How To Check Circuit Breaker Amps With Multimeter

By | January 5, 2023



Are you a homeowner who needs to know how to check the circuit breaker amps with a multimeter? It's a great idea to understand exactly how your breaker is working, and using a multimeter can help you get the job done quickly and safely.

A multimeter is an essential tool for any electrician or homeowner. It can be used to measure current, voltage, and resistance in an electric circuit. It’s important to have a multimeter when working on electrical projects since it can help prevent dangerous electrical shocks.

When measuring the amps of a circuit breaker with a multimeter, you'll need to set the multimeter to AC voltage with the highest range. Then, you'll test the volts between the two wires coming out of the breaker. The voltage should indicate if the breaker is on or off. If it is on, it should read 110-120 volts. If it reads 0 volts, then the breaker is off.

Next, you'll want to set the multimeter to amperage, or current, in the breaker's rated range. Then, carefully place the multimeter's probes into the two terminals on each side of the breaker, as long as it has two screws. Make sure that the polarity is correct – one probe needs to go into the "Hot" terminal and the other into the "Neutral" terminal.

Once the probes are in place, you can take an amperage reading. This will tell you how much current is flowing through the breaker at the time of the reading.

It's important to remember to always use caution when checking circuit breakers with a multimeter. Always make sure that the circuit breaker is turned off before taking any readings, and that you follow all safety guidelines when working with electricity.

Knowing how to check the circuit breaker amps with a multimeter is an essential part of any electrical maintenance or installation project. With the right tools and safety measures, you can easily take an amperage reading and make sure everything is working properly. So don't wait, get out your multimeter and start checking your breakers today!
