Here in Jersey it's amazing to see how HO's will spend $70K and up for a top-end European import yet throw their own safety to the wayside and have unlicensed, therefore uninsured, people wire their homes. With all the laws and regulations on our books, I see poor and unsafe work almost daily. I was in a rental today and among many atrocities found five plastic countertop boxes fed with BX pushed through the NM slots and of course all had grounded duplexes that weren't grounded in a remodeled kitchen...forget about GFCI's. How 'bout some plastic boxes had the backs cut off because the wall depth was too shallow for them, yikes!
Not too long ago, I had an emergency call from a guy who let his painters wire his bathroom. When I got there he complained about what lousy painters they were...did he think their electrical work was going to be better!
There's always going to be kids making a buck on the side, we all did once, but to see all these home improvement guys doing electrical work for peanuts is a real killer.
