A metal box can be mounted to a wood stud/or floating in drywall(old work box) with a ground pigtail and meet code requirements. In my mind , path of least resistance would mean if someone touches the metal box it will go through them to ground. In my mind all boxes should be mounted to metal so path of least resistance isn't a person.If you have a water pipe made of metal, you can use it to ground your outlet. First, turn off the power to the outlet at your breaker box. Then, remove the outlet cover and unscrew the outlet from the electrical box. Next, find the green grounding screw on the outlet and remove it. Finally, screw the green grounding screw into the metal water pipe.
I've been replacing a few light switch in the house. Ran into a small snag. Old house, so there isn't a ground wire in the box for the switch, just the line and load wires. I've connected the new light switch ground wire to the metal box that is holding it, by attaching it to one of the screws that connects to the box. Is it good enough or . I'm attempting to install a smart light switch in an existing light switch box. There's isn't a ground wire I can see, nor does my voltage detector light up when I touch one end to hot and the other to the box. . You have metal conduit connecting metal junction boxes. All of it is ground. The conduit, the boxes, all of it. This is the ideal . The general text of 250.146 says a bonding jumper is required. 250.146(A) says a bonding jumper is not required where the yoke makes a solid connection to the box.The part after that says this provision, i.e. jumper not required, shall not apply unless the box and cover combination is listed as providing satisfactory grounding. If the box was metal, the pigtail would attach to a grounding screw on the box itself and that would effectively ground all of the switches in that box. Edit: as long as you're in there, it would be a good idea to change all of the connections so they are connected to the screw terminals and not the backstab connectors.
Step 5: Grounding the Plastic Electrical Box. Grounding a plastic electrical box is a crucial step to ensure the safety and proper functioning of your electrical system. Follow these steps to effectively ground the plastic electrical box: Prepare the grounding wire: Cut a length of bare copper or green insulated wire to serve as the grounding wire.

Wiring: Electrical wires are used to connect the switches to the electrical devices or lighting fixtures. Mounting Bracket: The box is typically mounted in a wall or ceiling using a metal or plastic bracket. Cover Plate: .
If your receptacle has only two prongs, use a multimeter by placing one lead in the hot port on the receptacle and the other on the metal outlet box or the metal of the plate screw. If the meter reads around 120 V, then the box is grounded. If you don’t get a voltage reading, then the box isn’t grounded. Here are the steps to visually inspect the grounding of an electrical box: Turn off the power: Before conducting any inspection, ensure that the power to the electrical box is turned off to avoid any potential risks of electrical shock. Open the electrical box: Remove the cover plate of the box to access the inner components. Use proper safety .The connecting to a metal box is fine, if the house ground wire is also connected to the box, if you can verify that, then go for it. If you can't, make sure the switch ground is connected to a ground wire within the box. Some boxes are plastic and there are common ground screws since the box itself doesn't conduct electricity.
One of the single pole switch boxes had a single ground (no bundle) that came through into the box and was tucked to the back of the box. . The boxes are plastic and not metal so not a natural ground; . switch if a . 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, .

Assume you have a metal device box, correctly installed with 14/3 cable incoming and a three-way ungrounded light switch installed. Assume that the box is correctly grounded using the ground wire attached to the ground screw of .
There do not seem to be any equiment ground wires emerging from the conduit. This is likely because the box is grounded by means of the metal conduit. In that case, you do not need a ground screw or wire in the box, and in any event adding them will do nothing worthwhile. You should use a "self-grounding" GFCI receptacle. This is covered by 314.25(A), which requires metal covers and plates be grounded per 250.110. Unlikely to be energized does not relinquish the requirement. Besides, the only metal cover on a box that is unlikely to be energized is one that is not part of a complete system.

We used some metal "in use" covers on a job recently. Box grounded, obviously, device grounded, no problem. The metal cover attached to the device is "kind of grounded" thru the 6/32 screw heads only. Here is where it got wierd--a piece of 14 gauge green wire runs from the hinged cover of the plate to a connector you were supposed to put the 6/32 screw thru.

Egc needs to be pulled and connected to switch egc terminal: egc connects to ground screw on switch yoke, metal switch plate is screwed to metal switch yoke and is now bonded (grounded). See 404.9(B) Provisions for General use snap switchesIf the ground doesnt go anywhere after the box then all you've accomplished is now the ground pin on the plug is now a hot as well. So now you can get a shock from the box, outlet, and the case (if its metal) of whatever you plug into the outlet. I just noticed a mild shock while touching the metal light switch box in the garage. The switch is probably 20 yrs. old or so. Should I suspect a defective switch? I took a look at the metal box under our meter where the main breaker to the house. The ground rod protrudes above the ground, maybe 8" or so. The connection is very corroded.You don't know, and cannot know, whether the box is bonded to the electrical box until you test it. To test if the box is bonded, get a multimeter and do a circuit test using the hot wire and the metal junction box to see if a circuit is created. If the metal junction box is indeed bonded, then you can use the metal junction box as a ground.
Where the box is mounted on the surface, direct metal-to-metal contact between the device yoke and the box shall be permitted to ground the receptacle to the box. This provision shall not apply to cover-mounted receptacles unless the box and cover combination are listed as providing satisfactory ground continuity between the box and the receptacle.
grounding wire for metal box
A metal electrical box must have a separate grounding pigtail connected to it, then connected to all the ground wires in that box. Looping the feed wire ground around the grounding screw and using the end for a pigtail connection has been disallowed, beginning with the 2020 National Electrical Code (NFPA 70) article 250.148(C). Grounding a metal electrical box helps to protect people from electrical shock by providing a path for electricity to flow to the ground in the event of a fault. It also helps to protect the electrical system from damage by preventing the build-up of static electricity.
