1500 amp busbars within a power distribution rack for a large building

A busbar (often pronounced "buzz bar") refers in electrical power distribution to thick strips of Copper or other material that conduct electricity around a switchboard, distribution board or other electrical apparatus.

Amp re can refer to: Amp re (car) Ampere (unit) Andr -Marie Amp re This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ... Electricity distribution is the penultimate process in the delivery of electric power, the part between transmission and user purchase from an electricity retailer. ... General Name, Symbol, Number copper, Cu, 29 Chemical series transition metals Group, Period, Block 11, 4, d Appearance copper, metallic Atomic mass 63. ... Lightning strikes during a night-time thunderstorm. ... A distribution board (known in the United States as a circuit breaker panel or just breaker panel) is a mounting enclosure for multiple electrical circuit breakers. ...


The size of the busbar determines the maximum amount of current that can be safely carried. Small distribution boards or consumer units may have busbars which have a cross sectional area of as little as 10 mm2 but large electrical substations may use metal tubes of 50 mm or more in diameter as busbars. A distribution board (known in the United States as a circuit breaker panel or just breaker panel) is a mounting enclosure for multiple electrical circuit breakers. ... Wylex standard consumer unit fitted with rewirable fuses A consumer unit is a box of fuses or breakers usually arranged in a single row. ... An aerial substation A substation is the part of an electricity transmission and distribution system where voltage is transformed from low to high and vice versa using transformers. ...


Busbars are typically either flat strips or hollow tubes as these shapes allow heat to dissipate more efficiently due to their high surface area to cross-sectional area ratio. Additionally, the skin effect makes AC busbars more than about 8 mm (1/3 in) thick inefficient. A red-hot iron rod cooling after being worked by a blacksmith. ... This article explains the meaning of area as a Physical quantity. ... In geometry, a cross section is the intersection of a body in 3-dimensional space with a plane, or of a body in 2-dimensional space with a line, etc. ... A ratio is seperated by colon (:). It is a set of numbers. ... The skin effect is the tendency of an alternating electric current to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core. ... It has been suggested that this article or section be merged with :AC power. ...


Busbars may be used to carry phase (line, hot, live) voltage in which case they must be suitably insulated. Such insulation may either completely surround the busbar, or alternatively the busbar itself may be uninsulated but physically mounted using an insulating material to keep it electrically separate from its support. In the latter case the busbar is protected from accidental contact either by being surrounded in a sheet metal enclosure or by being placed out of normal reach. Neutral busbars are also insulated. Earth busbars are typically bolted directly onto any metal chassis of their enclosure. Insulators are materials which prevent the flow of heat (thermal insulators) or electric charge (electrical insulators). ... Ground or earth in a mains (AC power) electrical wiring system is a conductor that exists primarily to help protect against faults. ...


In computers the "Computer bus" allows the flow of electronic signals between components on the circuit boards. In computer architecture, a bus is a subsystem that transfers data or power between computer components inside a computer or between computers. ...
