As the heart of any electrical system, it is important to understand the basis of a circuit box and the panels within. Not only is that useful in planning current or future electrical upgrades, but it will also help you optimize your electrical maintenance budget and keep your property safe. The experts at J&S Electrical Contractors Inc. explain the key components of the circuit box.
What is a Main Panel? The main panel is where the power feed from your utility company first enters your premises. It usually consists of a switch for connecting and disconnecting the power to the main panel, as well as all the subpanels that service various areas of your property. The main panel not only controls the connection for power, but also regulates the amount of power that reaches the outlet subsidiaries in the property. Technically, the main panel can have up to six circuit breakers to control the subpanels or branch circuits, but in most cases, you will find a single main circuit breaker or a pullout fused disconnector.
What is a Subpanel? The subpanels act as an intermediary between the main panel and other circuits connected to the property. They connect with the main panel through a circuit feeder with breakers at both ends. Subpanels can have their own subpanels, but they usually just control the branch circuits that go into a load or appliance. While subpanels perform many similar tasks as the main panel, they cannot independently add or generate more electrical supply since they feed off the electrical current of the main panel.
