Where in the code does it say that you can connect the emergency lights/ballast in a room where the lights are controlled by a dimmer rack to a breaker not connected to the dimming system?

701.10(G) requires that unit type EMG lighting to be connected to the same circuit feeding the general lighting of the room they protect, this is to be ahead of any switching and or control.
The reason is you don't want the breaker for the lighting to trip and leave no light for the room.
All though this makes no sense as for other types of systems it perfectly ok:?
Beside that, if the EMG lighting is controlled by the swich (and the connection after the switch or control) the EMG lighting will be on when the switch is off.

That is why I put in my post that you have to connect the EMG lighting ahead of any switchs that control the lighting, but unit type EMG lighting is supposed to be on the same circuit (branch circuit) that feeds the switch that controls the room lighting, most know if you turn off the power to a EMG lighting unit it will come on, I at least hope they know.
