Cheers Notts. I expected it to be low...crappy old things. Looked at job tonight. Wylex on PME - 16mm tails, 6mm earth and bonds. 10.8kw shower on 6mm and 30 Fuse. They wondered why it blew after 10 mins. Instruction say shower to go on RCD.(He wants it sorting) No supp bonding bathroom and plumbers put in shower. (Sounds like a diy botch to me). He only called me out to have a look at some lights that did not work. Sound familiar ? Want a little job doing and you end up doing loads. Well that is if i get the job, after half hour of explaining why all these things needed upgrading after 40 years!! The stares and silence you get at times and the feeling from them that you are making all this up to make cash ! OH - a house with mcbs, rcd 10 + 16mm anytime !
