How to Identify the Cause of a Tripping Circuit Breaker
Electrical Question: I have one circuit breaker that keeps tripping off.
- I tried to fix it with a new breaker.
- Where do I go from here.
- This is a problem with just one circuit.

Thanks for your electrical question Robert
Solving the Problem of a Tripping Circuit Breaker
Why Circuit Breakers Trip Off
Robert, circuit breakers rarely go bad and the majority of the time a tripping circuit breaker is due to a fault within the circuit or a problem with a device or equipment that is connected to the circuit.
Testing Electrical Circuits
- The beast way to find out if the circuit breaker is bad is to test the circuit. Typically if a circuit breaker trips off immediately after resetting it then this is a very good indication that there is a direct short within the electrical circuit.
- There are times when after resetting the breaker that it will make a humming sound and then trip off, which is typically caused by a motor or some device that is connected to the circuit that is trying to start but for some reason the device is not functioning properly.

Electrical TipThe Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical TesterThis is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use. |
