Hi Im Wiring electric shower using a 10mm cable from shower unit to consumer unit, I have managed to find a pretty good route without lifting any floor boards but the problem I have is that the electric cable would be about 2 inches away from a hot water pipe that goes into the boiler would this be okay and how far should i be to be safe? one more question would it be okay to run the cable through the boiler room? Also is it madatory to have the electric cable running from behind the wall & tiles or can I use a condiut or chase it, please help
