The electrician that installed the circuit panel boxes in my house didn't know what AFCI's were. 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.

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? Is it worth the disscussion that I'd have to have with the electricians and the cost of the already purchased NON-AFCI breakers?
