1.
Determine the number of large and small controls
required.
When ganging any combination of small and large controls,
place a small control on one extreme end of the gang, and a
large control at the other end of the gang. Use the chart
below to find your wallbox requirements.
Ganging and Special Wallplates
Dimmers can be ganged with the entire family of Nova controls.
FOR NEW CONSTRUCTION we suggest installing the dimmers
without breaking or removing the side sections. This will insure
that the control can be loaded to its full-rated capacity (no
derating). Follow the instructions below to install your controls with
NO SIDE SECTIONS REMOVED. For a retrofit installation, side
sections can be removed from the controls to fit existing
wallboxes; however, this will require load derating.
To maintain a smooth, clean installation, one-piece Lutron Multi-
Gang Wallplates are available. Custom finishes, engraving and
silkscreening are available upon request.
Note: NLV-603P, NLV-1003P are listed as “small” controls.
NLV-1503P, NLV-2003P are listed as “large” controls.
Note: When ganging an even number of small controls with no
side sections removed, do not use plaster rings or gangbox
covers. Space an additional wallbox 3/4" (19 mm) apart from the
other wallbox(es). A 3/4" (19 mm) close nipple is recommended
as a spacer between the wallboxes.
Note: Masonry Multi-Gang Wallboxes are recommended for
neater installations.
2. Assemble the controls.
Use the center or offset mounting holes as needed. Allow a
1/32" (0.8 mm) space between controls for ease in attaching
the wallplate.
