Absolutely, yes, treat it like it were a subpanel down the hall.
For me, Thanksgiving 2005 was spent at a 24/7 data center, where half the building was down. The cubicles sounded like a nature preserve, with all the desk-site UPS's chirping.
The building had, I was later told, a history of all manner of power quality issues. In any event, many circuits in this building were acting up. To complicate matters, exactly which circuits were acting up seemed to keep changing.
BTW, did I tell you this building was located directly UNDER the interstate?
The electric room had a bank of three panels, set next to each other with only short nipples connecting them. The original installation had been done by a man who was instrumental in adding major parts of Article 250 to the NEC.
The first clue - more of a random thought - came when it was noticed that the neutral bars in all of the panels had green screws in them. This led to my noticint that the panels did NOT have any neutral wires tying them together. That is, the metal cases and their connecting nipples were the neutrals.
Well, that just didn't seem right. With everything down anyway, I took the opportunity to run a large neutral from the 'main' buss to each of the other busses.
Guess what happend next ....
Yup. Problem disappeared. ALL of the malfunctioning circuits suddenly had the purest quality power they'd seen in decades.
I can only theorize that, at some point, the bonding between the panels was less than perfect. Maybe a little paint, a little rust, a little vibration (remember that freeway overhead?) all conspired to make for a poor connection somewhere.
I learned something that day.
I also got home, just in time to see my 6-month old kitten try to 'catch' the dinner turkey ... but that's a story for another day
