A Electric Panels (also known as panel board or breaker panel) is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Once electricity is carried beyond your meter, it is distributed to lights, receptacles, and appliances throughout the house by several different electrical circuits. Here we look at the load centers the distribution center or main panel and smaller subpanels used to hook up and control the various electrical circuits. Main panels come in scores of sizes and configurations. A panel might be mounted on the outside of the house, either separate from or combined with the meter. The main panel also includes some type of mechanical device for disconnecting the house’s electrical circuits from the incoming power. In most contemporary systems, this device is a circuit breaker or simply “breaker.”
