Nebraska also has not yet adopted the AFCI thank goodness.
A number of my service calls on newer houses have been caused by thier tripping. Out of over 40 calls I have found only one circuit problem. (HO added an outlet and did not hook up ground wire.) A new AFCI usually trips in a couple of days but placing a GFCI breaker in the AFCI's place has yet to trip.
I aam still of the opinion that, while the AFCI concept is a good idea, the products offered are expensive junk. Have had problems with all makes.
By the way the contractors who built these places do not seem to respond to service call requests very well. They almost always seem to wait until thier warrenty period is over then give the HO a bill for a service call and put in a new AFCI. At least 5 HO's have shown me thier billing for thier service calls with the notation that the new AFCI is NOT warrented.
Makes you wonder why they won't stand behind thier work.
