Dear IET forum,

I'd like to get a shaver socket installed in a cupboard that used to hold an immersion heater, adjacent to the bathroom. The cupboard currently has a standard single socket, supplied direct from the consumer unit by a dedicated supply with an MCB rated at 16 amps that I presume used to power the heater. This circuit doesn't supply power to anything else, nor do I plan for it to do so.

Ideally, I'd like to use the existing wiring, rather than running the shaver socket off either a ring main or lighting circuit. Questions:-

1) is this possible?

2) would it only require someone to replace the MCB with one at a lower rating of, say, 3A and install the shaver socket?

3) would it be necessary to install a 3A FCU to protect the shaver socket? If so, would a change to the MCB also be necessary?

Many thanks

Leo
