Ganging & Derating

Planning a Custom Architectural Multi-gang

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)

	Number of Small Controls							Example wallbox arrangement required for gang of 4 small controls, side sections intact:
Number of Large Controls	0	1	2	3	4	5	6
0	0	1	1+1*	4	4+1*	7	7+1*
1	1	3	5	6	8	9	11
2	4	6	7	9	10	12	13
3	6	8	10	11	13	14	16
4	9	11	12	14	15	17	18
*Note: When ganging an even number of small controls with no side sections removed, use wallboxes with tapped ears as shown. 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.

Wallboxes Required - All inside sections removed

	Number of Small Controls							When removing side sections, remove only inner side sections. Do not remove side sections on outer ends of the gang.
Number of Large Controls	0	1	2	3	4	5	6
0	0	1	2	3	4	5	6
1	1	3	4	5	6	7	8
2	3	5	6	7	8	9	10
3	5	7	8	9	10	11	12
4	7	9	10	11	12	13	13

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.
