Does anyone know if its a code violation to make my own KO's over top of Concentric KO's? I know ive done it commercial, but never residential. I need 3 KO's in the bottom of a meter base and it only has 2 up to 4" Ko's. I need (2) 2 1/2 and (1) 4".

THanks

I had the same issue once. I went down to the local steel plant had a couple pieces of aluminum plate cut out exact size as the top of my panel and riveted the two together inside and out and cut new holes. looked great and inspector had no prob with it. however I was worried about the UL listing being compromised.

I make knockouts, anywhere, anysize. I've never had a problem with inspections. Just do a clean job and don't butcher the existing knockouts and you should be alright. When all else fails, use big reducing washers to cover your mistake(s)!:thumbup:
