Testing a 10 Amp Circuit Breaker

Many homeowners and do-it-yourselfers are faced with the need to test a 10 amp circuit breaker. With just a few simple steps, the task can be done quickly and safely. This article will explain the process for testing a 10 amp circuit breaker, as well as discuss safety precautions and tips for successful testing.

To begin, make sure the circuit breaker is off. If the circuit breaker is tripped, simply reset it. Once the power is off, it is safe to proceed. Now, you will need a multimeter or circuit tester for testing the circuit breaker. Multi-meters measure both electrical current and voltage, and circuit testers provide a more rudimentary check of continuity. Most hardware stores sell both and provide instructions on usage.

Next, remove the cover plate from the circuit breaker. There should be two wires connected to the breaker, one from the hot feed and one from the load side. Disconnect both wires and attach them to the multimeter or circuit tester. Set the multimeter or tester for AC voltage measurement, and then switch the circuit breaker back on. The meter should display between 110 and 130 volts.

Now, set the multimeter or tester to measure current in amps. With the breaker still switched on, place the leads of the meter inside the small slots at the front of the circuit breaker. If the breaker is working, the multimeter or tester should read between 8 and 10 amps.

When you are finished testing the circuit breaker, make sure to switch the breaker off and replace the cover plate. Do not attempt to repair the breaker if it fails the test. Instead, contact an electrician for assistance.

Testing a 10 amp circuit breaker is a straightforward process that anyone with basic electrical knowledge can do. Just make sure to take necessary safety precautions and use the appropriate tools. With a bit of knowledge and the right tools, you can ensure that your circuit breaker is functioning properly.
