Electrical question - RCDs

boom

Hello

A quick and strange query for electrical eggheads.... is there any way that an RCD (in a split load consumer unit) could be tripped by something external to the house wiring?

Say if a neighbour (without an RCD) had a dodgy appliance and this was sending some current down their earth, could this in turn trip the RCDs of other houses in the street?

Thanks in advance!

There is a myriad of strange and weird possibilities relating to an individual electrical problem.

Deciding the origin really needs the investigator to see the complete installation at both properties, type of supply, type of earthing and so on. It is very very difficult to diagnose a problem of nuisance tripping of a leakage device remotely.

What seems, to the person describing the scenario, as irrelevant and therefore not mentioned may be very important to the issue at hand.

If it is a MEM one these can be iffy- had a telly trip one , the telly wasn't on the RCD side of the board.

Also loose connections on the supply side (or inside the consumer unit) could cause things to go funny.

Thanks for the info chaps - is it me or are all the electricians round here bald?


It was genuinely more of a theoretical question than a practical one so there is no more detail to give, but you are no doubt right that there is much of relevance that may not appear relevant.

Thanks again
