(Summary description)When the dense busway current reaches 4000A. Due to the magnetic effect, the cable not only has a reduced current carrying capacity in the tray, but also the unequal sharing of degradation can make the current imbalance between the parallel conductors close to 20%. There may also be problems with shorting the cable in the tray support. Cable busway vendors use simulation procedures to determine the optimal configuration of the cable bus phase conductors. The cable bus uses support blocks to store cable cooling and short-circuit support.

Information
When the dense busway current reaches 4000A. Due to the magnetic effect, the cable not only has a reduced current carrying capacity in the tray, but also the unequal sharing of degradation can make the current imbalance between the parallel conductors close to 20%. There may also be problems with shorting the cable in the tray support.
 
Cable busway vendors use simulation procedures to determine the optimal configuration of the cable bus phase conductors. The cable bus uses support blocks to store cable cooling and short-circuit support.
 
1. Installing a connection this way is a problem. The electrician did not like the 1000 MCM conductor when installing.
 
2. If you are not sure about the busbar size and labor is not expensive cable bus is good. It takes time to assemble and terminate all of these cables.
 
The terminal switching time may use more space than the bolting of the busway.
 
The 3.4000A current is related to the equivalent problem of using the bus plug to connect the load at the intermediate point of the busway. This problem requires professionals to solve and propose solutions.
