I realise that any circuit or appliance if left plugged in can trip the system even if they are switched off by touching neutral to earth
Really gets my goat that one! The amount of times I have seen thatI have found that the downstairs sockets require me to switch off 2 mcb to isolate 1 circuit
Correct, certainly not an intermittent one. The usual suspects (enjoyed that movie) of night 'nuisance tripping' are 'fridges and freezers.I don't think that would cause a trip problem
SparkRite beat me to it, Fridges and freezers , or anything that comes on intermittently. In my case it was the septic tank pump. Took a while to track down.
Yes I agree to a certain point, as ELCBs are 'old hat' these days, but in this case, it may be akin to 'using a sledgehammer to crack a nut'.but while the electrician is there have them replace the ELCB with RCDs on individual circuits.
Phone chargers usually employ 'double insulation et al' and are not earthed.Thanks all, one thing to note is there are so many small power packs plugged in around the house for mobile phones, cordless phones, electric clocks, modems, even TVs and satellite boxes.
You can stay sitting down, that is correct.I stand corrected but if 2 or more appliances have a small leak they could total up to make the full 30mA trip limit
Nope, as our peculation area is slightly higher than the septic tank (don't ask), the pump was triggered to pump up to the peculation area when the 2nd chamber of the septic tank reached the float switch level. Standard greywater pump with float switch.Yep, pumps as well, but I'd give odds that it was tripping more often that once every few months.?

Nope,
Happened every few days/nights
one last point I assumed it was an ELCB it could be a RCB on looking at it, it has the letters BPC?
Post a close up pic and I'll have a look.
