I know there's a sub-forum for overseas electrics, but since there's more people viewing here and my question is a general one, I'm posting here first:
I'm staying at a relative's house in Bangkok, and the main circuit breaker is forever tripping -- probably at least once a day, and always when someone switches off a light, not always the same light. Air conditioning compressors automatically stopping and starting don't ever seem to cause a trip. Looking at it, I see that the breaker has a sensitivity adjustment knob that is set at 5mA; from other posts in this forum it would seem that 30mA is a more-normal value in the UK, so I've suggested to my hosts that they might be better off changing the setting to 10mA (the next available setting) for a start. The settings go up to 25mA, plus a 'Direct' setting.
The voltage here is 220. Is my advice safe?
