Replacing a breaker
Problem: breaker is tripping as soon as anything is plugged into any outlet on the circuit or when any one light or fan is switched on. I can't turn on any light on the circuit. I finally unplugged everything and turned off all of the fans. After that, I was able to get the breaker to reset without tripping. I figured I would try something other than the light on one of the ceiling fans after I got it reset. As soon as I plugged in a night light and pushed the button to turn it on, the breaker tripped again. Other than replacing the breaker, I don't know what it could be.
As far as I can tell, this is the breaker that is in the wall:
This is the breaker that Home Depot has in the store: http://www.homedepot.com/h_d1/N-5yc1v/R-202276733/h_d2/ProductDisplay?catalogId=10053&langId=-1&keyword=eaton+15+amp+single+pole+arc+fault&storeId=10051
I don't have a lot of experience doing anything other than replacing lights, plugs and switches but I think I can manage to replace this. Do you think it would be a problem if I used the second breaker instead?
