How To Use A Digital Multimeter Test Circuit Breaker

By | December 29, 2022



Testing a circuit breaker is an essential part of any electrical work, yet it can be intimidating for those who don't have a lot of experience with circuitry. To ensure that your circuits are functioning properly, it's important to use a digital multimeter to test the breaker. This guide will walk you through the steps to make sure that everything is in good working order.

First, turn off the electricity to the circuit being tested. This will ensure your safety and ensure that the test results are accurate.

Next, attach the red lead from the digital multimeter to the breaker’s positive terminal and the black lead to the negative terminal. Turn the power back on, and the multimeter should display a reading. Depending on the type of breaker and meter, the range of readings will vary.

If the reading falls into the acceptable range, the breaker is functioning correctly. You may need to adjust the breaker’s sensitivity if the reading is too high or low. Adjusting the sensitivity involves turning a dial on the breaker itself, which can be easily done with the help of an instruction manual.

On the other hand, if the reading is outside the acceptable range, then the breaker has likely failed. In this case, you'll need to replace the breaker with a new one. It's important to use one that is of the same voltage and current rating as the old one.

Once the new breaker is in place, repeat the previous steps to test it again. Ensure that all connections are secured and that the breaker is properly mounted. This will ensure that the electrical connections are safe and reduce the possibility of a short circuit or other hazards.

In addition to testing circuit breakers, you can also use a digital multimeter to test other components of an electrical system, such as outlets and switches. Knowing how to use a digital multimeter is an essential skill for anyone looking to work with electricity. With the right knowledge and the right tools, you can ensure that your system is functioning properly and safely.
