What is the deal with putting several dimmers in one box? Why do they get so hot and what can I do to fix the problem?

LUTRON DIMMER CONTROLS must be DERATED WHEN GANGED to accomodate the combined heat load. LUTRON ELECTRONICS does a good job of explaining the use of multiple dimmers behind one switch plate.

It is very important that you understand how to properly gang dimmers and the consequences of a poor installation. All DIMMER CONTROLS get hot and they dissipate the heat by using the aluminum heat sink on the front of the dimmer. When you gang them you have to remove a portion of the aluminum heat sink which causes the temperature to rise and is multiplied by each dimmer you install. You can rearrange the dimmers in the box by separating them with switches in a multi gang box or relocate the dimmer to the other end of a three way system.
