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.
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.
For connection plates = 10-15 Nm

This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.
65 N/m is sufficient for 800A Busbar.
Busbar current rating for 1 square inch is 1000a.

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.

it is an infinite current carrying conductor which doesn't have voltage drop.
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.
