I have just installed GE type AFCI breakers.
When I turned it on it tripped right away.I checked for neutral to groung contact and for shorts. I turned off the light switches reset the breaker it stayed on. As soon as i turned on one of the light switches the AFCI tripped. I started taking apart light fixtures nothing obvious. I called a friend of mine and he said test install a regular breaker and see if it trips voila all lites were on and no tripping. I did notice a loose connection under one of the wire nuts for the hots. I tightened and reinstalled the GFCI breaker and everything worked fine since. I guess my question is was this supposed to happen
?
