Multigang Installation
Side Sections Removed, Derating Required
1. Determine the number of large and small controls
required.
When ganging any combination of small and large controls,
place all small controls on one end of the gang and all large
controls on the other. Use the chart below to determine the
size and maximum capacity of each control.
Multigang Installations:
No Side Sections Removed,
No Derating Required
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.
Note: N-603P and N-1003P are listed as “small” controls. N-1503P and
N-2003P are listed as “large” controls.
Wallbox Requirement Chart
Ganging and Special Wallplates:
Dimmers can be ganged with other 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 controls to fit existing wallboxes; however,
this will require lamp derating.
Note: Masonry Multigang Wallboxes are recommended for neater
installations.
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) chase nipple is recommended as a spacer between the
wallboxes.
