How Do You Fix Hot Wires and Ground Wires That Are Reversed?

Fixing a hot wire and a ground wire that are reversed is as easy as unscrewing and switching the wires on the receptacle and screwing them tight again. Diagnose the error visually by looking behind the outlet or by inserting a three-light voltage tester into the outlet and using it. Sometimes, the error is up or downstream of the outlet, which requires more work to detect.
