In this article, I have covered the standard CNC milling parts, tools commonly used with the machine, factors affecting the cost of a CNC mill, and how CNC machining works. I hope that you’ve got the basics of this important manufacturing process.
Pay close attention - if the ears "bottom out" on the metal of the box, you do not need that ground wire. If they bottom-out against drywall, you need a ground. Unrelated, one more tip on the device-mounting screws. Each NM cable (and other types) must now have a ground wire. In the US, most of these cables have a bare copper ground wire. Sometimes you will see ground wires with green insulation, and occasionally on fixtures you .
In Canada, I can't think of a cable off the top of my head that doesn't have a bare copper bond wire in it. And even if the metal box is fed by metallic conduit, I still make a . You'll want to use either bare copper, or green insulated wire. Solid or stranded makes no difference, as long as it's the proper size. Some will argue one way or the other about connecting solid to stranded, stranded to . There is no prohibition in the NEC to installing a bare copper EGC in a steel conduit. Take a look at 250.118(1) this section specifically permits a bare copper conductor to .Nec and cec allow you to run a separate ground wire if you need it, and you can connect it basically anywhere that bonds to the panel's grounding conductor. eg if your panel runs its big thick braided egc to the cold water intake pipe (like my .
The ground wire is a solid, bare copper wire. The cable is NM of some type, although I didn't see what type exactly and I'm at work so I can't check until I get home. The .
If you have romex in the box with ground coming into a metal box, it's a requirement to also ground the box. You would pigtail your bare copper with (2) wires, one to the box and one to . Several Journeymen have stated that if you run metal conduit, the conduit is considered grounded, thus a ground screw in every j-box is not required (the same answer .
Correct. Since you have a metal box they should be grounded, or else the box could conduct electricity if a hot wire touches it, and even have the plate screws be conductive and be a .

In Canada, I can't think of a cable off the top of my head that doesn't have a bare copper bond wire in it. And even if the metal box is fed by metallic conduit, I still make a ground jumper and bond the box to the bonding screw on the device. I guess I'm still stuck in the pre-self grounding days. And that doesn't bother me either.
You'll want to use either bare copper, or green insulated wire. Solid or stranded makes no difference, as long as it's the proper size. Some will argue one way or the other about connecting solid to stranded, stranded to stranded, solid to solid, stranded to screw terminals, solid to screw terminals, etc. There is no prohibition in the NEC to installing a bare copper EGC in a steel conduit. Take a look at 250.118(1) this section specifically permits a bare copper conductor to be used as an EGC. Chris
Nec and cec allow you to run a separate ground wire if you need it, and you can connect it basically anywhere that bonds to the panel's grounding conductor. eg if your panel runs its big thick braided egc to the cold water intake pipe (like my house), you can connect a ground wire (bare copper of the same gauge or thicker than the circuit it's . The ground wire is a solid, bare copper wire. The cable is NM of some type, although I didn't see what type exactly and I'm at work so I can't check until I get home. The NM wire has a black wire, a white wire (which has red electrical tape around it), and a bare ground.
If it's possible, I would rather not using ground wire connect to the receptacle because it's easier to do and save space in the box. In addition, I don't have extra green ground wire left. If I need to add pigtail, could I use bare copper wire? If you have romex in the box with ground coming into a metal box, it's a requirement to also ground the box. You would pigtail your bare copper with (2) wires, one to the box and one to the outlet. Upon opening junction boxes in my basement I found the bare ground wires connected to the metal box itself. Is this proper, or should the be pigtailed inside the box? Or is it just a matter of preference? I have googled this question and just kept getting directed to recepticle boxes. Both!
