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
Application: Tripping Circuit Breaker.
Skill Level: Beginner to Intermediate. This electrical project is best performed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools.
Precaution: Identify the circuit, turn it OFF and Tag it with a Note before working with the wiring.
Notice: Installing additional electrical wiring should be done according to local and national electrical codes with a permit and be inspected.
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.

The Safest Way to Test Electrical Devices and Identify Electric Wires!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 that I use to easily Detect 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.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet TesterThis is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring. It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire CutterMy absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.. The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use. |
