Derating
In a multi-gang installation, several dimmers are grouped in one horizontal wall box.
When this is the case, the inner heat sink section is removed to permit the installation
of a one-piece multi-gang wallplate. Removing the heat sink reduces the current
carrying capability of the dimmers due to reduced heat dissipation. The following
table provides the derating information for this application.
No Heat Sink Removed
– Single Unit
1000 W (800 W)
1000 VA / 750 W
(800 VA / 600 W)
For additional installation information, refer to the CLW-DIM, DIMS & SLVD
Installation Guide (Doc. 5995).
