how to replace circuit breaker with test button


Why Replace Your Circuit Breaker with a Test Button?

Are you tired of fumbling around in the dark trying to find the right circuit breaker to reset? Are you concerned about your circuit breaker's reliability? If so, it might be time to consider replacing your old circuit breaker with a more advanced one that features a convenient test button. In this article, we will guide you through the process of replacing your circuit breaker with a test button, providing you with step-by-step instructions and expert tips. With this upgrade, you will not only enhance the safety and efficiency of your electrical system but also make troubleshooting and maintenance a breeze.

Understanding Circuit Breakers and Their Importance

Circuit breakers are essential safety devices that protect your electrical system from overloads and short circuits. When an electrical fault occurs, such as an overloaded circuit or a short circuit, the circuit breaker quickly shuts off the flow of electricity, preventing potential fires or damage to your appliances and equipment. As a result, circuit breakers play a critical role in ensuring the safety and reliability of your electrical system.

The Advantages of Circuit Breakers with Test Buttons

Traditional circuit breakers typically feature either a toggle switch or a push-button design for resetting. However, these mechanisms can be cumbersome and inconvenient to work with, especially when attempting to identify the correct breaker in a panel filled with numerous switches. By replacing your outdated circuit breaker with a test button, you can enjoy several advantages that significantly simplify the process of troubleshooting and maintenance:

1. Easy Identification: Circuit breakers with a test button are usually equipped with a built-in indicator light that illuminates when the breaker trips. This feature allows you to identify the faulty circuit breaker effortlessly and saves you from the hassle of trial and error.

2. Convenient Reset: With the test button, resetting a tripped circuit breaker becomes a breeze. Instead of manually flipping a traditional breaker switch, you can simply press the test button, restoring power to the circuit.

3. Enhanced Safety: Circuit breakers with test buttons often have additional safety features, such as ground fault circuit interrupters (GFCIs) or arc fault circuit interrupters (AFCIs). These advanced technologies provide improved protection against electric shock and electrical fires by quickly detecting and interrupting potentially dangerous electrical faults.

Step-by-Step Guide to Replacing Your Circuit Breaker with a Test Button

Now that you understand the benefits of upgrading to a circuit breaker with a test button, let's dive into the step-by-step process of replacing your old breaker:

Gather the necessary tools and materials

Before you begin, make sure you have the following tools and materials readily available:

- Screwdriver (flathead or Phillips, depending on your panel)

- Voltage tester

- Circuit breaker with a test button (ensure it is compatible with your electrical panel)

- Safety goggles

- Insulated gloves (optional but recommended for added safety)

Ensure Your Safety

Working with electrical components involves inherent risks. Before proceeding, take the necessary precautions to protect yourself:

1. Shut off the power: Locate and flip the main breaker switch in your electrical panel to the "off" position. This step will cut off power to your entire electrical system, ensuring you can work safely.

2. Confirm power supply absence: Test the circuits you plan to work on with a voltage tester to ensure no electricity is present. This step ensures an extra layer of safety by confirming that the circuits are de-energized.

Remove the old circuit breaker

3. Disconnect from the power source: Once you have confirmed that the power is off, use your screwdriver to unscrew the screws securing the circuit breaker in place. Carefully disconnect the wires attached to the breaker and set it aside.

4. Double-check the wires: Before proceeding, confirm that the wires are in good condition, free of damage or wear. If any wires appear frayed or damaged, consider replacing them or seeking professional assistance.

5. Install the new circuit breaker with a test button: Carefully align the new circuit breaker with the mounting bracket in the panel. Gently push it into place until it snaps firmly.

6. Connect the wires: Reconnect the wires to the appropriate terminals on the new breaker. Ensure that the wires are securely fastened and tightened.

7. Secure the breaker in place: Once the wires are connected, use your screwdriver to tighten the screws, securing the new circuit breaker in position.

8. Test the breaker: After installation, check the new breaker to ensure it operates correctly. Press the test button, and the breaker should trip, interrupting the power flow. Use a voltage tester to confirm that power is no longer present in the circuit.

Frequently Asked Questions

Q1: Can I replace my old circuit breaker with a test button myself, or should I hire a professional?

A1: While it is possible to replace a circuit breaker yourself, it is recommended to seek professional assistance if you lack experience or are uncertain about electrical work. Working with electricity can be hazardous, and it is crucial to prioritize safety.

Q2: Are circuit breakers with test buttons compatible with all electrical panels?

A2: Circuit breaker compatibility depends on the manufacturer and the specific make and model of your electrical panel. Consult the manufacturer's guidelines or seek advice from an electrician to ensure proper compatibility.


Upgrading your old circuit breaker with a test button provides you with numerous benefits, including easy identification, convenient reset, and enhanced safety. This article has guided you through the process of replacing your circuit breaker, from gathering the necessary tools and materials to the final step of testing the new breaker. Remember to prioritize safety and consult a professional if needed.
