Grounding of the casing of the surface-mounted electrical box
Connecting the receptacle grounding terminal to the metal box ensures an effective ground-fault current path. Learn how to connect equipment grounding conductors to receptacles and keep their continuity in boxes. The basic rule achieves this through an equipment grounding jumper; four exceptions. An equipment grounding conductor passing through the box without a splice is not required to be joined inside the box to others that are spliced in the box. Not all boxes are metal or provide. The requirements apply to switches of all types such as snap switches, dimmer switches, circuit breakers, fused and non-fused disconnects, and automatic timer switches. When using metal boxes for duplex outlets, are you required to ground the metal box FIRST before the outlet itself? I have been told that if you ground to the outlet (the outlet ground screw), the entire thing is grounded when you screw the outlet into the metal box.
