02125, Provider 302 is EXCELLENT. I ususally seek him out through the Massachusetts Electrical Contractors Association (MECA) He does code classes around MA usually sponsored by them. I have strayed from him in the past with less than stellar results. This guy knows his stuff and he actually is part of the board that interprets and writes the MA code changes. When I have a code question I call him. (If I can't get an answer here of course!)
