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 ...
A plug-in bus duct system or busway can have disconnect switches and other devices mounted on it, for example, to distribute power along a long building. Many forms of busway allow plug-in devices such as switches and motor starters to be easily moved; this provides flexibility for changes on an assembly line, for example. [ 4 ]
Isolated-phase bus is made in ratings from 3000 amperes to 45,000 amperes, and rated for voltages from 5000 volts up to about 35,000 volts. In the larger current ratings, dry air is forced through the enclosures and within the tubular conductors for forced-air cooling of the conductors. The cooling air is recirculated through a heat exchanger.
The width of devices that are mounted on a 35 mm "top hat" DIN rail generally use "modules" as a width unit, one module being 18 mm wide. For example, a small device (e.g. a circuit breaker) may have a width of 1 module (18 mm wide), while a larger device may have a width of 4 modules (4 × 18 mm = 72 mm).
The highest price that O.G. Barbs has gone for is a whopping $27,450, although the most expensive one on eBay right now is a slightly more modest $16,000 — still a far cry from $3. 2. Pink ...

A bus coupler is a device which is used to couple one bus to the other without any interruption in power supply and without creating hazardous arcs. A bus coupler is a breaker used to couple two busbars to perform maintenance on other circuit breakers associated with that busbar.
