My arc fault has tripped the circuit affects two bed rooms I unplugged everything in both bed rooms the arc fault will not reset. I pulled all receptical and switches in both rooms checking for loose wires and any bare wires. Breakers still does not reset I replace with a new arc fault breaker the problem still exists I also Putin a standard breaker and both the bedrooms are powered I,m still trying find out what and where the problem is any recommendations
Since you have removed the loads and replaced the breaker there could be a pinched or skined wire in this circuit causing the fault. A megger to verify the insulation is good is the quickest way I know. The wires are removed from the breaker and all switches off. If there is a low resistance at less than 500v there is usually a staple or nail through the insulation. If the test is good start turning on switches, lamps/ bulbs out when one circuit shows a low value this is the one to check. With all this said if you have recently added flouresent lighting, a large computer / UPS or a large dimmer on any kind of lighting circuit arc fault breakers can't tell the difference from an arc and a electronic load and will trip.
