Oh where to start...
Are the loads connected on the other end?
Are the breakers terminated?
Feeder cables meggered?
Voltage checks?
Coordination study done?

can you elaborate on coordination study? Would the settings on the 1200 and 800 breakers be determined by EE? The drawings are vague as to any settings or any test that needs to be done for equipment.

Do you know what a coordination study is?
Have you worked on switchgear of this size before?
Be honest, are you in over your head?

A coordination study is something that is your responsibility if you are furnishing and installing the board. It can cost big$. Are there specs on this job? If so...read them

Yes to all the comments above and no there arent any specs other than oneline and load analysis. I will request an RFI for this information from EE but I was looking for a little guidance with this project so if your willing I can provide all the information needed to get me down the road. I appreciate any help

That is all covered during the commissioning process? Assuming he means commissioned by a 3rd party per ANSI/NETA ATS standards

And by the vagueness of the OP's original post, I would assume nothing.. The "commissioning" may have been a megger on the bus for all we know.. Megger feeders to the main breaker? Who knows..
