Just installed a “used” Gfci circuit breaker on my panel. New CB’s not made for this older panel. Without a load wire even attached, CB will not hold and instantly trips when power is applied. Pig tail neutral attached to neutral bar. When I disconnect pigtail from neutral bus, CB will hold when power applied. So, what gives? Bad breaker or something else? Thank you for any response.
