I did a search but didn't see anything on Square D AFCI's. I installed two yesterday, I tested first with Wiggy from H-N, everything ok, breakers held, then from H-G, breakers tripped as expected.
Today homeowner calls, they installed their own paddle fan, they said it trips the AFCI. They also said when they try to use a lamp on either circuit, AFCI trips. I can't go there for a few days, but I seem to remember a recall on Square D AFCI's.
Of course maybe they messed up on the fan and maybe the lamp is arcing or grd fault, I won't know till I get there. I know I didn't mix up the neutrals, besides, if I did then wouldn't the Wiggy have tripped them from H-N?
Any info would be appreciated in regards to what to look for. I have installed dozens of Cutler Hammer AFCI's with no problems.
