Electrical – Need help wiring new dimmer

dimmer-switchelectricallighting

I'm trying to wire a new Legrand Adorne Softap dimmer without any luck. It's replacing a Legrand Adorne paddle dimmer which uses the HOT and 1-POLE connections on the back of the dimmer. The new dimmer requires an additional neutral wire to be connected to WHITE on the dimmer.

This is in a 5-gang box with a few other switches. From the feed coming into the box from the light, there is a black, white and ground. On the old dimmer, black from the feed was going to 1-POLE, while another black wire was connected to HOT which is pigtailed to a red wire from another feed. The white wire from the feed is connected to 3 other white wires in the box and capped off.

I attempted to move the wiring as it was to the new dimmer, and take the white wire from the feed and connect it to WHITE on the dimmer. After snapping it into the frame, I can't get it to come on at all. Does it sounds like this dimmer won't work because I don't have 3 wires from the feed itself? Thanks.

Switches from left to right:

  1. 3 way switch for kitchen light
  2. 3 way switch for another kitchen light
  3. New dimmer for living room light
  4. Existing dimmer for living room light
  5. Fan switch

Your problem is that the white wire that is connected to the new dimmer never actually connects to neutral -- it simply connects to the load. You'll need a white pigtail and a new wirenut to fix this.

Turn the power off at the breaker. Undo the existing wirenut for the white wires, and undo the white wire from the new dimmer. Twist one end of the white pigtail and the white wire that was undone from the new dimmer with the existing bundle of white wires, and put the new wirenut on. Attach the other end of the pigtail to the new dimmer and put everything back together, then turn the power back on and enjoy your new dimmer!
