Load centers are electrical service panels that act as a switchboard for all electricity in a building or house. It receives the incoming power from the utility and distributes it to each of the circuits that supply power throughout the building. This power may operate machinery, lighting, computer systems, and other devices or equipment. The utility power can be shut off and turned on at the service panel. A load center is a steel box with a hinged door or lift-up panel on the front. With the door open you can access all the circuit breakers in the panel. Graybar has a strong partnership with load center manufacturers which allows for confidence in choosing quality, dependable, and safe equipment. Choose from load centers, load center covers, and load center accessories to narrow your search.
