A panel board, also known as a distribution board or breaker panel, is a crucial component in electrical systems, responsible for controlling and distributing electricity throughout a building or facility. It consists of a metal enclosure housing circuit breakers, fuses, switches, and other electrical devices that regulate the flow of electricity to various circuits. Panel boards are typically installed in a central location, such as an electrical room or utility closet, and serve as the primary point of connection for incoming electrical power. They organize and protect electrical wiring, provide overload and short-circuit protection, and facilitate the safe and efficient operation of electrical equipment and appliances.
Panel boards come in different sizes and configurations to accommodate the specific needs of different installations, from small residential setups to large industrial complexes. They play a critical role in ensuring the safety, reliability, and functionality of electrical systems by providing centralized control and distribution of power.
