Busbar, typically made from copper or aluminum, is a metallic strip or bar commonly found inside switchgear, panel boards, and busway enclosures. It serves a crucial role in local high-current power distribution. It acts as a conductor or group of conductors that collects electric power from incoming feeders and distributes it to outgoing feeders. Functioning as an electrical junction where all incoming and outgoing electrical currents converge, a busbar centralizes the electric power at a single location.

Busbar applications span various settings, including factories, data centers, retail facilities, laboratories, and technology-oriented environments.
