Folks,
Ever have a project that kept you awake at night? I could use some advice with a recent insomnia issue.
I have a client with 2 sets of already placed & active cell tower equipment - one set in a shelter, another set on a slab. They are each served individually with a 120/240V, 200A, single phase service ? I assume from the same transformer. The client wants to use their existing 50KW generator that keeps the slab equipment up to also run the shelter in case of power failure. Since the 50KW gen is only going to provide about 208 amps, load shedding is the issue. Usually cell clients put in a generator rated to handle their entire cell equipment load (200A, typically), but splitting the power up like this is new to me.
Once I get past the 2 new ATSes I?m sure I need, I can?t figure out what I need to do to make sure the generator only serves the client?s critical loads and doesn?t waste power on non-critical loads like shelter lighting, receptacles, etc. I?m familiar with load shedding as a concept, but not how it actually is applied. I think I need to add a panelboard somewhere for the generator?s output, but I?m not seeing how that would help.
Has anybody done something like this that can point me in the right direction on how to handle it?
Thanks so much and may you have a happy Monday!
