I swapped out my old breaker, with gfci breaker, but when I go to turn on light it trips. My old breaker had just the hot sire going to it, but no white neutral wire. The new gfci had the hot & coiled wire which h I connected to the neutral bar, there is a screw on the gfci for a neutral wire but non on the old one. Here is the gfvi inztalled..Any ideas? Tank you.
