I'm replacing an old ceiling light with chain with a light with outlet attachment in a grounded metal box. Do I need to ground the fixture since I have a 3 prong outlet, or since box is grounded I don't need to?

  • If it is a 3 wire fixture it should be grounded, if you are installing the wires to the light the frame should be grounded. – Ed Beal Jan 2 '16 at 18:53

You should ground to the box, the light, and the outlet if they are metal and you are able, i.e. it has a ground wire or ground screw.

There is no harm in pigtailing off a short piece of wire to ground everything you can; it'd be worth it if anything were to ever short out.

And since I'm unsure by your post, I'll clarify this.. just because an outlet has 3 prongs does that mean that it is grounded. You still have to run a ground wire to it to make it grounded. Same concept as that the receptacle wouldn't be powered until a hot wire were ran to it.

Yep. Look for the Green Screw & run a 6" (or more) pigtail of wire from it to the box's ground.

  • He may not have a ground screw on his fixture, but a ground pigtail instead. – ThreePhaseEel Jan 3 '16 at 7:13
