  • Black Wire – This is the hot or load wire.
  • White Wire – This is the neutral wire.
  • Bare Copper (Green) Wire – This is your ground wire.
  • Red Wire – This wire is used for 3 or 4 way switches and will connect the switches together so they can each control your lights.

What happens if you mix up hot and neutral wires?

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.

What happens if you reverse hot and neutral wires?

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.
