I have a situation that has stumped me. I'm doing some electrical renovation at my sisters house. The house was built late 70's. Has a GE loadcenter
150 a main breaker. I'm sure the house is not grounded to todays. Anyway the problem is when I was tripping breakers to re-device each room some would trip instantly and some I was just gorilla welding, wouldn't trip at all. By the way the breakers are new. I feel this is a grouding system issue but don't understand why some trip and some dont. Thanks
