Doing a job in a commercial building with a 600 amp service section that has 2 - 100 amp panels and 1 - 200 amp panel there already. They are moving in machines and work tables I'll put drops in for.
I will probably need to add another 200 amp panel. Would that be considered a sub-panel? Do I need to isolate the neutrals and grounds in it? The other panels are not the bolt-in type breakers. I believe snap in breakers are ok for a commercial biulding, correct?
