| Ganging
and Derating Information |
WHAT IS GANGING ?
Ganging is the mounting of two or more controls
side-by-side in a series of connected wallboxes.
WHAT IS A SIDE SECTION/FIN BREAKOFF?
A scored section along each side of the mounting
plate/fin designed to be removed to facilitate ganging.
Ganging and Derating for Lutron
Wallbox Dimmers
Vareo, Nova T*, Nova, Centurion - may be ganged
without removing the side sections - no derating required. Side
sections can be removed to save space or have ganged units fit
into existing wallboxes - derating required (side sections must
be removed if using VWP Vareo wallplates for Vareo wallplates
for Vareo dimmers or tap switches).
Lumea2, Maestro, Diva, Skylark, Ariadni, Faedra,
Glyder, Rotary - must remove side sections to gang - derating
required.
Athena - no removable side sections - no derating
required when ganged.
WHAT IS DERATING?
The reduction of the maximum capacity (load)
a dimmer can reliably handle when the side sections (fins) are
removed.
| Planning
a Multigang Installation |
STEP 1
Determine if the side sections are to be removed
or to remain intact (applicable to Vareo, NovaT*, Nova, Centurion).
Consider: width of application, load, number
of wallboxes required, product type and side section breakoff
options
Control Widths (for determining
width of a ganged installation)
| Control Size |

2 1/4" |
1 3/4" |
| Large |
4 1/2" |
4 1/8" |
3 5/8" |
- All Vareo models are considered "small"
controls
- For control sizes of Nova T* and Nova dimmers:
- 600W and 1000W models are "small"
controls
- 1500W and 2000W models are "large"
controls
- For control sizes of Centurion and Athena
dimmers
- 600W and 1000W models are "small"
controls
- 1500W and 2000W models are "large"
controls
- All Lumea2, Maestro, Diva, Ariadni, Faedra,
Glyder and Rotary models are considered "small" controls
STEP 2
Use the capacity derating charts to
determine maximum permissible loads for each control in the installation
if side sections will be removed.
STEP 3
Determine number of wallboxes required and
plan control placements in gang (see charts below):

*Note: When ganging an even number
of small controls with no side sections removed, use wallboxes
with tapped ears as shown below. Do not use plastic rings or gangbox
covers. Space an additional wallbox 3/4" apart from the other
wallbox(es). A 3/4" chase nipple is recommended as a spacer
between the wallboxes.
Example: wallbox arrangement
required for gang of 4 small controls, side sections intact:
Assembling the Controls
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 center
and offset mounting holes as necessary.

Removing Inner Side Sections
When removing side sections, remove only inner
side sections. Do not remove side sections on outer ends of the
gang.
Assembling the Controls
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 center
and offset mounting holes as necessary.
STEP 4
Determine the multigang wallplate requirements
(Vareo, NovaT*, and Nova).
