I saw a short piece on the news about a homeowner that was electrocuted just days after moving into his new house. It happened near me in Clermont, Florida. They didn't give much information on the news, but they did show part of a video taken by the HO's wife's lawyer. Apparently the guy was killed when he was connecting the clothes dryer vent hose onto the metal duct. The duct had voltage on it. The video showed an electrician reading 120vac on the metal part of the bathroom medicine cabinet. He checked the cabinet and used the ground on the nearby receptacle. The investigation found a drywall screw through a metal wall stud and into an unsupported piece of nm inside the wall. They said it was only into the ungrounded conductor in the romex. Supposedly the metal studs were energized, and I'm guessing that the dryer duct was secured to the studs. You would think the breaker would have tripped, unless they had poorly installed grounding, also.

Edited for spelling
