I've got an existing situation consisting of two 350kW generators which are now set up for an "either-or" type scenario. i.e. Only one runs at a time and you have to manually switch between the two.
This is a hospital incidentally and the emergency load is less than 350KW.
They would like to add synch gear such that they can utilize both generators and increase their load beyond 700kVA?
I'm wondering how the whole isolation of disconnects is going to work with this. Ordinarly per the new code rules, I'd come off the generator with a single OCP to a switchboard where LS is isolated from Critical and isolated from equipment. Or you could put the isolated breakers back in the generator. Does the code allow for the situation I have here where their will be synch gear through which all categories of emergency power will flow?
Thanks,
Mike
