I installed a new chandelier and dimmer. The chandelier houses 24 40W bulbs. So, at the recommendation of the lighting salesman and after doing the math, I got a 1000W dimmer. The light works fine. However, the dimmer gets hot to the touch. Very hot! I don't think that this should happen so I exchanged the dimmer thinking that something might be wrong with the first one that I bought. Unfortunately, the dimmer still gets hot. What could be causing this? What can be done to fix the situation?
