Using some sort of ginormous wire nut to . I have read several articles that say its acceptable to use the screw that comes with the metal box for grounding. The two silver ones usually used to attach a fixture. As long as that screw is only used for that purpose and none other. Now the NEC says you must use a green hexagonal screw as the grounding screw for the metal box.
Metal conduit and junction boxes outside MUST be grounded for the same reason even low voltage cable must be, it gives static from things like wind a place to go instead of building up and creating a lightning rod (which is a misnomer as a real lightning rod prevents the strike by giving the static an earth/ground path that’s safe). Well a box is a box pull box or junction box . If we use a pull box with say large feeders the largest ground in any of the raceways will be that ground bonded to that box in that pull box or junction box with a pass thur mechanical lug to case .

Oh in that case its a yes. The ground wire gets attached to all boxes, devices, fixtures, and so on. Basically, if its metal and an electrical device it needs a ground. But the ground does not need to be dedicated, you can just wrap it around the ground screw in the box then attach it to the ground screw on the outlet.Is there any issue in grounding on old junction box that is not grounded. This junction box has a switch loop in it; not sure if that is why they did not ground it. I have attached below diagram and photo of connections if that helps. I am just trying to figure out why it was never grounded in the first place and if there is some reason to not .
Could I use something like an Eaton ground bar in this junction box (Picture attached) if I scrape the paint behind the ground bar, scrape the paint on the opposite side, through nut and bolt it, and run a jumper to the green screw pictured in the box. The largest circuit is 20 amps, so I think I could use a #12 jumper.Sometimes when ceiling boxes are roughed in, they use x/3 with ground cable so that they can supply 1 switched hot, 1 neural, 1 hot/switched hot, and 1 ground to the ceiling box.. This allows a ceiling fan to be installed in such a way that the fan can be controlled either by a separate switch, or using only the attached pull chain.

Especially if you are using the metal junction box as a self-made "extension cord" because if that box comes into contact with moisture getting an electric shock is . I'm moving a clothes dryer about 7 feet. The existing Cable is 8-3 (red, black & white) with no ground wire. I wanted to use a metal junction box but I need to ground it. The dryer is grounded by using a jumper wire from the chassis to the neutral. Any reason I can't use that same method to ground the metal junction box? Thanks Inside the junction box I will strip off the outer Romex, exposing the 3 THHN wires inside of it (hot, neutral and ground). The hot and neutral wires will not be perturbed at all and will be sent down a PVC conduit all the way to the junction box housing the outlet, where they will be attached to the outlet. If circuit conductors are spliced within a box or terminated on equipment within or supported by a box, all equipment grounding conductor(s) associated with any of those circuit conductors shall be connected within the box or to the box with devices suitable for the use in accordance with 250.8 and 250.148(A) through (E).

And you would ground metal junction boxes and metal electrical boxes along the way. The problem with old electric panels is they may not have a ground bar. Or the ground connection may have been cut/disconnected. Or the panel may be grounded to a water pipe and someone has since replaced the main metal water pipe with plastic water pipe (no . If there truly is no 10-32 tapped hole in the box, then I'd remove the grounding wires from the box mounting screws, nut them to a pair of 12AWG bare pigtails, and land one pigtail on the GFCI's grounding screw and the other on a self-drilling grounding screw (Garvin GSST or equivalent, note that it must be 10-32 UNF to meet NEC 250.6, coarse .
If you have a junction box with several runs, some of which are spliced, and other that are "pass-through" with their own grounds, does every grounding wire that passes through that box need to be broken and spliced? I read 314.4 which was relatively vague, and 314.40 (D) which also was not specific. Under current/recent NEC rules I believe the grounding pigtail is required, so that the outlet will still be grounded even if it's not screwed to the box [or because the ground pigtail is regarded as a better connection to the box than the mounting screws are, I'm less sure of the intent than that current rules require the pigtail.]. Consider that if they considered the mounting .
The clip holds the ground securely against the inside of the box grounding the box. This was an existing ungrounded metal junction box where the back of the box was flush with a 2x4 and it didn't have the raised section for grounding that newer boxes have.
