Hi guys, iv'e got a serious question for you. I have a new consumer unit and the wiring is split into sections: lights up, lights down, sockets up, sockets down etc with a MCB protecting each section(as you do). My problem is that the MCB covering the downstairs sockets trips about once a month. I have noticed a pattern, when I switch on the washing machine, tumble dryer and kettle the MCB trips. They are all plugged into the same double socket outlet. If I am merely overloading this socket outlet then why upon testing it by plugging in everything of heavy load which I could lay my hands on did it not trip? I really put it through it's paces. I have heard about MCB's in B,C and D format. I am using B which seems rather sensitive. Should I try using a less sensitive MCB like D? regards, bob.
