Bus stop power distribution box
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 electrical switchyards, and low-voltage equipment in battery banks. They are generally uninsulated, and h. Design and placementThe busbar's material composition and cross-sectional size determine the maximum current it can safely carry. Busbars can have a cross-sectional area of as little as 10 square millimetres (0.016 sq in), but. • – Data transfer channel connecting parts of a computer• – Low resistance electrical conductor for high current transmission and distribution• – Modular approach t. • Elmore, Walter A.
