Any Sparks on here? Long shot....

Just wanted to know if it's still allowed (with the current regs) to feed a 3-phase board with a 3 core SWA cable, if the board is going to be used to supply small power, single phase, circuits?

I know it's good practice to use 4 core with the neutral to feed small power boards but it can be taken from the board itself by using a 3 core cable and it used to be common practice. I don't have my regs book available so can't look through it now so was just wondering if anyone on here would know.

:fcuk:

in theory yes as neutral=earth at some point but as per 17th nope you cannot do it it needs a seperate neutral core and use the armourings as earth.. if you were feeding only 3phase gear it would be fine as no neutral would be needed :)

Knew you could do it but haven't got my regs shit here to check what it says in there.

Thanks mate!

:D

Would thanks you but can't in general shat :P
