For the past few weeks, we have had one of two socket circuits tripping about once a day, including at night and day, in all weathers.
The wiring is by no means new, but the consumer unit was installed only 2 years ago and the wiring fully checked. There are a few clear indications of 'DIY' jobs (three light fittings in the centre of the master bedroom?!), and we aren't fully clear as to where some of the ring circuits and spurs are.
Following advice online, we systematically switched off (and, where possible, also unplugged) each appliance on this circuit. This involved trailing cables out of windows into the garage to power freezers etc. -- our electrician assures us that we did a thorough job! Still no indication of any offending appliance to blame.
The electrician that we use -- I should add -- is 'tried and tested', not just by us but also by various relatives in the building trade who have worked with him. In his first visit, he spent in excess of 4 hours removing socket covers and testing appliances. He also examined the garage wiring and appliances, plus outdoor sockets and lights.
The strangest -- and really only -- finding was a surge on his meter when it touched a small nail in the wall. This has been there since we moved in. The electrician removed about a square inch of plaster around this, after removing the nail, but there was no pierced wire.
After he left, frustrated and apologetic, we hoped that the tripping might just stop. He'd queried that two sockets in the kitchen might be subject to condensation. However, as these had been switched off and not had plugs in them, with the tripping still happening, this seemed strange.
We asked the electrician directly if we needed a rewire, but he assured us that, even with a completely new rewire, he would be very happy with the readings he had got on the circuit, and that they are well within the 17th ed. requirements.
We've also had confirmation from a boiler fitter, happening next week, that the pump and transformer are on their way out/dodgy.
My main query is this: could faulty appliances that are switched off but still connected (e.g. boiler, cooker), still be at fault?
The electrician has since also replaced the RCD attached to this circuit AND IT IS STILL TRIPPING!
Please help!
