I have my panel completely wired, the GFCI pops when I power up. I'm trying to troubleshoot so I removed all wiring from main contactor except what is in the photo. GFCI still breaks. If I remove the neutral from contactor it doesn't break. Are the 2 hot leads interchangeable? The only wired hooks up are the two hots on left side, on the right side they lead 2 the volt  meter, one neutral, and the 2 leads to the main power switch. Could my contactor be bad?
