From Generator to ATS through Seperate Feeders
From Generator to ATS through Seperate Feeders
(OP)
We have a ATS at our remote site rated 500A.Now we want to give Generator power from Main Site to ATS at Remote site.
There are two Generators in Parallel at Main Site.Each Generator
has a spare feeder of 250A.
How we can connect these two 250A feeders to one Feeder so that
a 500A ats can be served.
I hope you understand my question.
regards
Abraham

But, as David says, probably not.
You may be able to reuse the feeders after rewiring/reconnecting them.

There is something wrong in your drawing (or something i don't get well...)
I assume that CB of 630Amps shown bellow each generator is the main CB of each generator.
Is this is true, then is not possible to have a parallel bus before generators circuit breakers!
As soon as you start the Generator will supply power to the "paralleling bus" no matter if the respectively 630Amps is open or closed and this is something you don't want.
As "waross" proposes, remove completely the parallel bus bellow generators and everything should work fine.
