Hi all, this is my first post here so a big hello to everyone first
Now down to business...
I am gutting my bathroom and as part of the renovation I'm adding electric underfloor heating, a shaver socket, and an extractor fan.
I've been sifting through posts here and through various information on the web surrounding the amendments in the 17th edition of BS 7671 and I have a few queries.
I intend to take a spur off of the ring main and through the bathroom wall for the Thermastat (which is IP20 rated and will be 'out of zones') for the underfloor heating. I then intend to wire the extractor fan (inc. timer) and shaver socket into the lighting circuit.
My question is, BS7671 now suggests that ALL bathroom electrics should be protected by a 30 mA RCD. Since my house was built pre 2008 I only have a 30 mA RCCB on my ring main so my lighting circuit is not protected, so do I need to change it so that it is as a result of these works, or can I just add to the existing setup?
Also, with regard to the extractor fan, do I HAVE to have a triple pole isolator for the fan to comply with regs or is this just a recommendation / nice to have? Does it still have to be of the pull cord variety if it's going to be in the bathroom (even if its out of the zones)?.
I will of corse be getting a professional sparky to check everything after I've finished, but it would be nice if I didn't have to change anything!
