Why do some electrical faults seem to appear only when it rains?
This happened at a house I was staying at where something would occasionally trip during really wet weather, but then everything could be completely normal for days.
The first assumption was obviously “something is faulty”, but the fact that it seemed connected to heavy rain made the whole thing much stranger.
I know this isn't something a homeowner should try diagnosing themselves, but I'd love to understand the electrician's perspective.
