Do you need a main breaker at a Sub panel on an apt.

I have reviewed 230.72 (c) and 240.24 (B) (1) & (2) but it seems to be a gray area when it talks about being "under continuous building management supervision". How would you know that? Most electrical rooms are locked, and, in some places, management does not work weekends.

That's what I thought but I wanted to double check. I guess it is good to have a main breaker for tenant's convenience, but it can definitely become more expensive.

You could submit a clarifying Public Input to the next code cycle, the deadline is soon.

This not a clear rule, but to me the "continuous building management" requires management onsite 24/7.
