complete nightmare otherwise.

There is no trunking.

But suppose it still could be done this way.
