how much does it cost to add a circuit breaker



Adding a circuit breaker to your electrical system is a crucial step in ensuring the safety and efficient functioning of your home or office. However, you may be wondering how much it costs to add a circuit breaker. The cost of this installation can vary depending on several factors such as the type of breaker, electrical load requirements, and the complexity of the installation process. In this article, we will delve into the various aspects that affect the cost of adding a circuit breaker and provide you with invaluable insights into this essential electrical upgrade.

The Importance of Circuit Breakers

Circuit breakers play a vital role in protecting the electrical circuits in your home or business premises. They are designed to automatically interrupt the flow of electricity when it exceeds the safe level or in the event of an electrical fault. This interruption prevents overheating, electric shocks, and potential electrical fires. Circuit breakers significantly contribute to the safety of your property and the people inside. Therefore, it is crucial to ensure that you have the appropriate circuit breakers installed and maintained properly.

The Factors that Affect the Cost of Adding a Circuit Breaker

While determining the precise cost of adding a circuit breaker depends on several factors, here are the key aspects that can influence the overall expenditure:

1. The Type of Circuit Breaker

The type of circuit breaker you choose plays a crucial role in determining the cost. There are different types available in the market, such as standard, ground fault circuit interrupters (GFCIs), and arc fault circuit interrupters (AFCIs). Each type caters to specific electrical protection requirements and comes at varying price points. For instance, GFCIs are typically more expensive than standard circuit breakers due to their additional safety features.

2. Electrical Load Requirements

The electrical load requirements of your property influence the cost of installing a circuit breaker. The electrical load refers to the maximum amount of power that can be safely drawn from the electrical panel. If your property has a higher electrical load, you may require a more robust and higher capacity breaker, which can contribute to increased costs.

3. Existing Electrical Infrastructure

The existing electrical infrastructure in your property also affects the cost of adding a circuit breaker. If your electrical panel is outdated or incompatible with modern circuit breakers, you may need to upgrade the panel before installing a new breaker. Upgrading the electrical panel can add to the overall cost, as it involves additional labor and materials.

4. Complexity of Installation

The complexity of the installation process can impact the cost. Installing a circuit breaker in a new construction project is generally less complex and more cost-effective than retrofitting it into an existing structure. Retrofitting may require additional electrical work, such as rewiring or modifying existing circuits, which can increase the overall cost.

5. Hiring a Professional Electrician

While it may be tempting to undertake the circuit breaker installation as a DIY project, it is highly recommended to hire a professional electrician. A licensed and experienced electrician ensures the installation is done correctly, adhering to all safety codes and regulations. The cost of hiring an electrician can vary depending on factors such as their expertise, location, and the complexity of the job.

The Average Cost of Adding a Circuit Breaker

On average, the cost of adding a circuit breaker can range from $200 to $500. However, it is essential to remember that this is just an estimate, and the actual cost can be higher or lower depending on the factors discussed above. To get a precise cost estimate for your specific requirements, it is best to consult with a licensed electrician who can assess your property and provide an accurate quote.


Adding a circuit breaker is a necessary investment in the safety and electrical efficiency of your property. While the cost may vary depending on several factors, it is crucial to consider the long-term benefits and peace of mind that comes with having a properly installed circuit breaker. Prioritize working with a professional electrician who can guide you through the process, ensure compliance with safety regulations, and provide a reliable installation. Remember, safety should always be the top priority when dealing with electrical systems, and a well-installed circuit breaker is a crucial component in maintaining that safety.
