if you don ground an junction box If new fixture has a ground wire, then just connect grounds together with wire nuts/wagos, plus to the screw in the box. Quite a few light fixtures . Ga. is different from inches, there is no conversion formula. Even when the non-ferrous metal plate and the steel plate are the same Ga., the thickness is actually different. You can find the gauge to mm / inch conversion for sheet metal by the chart below.

In steel between 0.5 and 0.8 in. thick, grade 350 and 400 may have a minimum bend radius of 2.5 times the material thickness when transverse bending, while longitudinal bending may require a minimum bend radius that’s .
If new fixture has a ground wire, then just connect grounds together with wire nuts/wagos, plus to the screw in the box. Quite a few light fixtures . Don't ground to the electrical box.

Where circuit conductors are spliced within a box, or terminated on equipment within or supported by a box, any equipment grounding conductor(s) associated with those . Since the box is grounded through the conduit (which is as good a ground conductor as any), you don't even have to terminate the ground wire to the box as long as the Z-wave switch has a metal yoke that contacts the box, although you can get a grounding screw (any 10-32 machine screw will do in a pinch), screw it into the back of the box (there .
Now, if the junction boxes are indeed grounded (e.g. via metal conduit as discussed above), here's how you can ground receps. #1: Run a wire to a ground clip or screw (often there's a hole tapped for a #10-32 screw in the back of the steel box). Or #2: Remember how I said you can ground the switch through the mounting screws? . You don't need .

WRT the hope that the house ground wire is actually grounded - the answer is it should be, but you can't be sure without testing or tracing the line. Case in point - I owned a house where all the ground wires were properly connected in the upstairs apartment, the ground from the breaker box ran to the plumbing stack - and the stack switched from metal to pvc half way . The box has a GFCI outlet. I then go a few feet horizontally to another junction box with a duplex outlet; repeating to the next box and the next. I have my ground wire from the breaker box, connected to the ground screw on my junction box. This is also pig-tailed to the GFCI outlet, and then to another ground wire which leads to the next box.
The metal ones have a ground wire connection which makes sense. The part that I don't fully know is, The incoming conduit includes a ground wire. So I have positive, neutral, and ground. I don't know who installed this prior to moving into the house but I noticed that that ground connection in the junction box is not being used.
The photo shows 2 ground wires under the screw so the box is grounded, many light fixtures have a metal strap that when connected to the metal box is the ground path. The green screw on the strap is used to ground the fixture. To make a proper ground the ground in the cable with the hot should go under the screw if long enough.I had the same problem, Ring tech support was absolutely useless and their only answer was "hire an electrician". People don't seem to realize that its not a matter of simply replacing the rectangular box with a round box from where ever when the rectangular box is mounted in brick and mortar, not particle board siding.Box adapters are used in this image as the connection fittings. For a water tight connection, you can also use male terminal adapters and washers for a watertight application. 3. Create a trench for the conduit and junction box according to all electrical codes, and place the junction box and the conduit in the ground. 4.
What Happens if You Don’t Ground a Ceiling Fan? In the electrical circuit, if the ground is not connected to neutral, or the ground within the system is not sufficiently grounded to the earth itself, there will exist no path back to the power source. . Firstly, it is important to ensure that the junction box in the ceiling is rated .You can use the existing junction box that you have there for the cable, assuming that junction box is for another circuit, you can either add another receptacle since it is a square box or break both taps in the existing receptacle and one half is one circuit and the other half is the other circuit. The junction box can be either plastic or metal.Neutrals are current carrying conductors. On a 120-volt circuit if you have 2 amps on the hot, you should have 2 amps on the neutral. But if you bond that neutral to ground anywhere but the source you'll have some of that current finding creative ways to get home. One of them could be through you. Install GFCIs and be done with it

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 . From there I will run the Romex into a junction box. 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 .Deep inside the junction box is a bare copper wire (presumably ground). It was not attached to anything with the previous light fixture. My understanding is that all ground wires need to be connected. I am just not sure exactly where/in what order they should connect, or where they connect to the green ground screw on the mounting piece.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.
What happens if the ground wire is not connected?If the ground wire is not connected to an electrical circuit, it can have several consequences, both in term.
I know this will be dismissed as nonsense, but why install the boxes if you dont need them. If you are doing any renovations involving permits, I would install the boxes. If you decide to install the boxes just use round or octagonal type. You must have a way to secure them to the stud or the wall behind them.I don’t know if it works in this case but when a cable gets shorted due to screw nails or in this case shorted out due to insulation meltdown you can do a resistance test from both ends of the cable and work out where about the problem is ofcourse it’s more accurate with a straight run as cables running to buried boxes may not be a straight run, so if you have an issue between two .You must connect your wires inside a junction box. If you don’t have a junction box, you should add one before connecting the cables. In other words, if you want to understand your electrical system, you should look inside the junction box. You will find all the important wires inside this box, including the ground wire.Hi folks. Replacing a few lighting fixtures around the house (built '08) - if I ground the fixture directly to the ground wire in the box (plastic boxes) with a wire nut, do I also have to ground the fixture to the green ground screw on the mounting bracket (wrap it a couple times before grounding to the uninsulated wire in the box?), Or is just grounding to the wire sufficient?
That would then be inserted into the knockout opening in the termination box on the dishwasher. A listed connector would create the ground path from the armor to the box which is connected to the ground of the dishwasher. That cable looks pretty crusty FYI. Not sure you’d get a good path to ground through that. I’d probably replace that cable.
