Sorry if this has been discussed already but has anyone used an arc fault tester that finds the arc fault. We have a house that keeps tripping but we cant find the problem even after taking all the devices out.

Replaced the arc fault breaker? Megger the circuit wiring yet? Test swap the arc with a gfi breaker and put load on the circuit?
Checked the service entrance wiring? (l just fixed an afci trip issue when I upgraded the service and had the poco redo the drop attachment splices. )



50/50 chance the problem is the breaker and not the wiring.

that will do it

I remember doing that 12+ years ago when we first started using those god awful things

Well then, I guess afci's made an electrician out of you. I too am more careful of how I make up multigang boxes, and always double check outlets to make sure the ground is not contacting neutral. Afci's have made an electrician out of me.
