What happens if you reverse hot and neutral?

One common issue with electrical outlets is reverse polarity, also known as “hot-neutral reversed.” In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.

How can you tell if a wire is polarized?
