What a bus bar?
The term, 'bus', in 'busbar', comes from the word, 'omnibus', meaning 'to serve all'. A busbar, then, is a copper bar that connects several independent circuits together. For example, a generator might be connected to a busbar, serving several circuits all connected to that same busbar. There are separate busbars for line, neutral, and earthing (grounding) connections.
How do you calculate the amps rating of copper bus bars?
A formula for 60 Hz with reasonable ventilation: Imax = 7.73 x A^0.5 x p^0.39 A is the cross-section area in sq. mm and p is the circumference of the busbar's cross-section in mm. So for a busbar of 100 mm x 5 mm the maximum current is 1391 amps.

What is Bus bar electrical?
A bus bar is a solid copper or aluminium bar that is used in switch gear and motor control centers. Smaller bus bars are used in central distribution panels and seen in everyday use, the bars that the household breakers plug or bolt into in a homes distribution panel. The bars in switch gear and MCC's are rated to carry a rated current. To bend a wire into the back of these types of equipment would be next to impossible due to the constraints of limited space.Additional InformationThe word 'busbar' is derived from the word, 'omnibus', meaning to 'serve all', which is exactly what a busbar does -it serves all the circuits connected to it.Occasionally, you see the word, 'busbar', spelt as 'bussbar' -this is an incorrect spelling which indicates a lack of knowledge of the origin of the word.

What is difference between to busbar and feeder?
The busbar is used as a conductor and is used as a connection between the parallel and the feeder. The feeder is the supply, and it handles the relays.

What is mean by busbar in electrical engineering?
it is an infinite current carrying conductor which doesn't have voltage drop.
What is bus bar and how it is connected to the genarator?
The term, 'bus', is derived from the word, 'omnibus', meaning to 'serve all', and that's exactly what a busbar does.A busbar is a length of conductor which offers a common point of connection for several circuits. For three-phase systems, one busbar is required for each of the three lines and (where necessary) for any neutral. A separate busbar is used to interconnect the various earth (ground) connections.In the case of a power station, one or more generators can be connected to the same busbar system, as are the various transformers supplying the circuits leaving the power station. Normally, each input/output circuit is connected to the busbar system, not directly, but through circuit breakers and isolators.
