Answer / jagadisha.n bmsit

ya we can..

Actual rating of the motor is 4000A and it was carrying
2500A load since if we connect 500A tio same busbar it
becomes 3000A so it can handled both the load but the prob
is if fault occured in 1 line both the line will trip..

arrangment the other factor which you need to consider.

1. The Rating of a transformer.
2. the Ir seeting of a Breaker.
3. Total contract demand if you are using local electricity
board power.
4. change in OT & WT setting.

by checking all the above peramiters you can go ahead.
