[QUOTE="ProDave, post: 393432, member: 6969"] He will have performed an insulation resistance check at possibly 500V or even 1000V He should have unplugged everything first as no doubt he will have got a poor reading with stuff plugged in so he should have investigated that. In spite of the high voltage, the current available is tiny so it is very rare for stuff to actually get damaged but it sounds likely that's what happened here. [/QUOTE]
