Ganging
Nova T ®switches can be installed in a common gangable wall-
box or a series of interconnected wallboxes for a clean, consolidat-
ed appearance. Controls must be ganged without removing side
sections.
When ganging any combination of small and large controls, place
all small controls at one end of gang, all large controls at other
end. The NT-2WS-AU is a small control.
* Note: When ganging an even number of small controls without
removing side sections, you need an additional wallbox. Use a
chase nipple as a spacer. See figure below.
