Power -> switch 2 -> switch 1 -> fixture.Note: Major changes to original answer, now that OP posted a second picture. But this smart switch needs to connect to both hot and switched hot, and the ordinary 3-way switch needs to connect to hot. Specifically, typical configuration is that one of the 3-way switches will connect to two travelers and hot, and the other to two travelers and switched hot. This is almost certainly doable, since you have the sometimes elusive neutral available in the box. Bottom Right = Load, also known as 'switched hot'.Top Right = Hot (note, this must be true hot, not 'switched hot').Top Left = Neutral (white, connected to the existing white bundle).But assuming you are replacing one 3-way switch with the dimmer and the other one is staying the same, you wire according to Two Location Control Using a 3-Way Switch. There is an accessory switch available to let you dim at both locations.

A smart switch doesn't necessarily need two travelers, and this one doesn't. This one appears to have 3 white wires bundled together.Īn ordinary 3-way switch uses two travelers. I can out the dimmer on this one, whatever is easier. Looks to be wired slightly differently than the one I was installing the dimmer on. ThanksįYI - this is an Eaton WFD30 smart universal dimmer.Įdit: In the pic, the 2 white wires were bundled together and capped (assume they are both neutrals), the black and red are travelers and the other white with the black tape was the 'hot' wire.Įdit 2: Added a pic of the other outlet. There are 2 spots for neutral wires, but they are bundled together in the outlet. So I'm a bit confused here - I have 2 traveler wires but only one spot on the new switch for one. According to the instructions, the top left is 'neutral', the bottom left is for a traveler, the top right is for the hot wire, and the bottom right is for another neutral wire. Now, the new dimmer switch has the green screw (for the ground wire), and then 2 screws on each side. I also noticed 2 neutral wires (both white) that were bundled together and capped. The old switch had 2 traveler wires connected to it (black and red), the ground wire, and the 'hot' wire.

Replacing an old 3 way switch with a new dimmer 3 way switch.
