AFCI tripping


OK, I have a AFCI tripping the kitchen dinning area and there is 2 lights and recepticles on the circuit. When I plug a sewing machine in or vacumm it trips when both lights are on. I traced the problem back to a switch. As soon as I was unscrewing the plate the plate screw shocked me. One I was in I noticed the ground to the chandlier was directly hooked to the switch and was not connected to the hot leg / other switch for the kitchen light in the switch box. When I connected all the grounds together the chandelier switch would trip the ARC fault. When I opened the chandelier cover the wires were pressed against the box so hard that the wires were exposed so I fixed the problem but the breaker still kept tripping therefore I changed it out with a new ARC fault and now its fine? Do you think I fixed the problem? I don't believe in just changing out breakers to fix a problem but these ARC faults are a pain.

You have two open treads for similar problems. I'd venture to say the problem is not the AFCI but something with the building wiring.

When you use the term ground wire are you referring to a white wire or a bare copper wire?
You would not have a ground in switch that goes to the chandelier.
