A service panel is an essential component of a building's electrical system. It houses circuit breakers or fuses that control the flow of electricity to different areas of the structure. This panel ensures that electrical circuits are protected from overloads and short circuits, helping to maintain safety and functionality. Typically located in a basement, garage, or utility room, the service panel connects to the main power supply from the utility company. It distributes electricity to various circuits throughout the building, powering devices and appliances. Regular maintenance of the service panel is important for preventing electrical hazards and ensuring efficient operation.
