Hi,
One of the RCDs in my consumer unit (Volex VCU6) is tripping and won't stay "on". This is for a downstairs lighting circuit comprising dining room light, hallway, outside light and 2 lounge lights. The MCB for this is rated as 6A. The house is less than a year old and I've not added to any of the circuits in any way. So, first question, is this an appropriate rated MCB for this circuit?
Last weekend I had a power outage which was traced to an isolating switch inside my meter box. One of the cables into this switch had not been properly clamped, and so over time had arced and melted. The engineer from the electricity board did not replace the isolating switch, but just wired things back up, as he did not favour the use of such switches for precisely this sort of problem.
Since then, I cannot get the RCD for the lighting circuit to stay on. Is it possible that the problem with the isolating switch has caused this particular MCB to become damaged? Can I test this? Even with the power off at the main switch of the consumer unit, the MCB will not stay in the ON position. Is this normal?
Or, as I've read on other posts, am have I got some kind of residual Earth leak somewhere in the circuit?
Thanks in advance for any advice offered.
