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 |
Width |
| |
Side Sections Intact |
One Side Removed |

| Small |
2 3/4" |
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

Nova).
