How to Reset Main Circuit Breaker


The main circuit breaker is a crucial component of any electrical system. It is responsible for protecting the electrical system from overloads and short circuits, ensuring the safety of your home or office. However, there may be instances when you need to reset the main circuit breaker due to a power surge or other electrical issues. Knowing how to properly reset the main circuit breaker can save you from potential hazards and inconveniences. In this article, we will guide you through the process of resetting the main circuit breaker safely and efficiently.

The Importance of Resetting the Main Circuit Breaker

The main circuit breaker is designed to detect and interrupt excessive electrical currents. When a fault occurs in the electrical system, such as an overload or short circuit, the main circuit breaker trips, disconnecting the power supply. Resetting the main circuit breaker is essential to restore power and ensure the smooth operation of the electrical system.

Identifying the Main Circuit Breaker

Before we delve into the process of resetting the main circuit breaker, it is crucial to identify its location. The main circuit breaker is typically housed in the electrical panel, also known as the breaker box. It is usually a large switch that controls the flow of electricity through the entire building. To locate the main circuit breaker, follow these steps:

1. Locate the Electrical Panel: The electrical panel is usually installed in a dedicated area, such as a utility room, basement, or garage. Look for a metal or plastic box with a door that can be opened.

2. Open the Electrical Panel Door: Gently open the door of the electrical panel by removing any screws or latches. Take caution as the electrical panel may contain live wires.

3. Identify the Main Circuit Breaker: The main circuit breaker is usually larger in size compared to the other breakers in the panel. It is often labeled as "Main," "Main Breaker," or "Main Disconnect Switch." The main circuit breaker is typically positioned at the top or bottom of the panel, and its handle is usually colored differently to distinguish it from other breakers.

Resetting the Main Circuit Breaker

Once you have identified the main circuit breaker, you can proceed to reset it. Follow these steps carefully to ensure a safe and effective reset:

1. Turn Off Appliances: Before resetting the main circuit breaker, ensure that all appliances and electrical devices in your home or office are turned off. This precautionary measure prevents sudden power surges when the circuit breaker is reset.

2. Identify the Tripped Breaker: Upon opening the electrical panel door, look for any breakers in the tripped or "Off" position. A tripped breaker is usually in a middle position between "On" and "Off" and may have a red or orange indicator.

3. Reset the Breaker: To reset the main circuit breaker, firmly push the tripped breaker to the fully "Off" position first. Then, gently push it back to the "On" position. You may hear a click when the breaker resets.

4. Test the Power: After resetting the main circuit breaker, test the power in your home or office by turning on a few lights or devices. If the power is restored, the reset was successful. If not, consider contacting a qualified electrician to inspect the electrical system for any underlying issues.

Preventing Future Circuit Breaker Trips

While resetting the main circuit breaker may solve immediate power supply issues, it is crucial to identify and address any underlying problems to prevent future tripping. Here are some preventive measures you can take:

1. Limit Electrical Load: Overloading the electrical system is a common cause of circuit breaker trips. Be mindful of the number of appliances and devices connected to a single circuit. Distribute electrical loads evenly across multiple circuits if possible.

2. Check for Faulty Appliances: Faulty appliances can cause short circuits and trip the main circuit breaker. Regularly inspect your appliances for frayed wires, loose connections, or signs of damage. Replace or repair faulty appliances promptly.

3. Avoid Extension Cord Overuse: Overuse of extension cords can overload circuits and increase the risk of circuit breaker trips. Whenever possible, connect appliances directly to wall outlets and minimize the use of extension cords.

4. Seek Professional Help: If you experience frequent circuit breaker trips or suspect an underlying electrical issue, it is essential to consult a professional electrician. They can assess the electrical system and make any necessary repairs or upgrades.


Resetting the main circuit breaker is a straightforward process that can be performed safely by following the steps outlined in this article. Always exercise caution when working with electricity and, if in doubt, seek professional assistance. Remember to take preventive measures to minimize circuit breaker trips and ensure the smooth functioning of your electrical system. By understanding how to reset the main circuit breaker and following the necessary precautions, you can maintain a safe and reliable electrical system in your home or office.
