So if you reverse the polarity on a motor, it runs in reverse, right? Well, what about if that motor runs off 220v? What happens if you reverse a hot and a neutral, but the other hot wire is where it is supsed to be?
Also, what about stuff you plug in? Like a vacum, or a garbage disposal...if the hot/neutral are revesed on the receptacle, do they run backwards, too?
