Originally Answered: Can an electric outlet catch fire with nothing plugged into it?

Loose connections, damage, or water, can allow the electricity to “arc”.How do you test a wire with a screwdriver?Touch the tip of the tester screwdriver to the wire you’re testing, being sure to hold the tester screwdriver’s insulated handle.
