I just had something like this happen on Sunday. Customer calls me up and tells me that he can't get two AFCI breakers to reset. I had installed them. He asks me how to reset them and I tell him to put the switch all the way to the off position, then back to the on position.
He said he did so but it still wasn't working. He asked if I could take a look at it, or even just replace the breakers with regular ones. I briefly considered that the breakers might just be faulty. None of the NFL games on Sunday afternoon were overly exciting so I headed down there.
I get there and he's got panel open, and he tried moving one of the wires to a spare breaker that I left in there, but didn't know what to do with the white wire and he tried putting the breaker right next to the main breaker where the bus is only wide enough to accommodate the main breaker. Anyway, long story short I put the panel back the way it was when I installed it originally (took me about 3 minutes), then reset the breakers. They energized properly.
So the guy asks me what the problem was and I show him by tripping the AFCI (test button) then putting the handle back to the off position before putting it into the on position.
He says, "OH, you have to put the switch ALL THE WAY OFF on these kind of breakers? I've never heard of having to do that before."
I gently explain that just about every breaker ever made needs to be reset that way. He seems to accept that.
I end up charging him $50 in cash, which was fine for my 30 minutes. Before I leave, he mentions that he had been an electrician's apprentice before, but obviously before these AFCI breakers came out, and AGAIN tries to sell me on the idea that having to turn the breaker all the way off before turning it on is some kind of new-fangled thing.
It was worth giving him that price just to see how ignorant he really is.
