Yeah, on the other hand, I've hired electricians that do pretty crappy work, too. I'm talking stranded wire wrapped around a screw with half the strands coming out, feeding a high-current device.
That is actually one of the things that drives me nuts about electricians: Many use of the cheapest grade carp, and tend to recycle stuff like switches and receptacles that should be retired/recycled. In my case (above) the use of a side-clamping receptacle (all of $1.50 or $2) would have been the right move. But the electrician used a $.33 receptacle (the price tag was still on it!) because it was cheap.
Or another case where an electrician (a different one) ran some cables behind an HVAC return he just "shoved them up there." Inspector didn't catch it, would have flagged him had he caught it. Perfect application for bridle rings.
