What to do with ground wire

I am replacing my on/off wall switch with a timer that will control the lights that come on on my porch. One of the wires is the ground (green) wire. There is no place to attach the green wire, the box is plastic. Should I just cap it with a wire nut or is there another place to attach it?

So you are saying there is no ground inside that plastic box ?
That's pretty strange for as long as plastic boxes have been in use there has been grounded cable.

Are there grounding conductors in the box? Do the instructions say the switch must be grounded?

I agree with the others. Unless your house was built in the 60's, there should be a grounding wire in the cable entering the box. Now, that isn't to say some jack leg electrician didn't cut it off when installing the switch, but it should be there.

I guess someone should mention that the ground wire in the box is likely bare, not green. If you have a bare wire, attach the green wire to that.

NM cable without a grounding conductor was available up into the very early '80s, but it shouldn't have been used where a ground was required in new construction. Perhaps there were no local codes or inspections where this house was built and a hack electrician used what was cheapest knowing it would never be inspected.
