Viperman Posted May 11, 2023 Share Posted May 11, 2023 I hooked a dimmer up to control some lights. I have the black wire to black and it has 125 Volts all the time. white wire is to the white wire, ground is to ground and the red wire is going to the light. It turns on and works perfectly. However when I go to shut it off the LEDs stay on but very dim, and it is still pushing about 52 volts through the red wire. It would seem to me like it should be pushing 0. What am I missing here?

RyanE Posted May 11, 2023 Share Posted May 11, 2023 Many dimmers, even if there's a neutral line, send a very small amount of power through the load, even when the load is "off". With Incandescent or Halogen lights, this is not an issue, since they do not light up with small amounts of power. LEDs can be a different story. The solution is usually to install a small load capacitor in parallel with the LED lights (across the red and white terminals on your dimmer, or across the white and black wires in one of your lighting fixtures). Here's an often recommeded minimum load capacitor, from Lutron: https://www.amazon.com/Lutron-LUT-MLC/dp/B01E9F084E RyanE Quote Link to comment Share on other sites More sharing options...
