The electrician that installed the circuit panel boxes in my house didn't know what AFCI's were.
That's scary!
The new electricians looked into the panel boxes and gave them the thumbs up without the AFCI's knowing that it's a new install.
Almost as scary.
Question: It's my own house, I know they are supposed to there BUT are they proven to be helpful and should I put them in?
I think "
helpful" is the wrong word. The good folk who produce the NEC have found that they are an
"effective" and worthwhile safety device that can reduce the number of house fires caused by loose connections and other poor wiring methods. Given who did your wiring, yep, I'd want them for that reason alone. Also keep in mind that when you eventually sell the house any decent inspector is going to point out that they were required and are missing.
Is it worth the disscussion that I'd have to have with the electricians and the cost of the already purchased NON-AFCI breakers?
Yes, but I'd also suggest you have a discussion with the state licensing board regarding your electrician.
