powershower on light circuit.

[arctic]

Helping a friend sort out his bathroom woes, while trying to isolate his powershower I noticed that its run from his upstairs lighting circuit on a 5 amp breaker. The shower is powered by a 3 amp fused spur outlet (1.5 mm T & E), but obviously this means that its probably not advisable to protect with an RCD (as its on the lighting circuit).

He got an "expensive" quote from an electrician to refit the same make and model and he was led to believe the guy was literally going to pull the old one and fit the new one in its place.

Am I best off running a radial from one of the upstairs sockets, and swapping the ring circuit mcb for an rcd?

Thanks,

Kev

Swap the FCU for one that incorporates an RCD

Or: do the above, but take it from the ring instead, use 2.5mm² cable, some people see this as better than taking it from the lights

Or: use current none RCD FCU, put on ring, use 2.5mm², swap MCB for RCBO (not RCD) at CU, or move MCB to RCD protected side

Cheers Adam,

I'll use an rcd protected fcu.

The main CU doesn't have any rcd protection so the rcd fcu sounds like the safest way of supplying the power to the unit.
