Learn how to connect equipment grounding conductors to receptacles and keep their continuity in boxes. Sometimes if I have a 3 or 4-gang plastic nail-on switch box that has a bunch of NM cables, when I'm making up the box rather than using a big blue wire-nut for my grounds I'll separate the grounds into 2 groups and use red/tan wirenuts instead, especially if there's 2 circuits in the box. I can. In a metal box, a wire type equipment grounding conductor can be attached to the box with a ground screw or clip and terminated to the switch or receptacle in the box. Connecting the receptacle grounding terminal to the metal box ensures an effective ground-fault current path. The basic rule achieves this through an equipment grounding jumper; four exceptions. I'm using metal box has two ground screws, can I wrap around one ground wire (from supply side) on one of ground screws then connect it to the outlet and connect another ground wire (or two wires ) going to the next box (es) on the secondary ground screw?
