Can you document that? My subpanel has room for 16 breakers (I am using 7
of them) but nowhere for a main disconnect.
I don't know why you would even want a main disconnect; doesn't the breaker
in main panel do that?


A subpanel *in a separate building* is treated like a service entrance.
Service entrances must have 6 or fewer switches to totally disconnect the
power to the building. If your subpanel is in the same building as the
service panel, this (NEC) rule doesn't apply. I don't know about the CEC.
