I have fried 2 of these smart Dimmers now.
First one, I had all wires except ground connected. I inserted ground wire the started tightening the screw. When the screw was close to tight, Sparks flew & the switch was fried.
Second one, in a 3-way writing setup. I had both the dimmer switch & the add-on switch connected and working hanging out of the wall. I screwed in the add-on with no issues. As I went to screw in the dimmer, I applied some pressure because of the crowded box and Sparks flew and the switch was fried. I think the Sparks came from the area of the ground terminal.
Anyone else having the same issues? Is the ground terminal very close to the load terminal & too much pressure will cause it to Arc & fry?
Thanks in advance for any help anyone can provide,
