Electrical busbar systems can be differentiated by the distance between center of each busbar and vary according to maximum current carrying capacity of the system which depends on IEC standards. commonly known busbar system types. [4] 40 mm Busbar System (Current carrying capacity up to 300–400 Amps)
The 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 electrical substations may use metal tubes 50 millimetres (2.0 in) in diameter or more as busbars.
The busway is open at the bottom, and a movable collector assembly "trolley" is used to connect between the fixed bus bars in the busway and the cable connected to moving equipment. [4] Bus ducts are building service penetrants that are required to be externally firestopped where they penetrate fire separations required to have a fire ...

In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...
A Kassel kerb. The rounded section allows a tyre to ride up and realign itself. A Kassel kerb is a design of kerb (curb in US English) that features a concave-section that allows for an easier alignment for buses. The kerb was first introduced in the German city of Kassel for the low-floor tram system but has since been adopted for use at ...
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
Bus rapid transit (BRT), also referred to as a busway or transitway, is a trolleybus, electric bus and public transport bus service system designed to have much more capacity, reliability, and other quality features than a conventional bus system. [3]
