A busbar is a metallic strip or bar used to conduct electrical current within an electrical distribution system or switchboard. It serves as a common connection point for multiple electrical circuits, allowing the transfer of power between various components such as circuit breakers, switches, and electrical loads. Busbars are typically made of copper or aluminum due to their high conductivity and durability. They are essential components in industrial and commercial electrical installations, providing a reliable and efficient means of distributing electricity throughout a facility.
