The question I have is does the neutral from the fuse box need to be (approx) twice the size of one phase, for instance if the phases are 2.5mm should the neutral be 6mm.

I think the answer is no, 2.5 the same as the phases but need to be sure.

I have rewired the whole house and balanced the three phases so I'm quite OK handling the system (passed by EDF), just this one thing I need to know.



Thanks

Are you are in a farm or an industrial building/large or multi-floorhouse to have 3 phase supply.

Any link to the wiring diagram or a scan of it. Have you actually got 2 phases on the same floor or in the same room?
