hello just a quick question, i bought a shower in the week it was 10.5 kw, the old shower we had was already in the house when we bought and i am presuming it was no more than a 8.5 kw, i paid a plumber 80 quid to put it in, it worked fine when he left but hubby had a shower and it switched itself off. We have replaced the shower switch, and found that the 45 amp fuse (enclosed one) mustve blown cos when we changed it the shower is now working. My stepdad has been for a visit and is convinced we have to get an electrician out to look at it because the plumber didnt change the cable we think the current cable is a 6mm is this ok to use, or do we need to get an electrician out to replace it. Very scared to use the shower at the moment as we have 2 small children, what do u guys think, and if the cable needs replacing how much do u think an electrician will charge us, thanks for any replies
