"earth leakage current" catalyst 3750

Unanswered Question
Jan 11th, 2009

we are in the process of replacing Cat 3524 stacks with Cat 3750 stacks, these are all Poe switches, we have found on a number of occasions as we build the stacks the mains power breaker will trip

as the breakers are rated at 20 amps and we are only drawing 7 amps that the problem is to do with earth leakage current. It usually occurs as we add the 3rd or 4th switch to a stack,

anybody seen this problem before?

I have this problem too.
