One of my venues has about a 10x10 room with 2 48-channel (I think) CD-80 racks in it, mostly fully populated.
It's been awhile since I've been in the room, but I think the CBs are inside that room -- and I think code *requires* the disconnecting means to be "in sight of" the devices anyway, right?
So how do you disconnect such a thing if there is, say, a fire, if you *can't go in the room*... and the next upstream is in the power room, two floors and at least 90 seconds of a flat run away?
How would you engineer such a thing, power people? A switch disconnect upstream the CB, in the adjacent room (which is on the other side of a 2H fire door)?
