I replaced a single box switch to a PD-6ANS in an exercise room with 30 fluorescent tubs, the lights were replaced with LED equivalents. I did the math and with they should only be using about 500w, and this switch is rated for 700w. The switch runs very warm, makes me a bit nervous. It operates, but the previous switch was not warm in anyway. Is there something else I should check? Is it normal for them to get warm/hot? It's more of the screw on the face plate the get really hot. Any suggestions would be appreciated? Did I wire it wrong? There is a group and a neutral, etc. JUST FYI, Before I switched out the bulbs it was very warm, but as I took the old bulbs out it got cooler, but as I added the new LED bulbs, it got warmer again.Thanks in advance.
