Question: Will an outlet work if wired backwards?

Most electrical outlets (properly called receptacles) today are grounded three-prong outlets. But heres the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward.

What happens if white and black wires are reversed?

When the wires are connected properly at the electrical panel and terminated correctly at the receptacle, all is fine. If the white and black wires get swapped somewhere along the way, trouble may be right around the corner.

Will outlet work if hot and neutral are reversed?

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 do I know if my outlet has reverse polarity?

Measure the voltage between the wider opening and the ground. It should be zero. If your readings are reversed, your polarity is reversed.

How do you check if an outlet is wired correctly?

Set a multimeter to measure voltage. Insert a probe into each slot and read the line voltage measurement. A properly working outlet gives a reading of 110 to 120 volts. If there is no reading, check the wiring and the outlet.
