How to Safely Remove a Circuit Breaker

Electrical Safety Precautions

Before attempting to remove a circuit breaker, it is crucial to prioritize electrical safety. Ensure that the ground or floor and the electrical service panel are completely dry. If necessary, use paper towels or rags to absorb any moisture. Stand to the side of the panel and use one hand to switch the main breaker to the OFF position. This will cut off power to all circuits in your home.

Materials and Tools

Cordless drill or screwdriver
Non-contact voltage tester
Paper towels or rags (if needed)

Step-by-Step Instructions

1. Turn Off the Main Breaker

Locate the main breaker, typically found at the top, bottom, or side of the electrical panel. Use one hand to switch the main breaker to the OFF position. This will de-energize all branch circuit breakers and their wiring.

2. Unscrew the Panel Cover

Use a cordless drill or screwdriver to remove the screws of the panel’s outer cover. Support the cover with your free hand to prevent it from falling. Some panels have a cover that includes the door, while others have a separate door and cover.

3. Remove the Cover

Tilt the cover away from the panel using both hands and set it aside. Avoid touching anything inside the panel. The branch circuit breakers and their wiring are now de-energized, but the power company cables and their terminals remain live.

4. Test for Power

Use a non-contact voltage tester to confirm that the power is off. Touch the tester probe to the wire connected to the breaker you are removing. If the tester detects voltage, carefully replace the panel cover and call an electrician.

5. Turn Off the Branch Breaker

Switch the breaker you will remove to the OFF position. This is a redundant step but helps reinforce the habit of always turning off circuit breakers before working on them.

6. Rock the Breaker Back

Unsnap the circuit breaker from the bus bar by gently rocking it away from the center of the panel. It should come out easily by hand. Do not use tools.

7. Pull the Breaker Out

Pull the breaker straight out to release it from the bus bar. The breaker body has a tab that fits into a slot on the bus bar. You may need to wiggle the breaker or give it a gentle tug to free the tab.

8. Unscrew the Breaker Wire

Loosen the terminal screw on the back of the circuit breaker and pull the wire from the breaker. This is the hot wire from the circuit cable. You do not need to disconnect the other wires unless you are removing the cable from the box.

9. Install a New Breaker or Cap the Wire

If you are replacing the old breaker, install the new breaker now. Otherwise, you must cap and secure the hot wire inside the panel to prevent it from touching any other breaker wires or terminals.

Troubleshooting

Can I replace a breaker myself?

With intermediate electrical skills and the necessary tools, it is possible to remove a breaker yourself. However, if you are unsure about your abilities, it is best to consult a professional electrician.

Can you remove a breaker without turning off the main?

For safety reasons, it is strongly recommended to shut off the main power supply before removing a breaker.

How do I know if a breaker is bad?

Signs of a faulty breaker include a burning smell, a hot surface, and frequent tripping. A breaker that has reached the end of its lifespan (approximately 30 to 40 years) may also malfunction.
