I am working on a lab at a hospital that was brought in as a modular building. It is a 6 section modular. It has it's own generator for emergency power and it's own service. (1PH, 120/240) When it was brought in there was only going to be a covered walkway between the main building (Main service with its own generator for emergency power, 3PH, 120/208).
Now, they made a permanent structure between the two buildings, connecting them with the middle area being used as a waiting area. The waiting room feeds off of the main building power.
The lab is bringing in more equipment than initially anticipated and if they bring in any more, I'm concerned that the load may exceed the generator's capabilities.
Can an emergency power source be brought in from the main hospital's emergency system and used in the lab as long as there is a clearly labeled disconnecting means at the entrance point of the lab, and clearly labeled face plates where this equipment is located, along with any junction boxes?
So, why did they bring in a different kind of service and a generator so small? Because this was going to be a less permanent situation than it ended up being. They didn't need or want 3 phase. They already had the generator at another location, so they were trying to utilize what they had.
I have been checking the NEC all day and can't find a definite answer, or at least one that I'm clear on.
