I have a timer switch (see photo 1) that has No Grounding Screw and ** No Grounding Wire** protruding from it. It is to be installed into a plastic gang box and replace a switch which is currently grounded by a wire.

The power source for this switch comes from a GFCI circuit.

Should I ground the timer switch by wrapping it around the screw attached to the yoke like the second photo.

  • Does the labeling or instructions authorize installation in a plastic box, is it silent on the matter, or does it have language warning "metal boxes only"? Feb 25, 2019 at 23:34

    It looks to be silent. Instructions

  • This is a honeywell switch it seems, and from what I have read online, it is suggested to ground thru the screw as you have posted in your second image, if it is not a metal box.

  • Looking at the docs this looks like a legit item. Some purchases from Amazon are okay. Feb 26, 2019 at 6:27

I called the company, they didn't seem very knowledgeable. Since the yoke is metal and would be grounded if installed in a metal box. I went ahead and grounded it as between between the box and yoke with the top screw.

It looks like it's a class II product, so it doesn't need grounding.
