Is a disconnect required to be installed next to a transfer switch (industrial, campus type setting) for the generator feeder. There is a generator remotely installed away from a Bldg. and the generator power enters a mechanical room. Normally, I've seen the gen. feeder go right to the transfer switch. I think it's good design, in case you want to isolate Generator power for a test, and or trouble shooting job.
Is there anything in the code that requires such a disconnect? Thanks
