208v single phase, roof mat de icing system, trips GFPE breaker instantly. Customer initially tried using GFCI breaker wich I thought absolutely had to be the problem, switched to a properly sized GFPE breaker and it still instantly trips. Remove the nuetral jumper or install regular breaker and system operates just fine. We are waiting for specs from manufacturer because they were lost, so we have yet to ohm out each mat, but hooking up each mat individually and each one instantly trips the breaker, with no mats hooked up to the load of the stat, the breaker holds fine, no issues have been located anywhere else in the circuit from the breaker out to the equipment.
Specs just showed up, as I am typing this so we can check those, just need people back from break!
