What is the small busbar on the top of the voltage switch
A busbar is a metal bar, usually made of copper or aluminum, that carries electricity inside switchgear. It connects the incoming power to circuit breakers and outgoing circuits, helping power flow smoothly and evenly. Good busbar design helps prevent overheating and electrical. In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution, transmission, or switching substations. They are also used to connect high voltage equipment at. Busbars are conductors in switchgear that collect, distribute, and transmit electrical energy. Its primary role is to carry large current loads and connect multiple circuits together.
