Help! I'm and idiot. I fed receptacles on A, B & C phase branch circuits sharing a common neutral. These circuits are fed by GFCI breakers. I jumped the neutral between the breakers and the breakers are tripping. I should have run a seperate neutral with each phase to terminate at the GFCI breakers. DOES ANYBODY KNOW A WIRING TRICK TO FAKE OUT THESE BREAKERS AND STILL PROVIDE GFCI PROTECTION?
