Does 600.6 require an external disconnect switch for a 12 volt, class 2 LED sign? The driver is inside the building and the sign is only fed with a two wire, class 2 cable.
If a disconnect is required, do you agree that it would have to disconnect the branch circuit(line side of driver)? It seems rather silly to install a disconnect for the two 12 volt class 2 wires.
I'm specifically asking about the requirements in 600.6 and 600.6(A)(1). Of course a disconnect switch would be required for the controller. Most of the time in these office or warehouse type buildings, the controller is next to the panel. But I'm not asking if a disconnect switch for the controller.
Is a disconnect required for the LED sign, wether in site or out of site with conditions per 600.6(A)(1)?
