I have a slide on the side 1000 watt dimmer with a connected load of 580 watts. The dimmer heats up hot to the touch. The dimmer in the same box for different lights is a 600 watt slide on side connected to 260 watts. does not get hot only warm that is normal. Anybody have any ideas why this is getting so hot?. I originally had a 600 watt in place of the 1000 watt. It got just as hot. Also the other dimmer is off when this happens. Thanks.
