Enclosure comparison with normal wiring & with busbar system. Electrical busbar systems [1] (sometimes simply referred to as busbar systems) are a modular approach to electrical wiring, where instead of a standard cable wiring to every single electrical device, the electrical devices are mounted onto an adapter which is directly fitted to a current carrying busbar.
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. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks. They are generally ...
5000 ampere copper and 4000 A aluminium bus ducts. In electric power distribution, a bus duct (also called busway) typically uses sheet metal, welded metal [1] or cast resin to contain and isolate copper or aluminium busbars for the purpose of conducting a substantial current of electricity.
Seoul has 15 electric buses nicknamed "Peanut Bus" for their shape, transferring people from subway stations in downtown to the N Seoul Tower, circulating Mt. Namsan.

A smaller type of isolated-phase bus is manufactured for direct-current circuits; this may be used in the field circuit of a generator. Currently, the isolated-phase bus world record current is 52,000 A, for bus manufactured by Alstom Power (since 2015 General Electric Power) and installed at the Civaux Nuclear Power Plant, in 1997.
Trolley pole wheel on top of the trolley pole of Twin City Rapid Transit Company No. 1300. A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and EMUs to carry electric power from overhead lines, electric third rails, or ground-level power supplies to the electrical equipment of the vehicles.
Dual-mode (diesel-trolley) buses used electric traction in the South Boston Waterfront tunnel and a short surface section, and diesel propulsion elsewhere. [16] Replaced by CNG buses with extended battery mode for the tunnel. Fairhaven: 16 October 1915 1 December 1915 Experimental. Fitchburg: 10 May 1932 30 June 1946 System also served Leominster.
