Having just read the thread on this forum re cable size for showers, I am ‘on the horns of a dilema’ . I have just removed my 9.5kw shower in order to re-tile my bathroom - - this shower has been there ever since I have lived there, and noticed its is wired using 6mm cable. I have never had any problems with this shower but now I am a little worried about putting it back without changing this to 10mm - - I’m sure your aware of the ‘hassle’ this would be. Am I in danger of my house going up in smoke if I leave things as they are ??
