Help with Equitech 1.5Q power conditioner


Hello all. My Equitech GFCI plug on the back keeps popping when I turn on the switches Equitech switches. Am I overloading the unit or is there an issue with the GFCI plug. It worked for a while but was always super easy to trip. I only have my Amp, preamp, TV, and speakers plugged into it. Any help would be appreciated. I am in in San Francisco bay area, are there recommendations to any place I can take to to get it looked at? With it tripping so much would replacing the gfci plug with a new one help (wonder if the current one is worn out?). It is out of warranty and I do not have the box it came in to ship. Thanks!

It’s already at ground potential. At the service panel the service entrance neutral conductor, electrical panel metal enclosure, and all EGCs (at panel) are bonded together.

It's close to ground potential... :)  but now you have another path which is participating in that current flow.  I'd be curious to see you measure the actual current next time. :)

Actually i think these units deliver +60 VAC on the hot and -60 VAC on the neutral. I belive that is what your meter should read when testing the outlets.  

Hot to ground +60 v and neutral to ground is -60 v.   Measuring across hot and neutral should give 120v.
