I was advising a friend over the phone(he's doing his own little remodel) on running power for his dryer. I told him to run 3wire+ground from the panel because he had the option and I thought he was getting a new unit. Turns out he's keeping the older unit with only has 3 prong plug.
Question is what is the most proper way to address this issue? Should he rewire the old unit and put on a 4 prong plug? Or leave out a wire and stick with a 3 prong?
thanks
