Note: When mounting in a multiple-ganged junction box, SwitchLinc
Dimmer is de-rated for 200-watts less for each immediately adjacent
dimmer installed. For example, 600W load control becomes 400W with
another dimmer to the immediate right or left. Use a triple-gang box with
a mechanical switch in the center to avoid de-rating.
