Do UK wiring regs allow a bathroom shaver-socket to be wired to the non-RCD'd lighting circuit?

Question

It would be so much easier for me to do this, which is why I'm asking (yes I know you are supposed to be part-P certified).
If not, did it used to be permitted ?

I'm thinking this might be permitted because the shaver sockets all contain isolation transformers.

Answer 1

Yes, a shaver socket can be wired to an non RCD lighting circuit. It must be an isolated BS EN 60742 (transformer) type, not just a 2 pin socket. It must be installed in Zone 2 or higher, and have additional bonding. The double wound transformer limits the voltage to earth to 55 volts.

After next year ALL bathroom circuits MUST be via an RCD. Yes - this is Part P.

Answer 2

If you're doing this in your home, there's an easier way. Plug a radio into a socket and turn it on high. Go to the load center and start turning off breakers until the radio turns off. Now you know what circuit that room is on. While the circuit is off test the radio in all the sockets until you determine which are on that circuit (dead). Try turning on the lights in that room as well because sometimes shortcuts are taken and lights are wired into the same circuit as the sockets. Label the fuse or breaker. Proceed to the next room. No tools required.

Whatever some of the other answerer's say, you cannot personally install any electrical outlet in your bathroom. It is a specific zone mentioned in Part P. You must install it correctly and have it tested and certified with an approved form of certificate. Unless you are suitably qualified (apparently you are not or you wouldn't be asking the question) this must be done by a professional electrician.

You might think that you Can get away with doing it yourself but if something goes wrong and there is a fire or fatality then your insurance will not pay out and you will face criminal charges.

AND, when you want to sell the house the lack of a part P certificate will affect your selling price and chances of a sale.

Incidentally, you should not connect any power outlet socket to the lighting circuit. Also, if the transformer developed a fault it would knock out your lights and that will certainly become a safety hazard.
