In Paralleling busbar with different cross sectional area then what would be the effect on the smaller one?

if the bus-bars are used as the neutral or ground, then 0v would return. nothing will happen except for less room for connections

What is current density of copper busbar for 4000A?
The current density for a copper busbar will vary as the size of the bar. And no, that's not a trick answer. More information about the application is needed to determine what size the busbar is, since only the ampacity was cited here. There are different specifications (sizes) for busbars, as you know. The deal is that there is usually a "temperature rise" factor that delimits what you're supposed to use. Higher temps mandate bigger bars, which you probably already figured out. The basic busbar size is set on how much heat the busbar will generate when conducting it maximun rated current. But factors regarding the thermal environment in which the unit is operating must be considered. Minimum size for 4000A is probably 1/4 x 10, but some applications will require up to 3/4 x 10 with some allowing something in between. With a specified size bar, you can easily calculate the current density by dividing the current (4000A) by the cross-sectional area. Pick one and go for it.
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.
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 the maximum insulation resistance reading on a 800A busbar?
infinite
What is the torque for a 2500Amps electrical busbar?
For connection plates = 10-15 Nm
Why you use bus bar in transfermer?
The term, 'busbar', is derived from the word, 'omnibus', meaning 'to serve all' (the commonly-seen spelling, 'bussbar', is incorrect). A busbar, then, is a length of conductor, of suitable cross-sectional area, to which a number of common circuits can be connected. In a substation, transformers often energise busbars to which many circuits can then be connected.
What is the torque for a 800Amps electrical busbar?
65 N/m is sufficient for 800A Busbar.

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.
