An electrician came in a few months ago and installed a new CU. He has passed all the electrics and supplied the paperwork for this. I’ve had lots of tripping on the 100mA RCD side but no tripping on the 30mA RCD side. The system is TT. Once ever 3 days and on the odd action once a week, there’s no pattern to it.
The electrician says there’s nothing wrong with the wiring, he’s done all his tests and it’s all been passed.
He says that it must be an accumulation that’s causing it to trip but not enough to trip the 30mA RCD.
He said the main culprits were.
1. My mains powered alarm clock. (He couldn’t under stand how or why because it doesn’t have an earth wire).
Is this possible?
2. The two extension leads I use in the bedrooms. (They worked fine over my old house and never tripped the RCD).
3. The wall boiler that I have had checked by the gas board boiler electrician. (They said its passed)
4. The dishwasher might be at fault. I had it checked by another firm that I have it insured with no fault was found and it passed. (He spent a long time running through all the programs as he checked).
His advice was to get the boiler and dishwasher checked and to bin the alarm and extension leads and get new ones. That should help.
We can’t go away for any length of time because of this problem.
What do you think the problem can be and how can I solve this myself?
Many thanks
