I will be adding a ground to an existing 3-wire setup in oder to make it safe and code-complaint. Will the new bare Cu ground wire use the same receptacle knockout (bottom) as the Al jacketed 3-wire, or will it have to be clamped from the back via the other knockout?

enter image description here Is it OK to have exposed bare ground (4th-wire) for a short run behind/under the range? enter image description here

  • I have a feeling there will be only 1 clamp provided per receptacle.What type of clamp do I need to get for a bare #8 or #6 ground wire
