I’ve tried to install the electrical wire for the GE dimmer the same way as the older light switch by keeping the hook shape for the electrical wire and was having a difficult time fitting it in. The screw doesn’t come out all the way and it just seems awkward.
It just so odd that it’s difficult to do, so I then searched online to see if I was doing this incorrectly. I found out that the GE Z-wave light switches were made from Jasco and they were licensed it out to GE. From there I was able to find some videos regarding their GE-Zwave products which are different then the one’s provided from Lowe’s. http://www.jascoproducts.com/support/video/z-wave-videos.asp
The video titled “GE Z-Wave on/off Switch” was most useful about 57 seconds into the video. From there you can see that they install the wire not by bending it like a hook but keeping it straight.
Just to show you how the traditional light switch wiring looks like while it’s hooked around the screw and tighten.
While the GE Z-Wave light switch requires the wire to be straight and be placed through the hole in the back then tighten with the screw.
