What is the maximum insulation resistance reading on a 800A busbar?
infinite
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.
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.
How can you calculate busbar size?
Busbar Length x Busbar Size x 0.009 ex- Length= 12meter Size = 60 X 10 mm ie, 12 x 60 x 10 x 0.009 Ans = 65 kg Can you please let us know what is "0.009" for??? Ans: 0.009 = copper density Max. Current for 60 x 10mm = 60 x 10 x 1.55 = 930 AMP What is "1.55" for??
What is the maximum insulation resistance reading on a 800A busbar?
infinite
How can calculate cu bus-bar breaking capacity?
Earthing busbar size
What is the maximum resolution available for Mac wallpapers?
The maximum resolution available for Mac wallpapers is only limited by the size of the Mac screen. The wallpapers themselves can be of any resolution.
What is the maximum size of memory available for dynamic memory allocation?
The maximum memory that can be dynamically allocated depends on the size of the heap memory. Dynamic blocks of memory can be allocated in system heap until it is not full.
What is the torque for a 800Amps electrical busbar?
65 N/m is sufficient for 800A Busbar.
What is meant by 1.55 in busbar current calculation?
Busbar current rating for 1 square inch is 1000a.

What is the maximum size of else-if ladder in c plus plus?
There is no preset limit on the size of an else-if ladder in C++. It depends on compiler design and available memory.

Relationship between the maximum window size and the sequence number in Go-Back -N -Protocol?
maximum window size is the difference between highest available sequence number and send_base, knowing that send_base is the sequence number of sent and not yet acknowledged packet. window size= highest available sequence number-send_base=N. note that in GBN window cannot contains already acknowledged packet.
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.
