I just bought a wall timer to replace a three-way switch. The wall timer comes with three wires, one for the common screw wire, and the other two are for the travelers, with no place for a ground wire. When I took out the three-way switch it had the common and the two travelers that I needed and it also has the ground wire.
My question is, where do I put or what should I do with the ground in this situation?
I called the manufacturer and the guy said that "a ground is not needed in this situation and that I should just tape it off". Is that what I should be doing?
Here's a picture of the back of the timer.
