Fuse Box Tripping Out
10 Answers
Hello. Our mains fuse box keeps tripping out on the points switch. It will be ok for a while but trip out at intervals of anytime between 1 and maybe 12 hours. Seemingly for no reason,I have unplugged most of multi use areas ie computer,tv and outside shed but still the same trips when nothing major is on. Could the main box be at fault?
PS one thing odd is when I put the trip switch back on the washing machine lights up.and the local fuses in all connected things don’t blow.
Any help please so I could give an electrician some information

These things are an electrician's nightmare.
Because it's an MCB, then the fault is either overcurrent (overload) or short-circuit.
Intermittent faults are the worst to identify. It could be an appliance (kettle/washing machine etc).
I imagine the first thing an electrician would do (after checking all the obvious things) would be to measure the insulation resistance between Live and Neutral on that circuit.
That reading could tell him something.
A common fault is a loose connection somewhere. The resultant sparking can easily cause the MCB to operate.
Don't worry. He'll find it ;o)

Question for the experts, my oven caused the power circuit to 'blow' last week, the electrician who lives across the road kindly came over, fiddled with the consumer unit and reset it. He commented that according to a label on it it hadn't been serviced since 2009, is it usual to have them serviced? He wasn't touting for business, he was a very helpful neighbour who wouldn't take anything for his visit.
