(OP)
I am confused about somet things regarding the installation of a 50kw gas-fired emergency generator. A 200A automatic transfer switch is also provided and connected to the generator. NEC 445.18 required a disconnecting means. It seems that these generators come with factory provided built-in load circuit breakers as well as emergency shut off switches. Is a disconnect switch still necessary? Do I have to size the load circuit breaker? I am unsure what all needs to be done on the design aspect of this as well how to size everything involved. If anyone can point me to a good source to learn these things, I'd really appreciate it. Thanks!
