The key to a successful electrical installation or repair is understanding your home’s electrical system – the main load center breaker panel. 

Circuit breaker boxes are the breaker panels that keep the lights on at your home or business. These breaker boxes host circuit breakers, which are small switches in electrical panels that interrupt the flow of electricity for safety reasons.

The Home Depot has all your breaker box and circuit breaker needs covered. Our wide selection of options from top brands and helpful buying guide videos are a match for your next electrical project. 

The Main Breaker Load Center Before you get started on any electrical project, please check with local authorities, your utility company and an electrical technician to make certain your installation or repair meets local code requirements.

Your electrical meter box, mounted onto your outdoor main breaker panel or inside a wall, collaborates with the load center to safely distribute the correct amount of electricity to every room and outlet in your home. 

We offer main breaker panels in a range of maximum amperages:  • 100 amp panels • 150 amp panels • 200 amp panels

Additional sizes and configurations may be available to fit your needs.

Switches, Sizes & Amps When it comes to breaker boxes, the year your house was built will typically determine the number of amps (electricity) it receives. Most circuit breakers are labeled with the amperage needed. This will help you determine how to match the total amps in the circuit breakers you plan on replacing.  

Check the electrical meter box, which can be installed inside or out, to determine the amperage your home needs. 

We offer breaker boxes in several sizes and configurations with a range of maximum amperages:  • 100 amp main breakers • 150 amp main breakers • 200 amp main breakers

Also, we offer circuit breakers for your breaker box in a range of maximum amperages: 

• 15 amp breakers • 20 amp breakers • 40 amp breakers • 50 amp breakers • 60 amp breakers • 100 amp breakers • 200 amp breakers

Additional sizes and configurations may be available to fit your needs.

Safety First  Always make certain the floor and other areas around your electrical panel are completely dry before beginning any type of electrical work. Turn off all appliances powered by the circuit breaker you are replacing. 

Be sure to add enclosures like electrical power covers, breaker box covers or sub panels to provide additional, long-term protection. Also, you can install circuit breaker lockout units to prevent accidental on and off switching during repairs.
