not a test question...and this is with a non-metalic box

then you need to attach the grounding wire to the screw on the switch. 404.9b as iwire stated

404.9B is pretty similar to the article i mentioned.

Yes, they are close. :smile:

Although with 404.9(B) we lose the "direct metal to metal contact between the yoke and the box" requirement that is present in 250.146.
