I have an out building where I cannot add a Gfci of any sort (Breakers or receptacles). I have added breakers and they appear ok until you add a load to them; at which point they trip.
I have 2 feeds that come from the main meter base - 1 goes to a transfer switch for the main residence ( there is a generator at this house), the 2nd goes to the out building. The pull to the outbuilding is continuous and lands in a 125a load center. It is 240v single phase and terminates to a double pole main breaker. There are 4 breakers in addition to the main in the load center: 1 for lighting, 1 for a single exterior receptacle, 1 for a single interior receptacle that will be used for landscape lighting transformer and 1 for all the interior receptacles. The single exterior receptacle and the circuit for the interior receptacles have GFCI breakers. The light circuit and single interior receptacle breakers are standard. The lights operate with no issues as does the single interior receptacle. The GFCI breakers appear to be ok until I apply a load to them(I was using a box fan), at which point they trip. I took a clamp on, and with the lights on measured current on the hot leg and the neutral and I was seeing a difference of .1 to .2 A so there is some leakage current.
Another data point, the main residence has numerous GFCI receptacles and breakers which operate with no issues.
My question is this: could the issue be a result of the generator transfer switch and if so, since there is nothing to repair, what can I do to resolve the issue?
