700.10(B)5 requires that Emergency be separated from all other branches. The NECH shows as an example E separated from LRS (legally required standby) and separated from OS (Optional Standby). So 700, 701 and 702 are all isolated from each other.
I have a situation where my generator will have LRS and OS. Emergency in this particular building is going to be via Emergency Battery Units as sanctioned by the inspector. I don't see that Article 701 has anything similar to 700.10(B)5 and therefore would conclude that I can use a distribution panelboard for my 701 and 702 circuit breakers. i.e. I don't need the isolation I would need if I had an Article 700 ATS.
Do you agree?
