Electricity keeps cutting out

[houser]

Hi,

This has been going on for about a year.

The lights will dim slightly for a second or less and then the main RCD on the consumer box will trip. This will take out power to all the plug circuits.

There is absolutely no pattern to when it happens or what I happen to be doing at the time. In fact I have unplugged all applicances etc and it still happened once. It will be OK for weeks sometimes and then blow 3 times in a day.

Two electricians have looked at it and one tested the loads on all the circuits.

Electrician is really scratching his head now, so can anyone offer any ideas?

Thanks

Mike
