How do I know if my 220 outlet is bad?
Insert the two test leads (one each) into the two “hot” slots of the outlet. For a three-prong outlet, the two “hot” slots will be slanted; for a four-prong outlet the two “hot” slots will be the two outside vertical slots. Once inserted, the voltage should read between 220 to 240 volts.
How do I know if my voltage tester is working?
To use a voltage tester, touch one probe to one wire or connection and the other probe to the opposite wire or connection. If the component is receiving electricity, the light in the housing will glow. If the light doesn’t glow, the trouble is at this point.

How to Tell if an Outlet is a 3-Phase
- Count the openings in the outlet. If there are three or fewer slots for plug prongs, the outlet is a single-phase outlet operating at 110 to 125 volts, or 220 to 250 volts.
- Set the multimeter to test AC volts.
- Test the outlet slots in pairs.
- Test the slots on the outlet in pairs.
