Would like to know if a service with seperate disconnecting means one 800amps and the other 1600 amps derived from the same transformer system and both feeding one building, can feeder conductors meet in a shared J-Box ahead of the branch circuit disconnecting means.
Let me make sure what you are saying is what I understand...this is fed by a single service drop or lateral into, i suppose, a metal wireway (trough), or a CT cabinet (more likely), then to two disconnects, then back into another metal (or nonmetallic) wireway on the load side of the two disconnects, then to your branch circuit disconnecting means in the same building and to the same tennant? If this is the case then I don't think there is any reason that you cannot do this according to the NEC.
Someone correct me if I am wrong.
