Electric showers

[Phil]

Just wanted to check on the regs regarding electric shower swaps, I'm not part-P yet but I'm still permited to swap like for like. If the old shower is running off a basic ceramic fuse and no circuit breaker etc does this need uprating first like an RCD etc??

Or does the RCD only come into it on new installs?

It requires upgrading and if you are not part 'p' you should not be touching officially,replacement or not

10 mm cable is reqired and a rcd protected fuse, get a qualified spark to do it for you
