Hi, and thanks for taking the time to look at my post.
I am trying to install a GE Z-Wave 12729 Dimmer and 12728 Add-on in a 3 way to control a circuit that contains 7 recessed cans with LED lights.
This circuit is currently controlled by 2 dumb 3-way switches.
Pictures of both boxes and all box wiring: https://photos.app.goo.gl/zcEXdLfAQHbkYidI2
Dumb switch wiring:
Main box: 120V line to common terminal, 1 red traveler, and 1 white wire to the opposing terminals on the dumb 3-way switch.
Secondary box: Red and White from the main box (conductivity tested with a 9V battery). 1 black to the common terminal.
Unlike several other successful GE 3-way installs in my house (including another one in the same main box), the main box does not currently have a Load connection for the 12729 and I’m unsure how to wire the smart switches as a result.
However, I do note that there are 2 black wires tied together in the main box.
Hopefully, the pictures are worth more than the text of my post and someone out there recognizes this wiring layout. If I knew what this layout were called, I could search here more effectively, but I did read the 3-way FAQ and search before posting.
Thanks and please let me know if there is any other diagnostic info I can provide.
[Edit] Thanks everyone: it was line and load in same box and easily resolved by Michael’s suggestion and made perfectly clear by Ryan’s diagram.
