One day, I was happily working away at my computer when suddenly, the power went out. I checked the breaker box and saw that the circuit breaker had tripped. I reset the breaker, but the power still wouldn’t come back on. I was confused and frustrated, so I decided to call an electrician.

The electrician came over and quickly diagnosed the problem: the polarity of the outlet was reversed. This meant that the hot and neutral wires were switched, which can be dangerous and cause damage to appliances. The electrician fixed the polarity and the power came back on. I was relieved, but I also wanted to learn more about what had happened.
Understanding Reverse Polarity
Polarity is the direction of current flow in an electrical circuit. In a properly wired outlet, the hot wire is connected to the brass-colored terminal and the neutral wire is connected to the silver-colored terminal. When a plug is inserted into the outlet, the current flows from the hot wire, through the appliance, and back to the neutral wire.
However, if the polarity is reversed, the current flows in the opposite direction. This can cause appliances to malfunction or even be damaged. In some cases, it can also be a fire hazard.
How to Check for Reverse Polarity
There are a few ways to check for reverse polarity in an outlet.
Using a Voltmeter
- Turn off the power to the outlet at the breaker box.
- Remove the faceplate from the outlet.
- Set your voltmeter to the AC voltage range.
- Touch the black probe of the voltmeter to the brass-colored terminal and the red probe to the silver-colored terminal.
- If the voltmeter reads 120 volts, the polarity is correct.
- If the voltmeter reads 0 volts, the polarity is reversed.

Using a Non-Contact Voltage Tester
- Turn off the power to the outlet at the breaker box.
- Remove the faceplate from the outlet.
- Touch the tip of the non-contact voltage tester to the brass-colored terminal.
- If the tester lights up, the polarity is correct.
- Touch the tip of the non-contact voltage tester to the silver-colored terminal.
- If the tester lights up, the polarity is reversed.
How to Fix Reverse Polarity
If you find that the polarity in an outlet is reversed, you will need to fix it. This is a relatively simple process, but it is important to follow the steps carefully.
- Turn off the power to the outlet at the breaker box.
- Remove the faceplate from the outlet.
- Loosen the screws that hold the wires in place.
- Switch the hot and neutral wires.
- Tighten the screws.
- Replace the faceplate.
- Turn on the power to the outlet at the breaker box.
Tips for Fixing Reverse Polarity
- Make sure that you turn off the power to the outlet before you start working on it.
- Be careful when working with electricity.
- If you are not comfortable working with electricity, call an electrician.
- Do not use an outlet that has reversed polarity.
