can i use greenies on non metalic electrical box Certain medical imaging rooms do not allow ferrous materials and so we wanted to install PVC boxes with PVC conduit going to them. 314.3 seems to allow nonmetallic boxes as . Oil canning is defined as the perceived waviness of a metal panel and is an inherent characteristic of light-gauge, cold-rolled flat metal products. In other words, it’s a visual phenomenon that makes metal panels look wavy or somewhat distorted, especially in the broad, flat areas of a metal roof or wall system.

It could be Dormers, Gable End Vents, Ridge Vents, Turtle vents or Turbines Vents. These all work well and are typically installed near the top or the peak of the roof, called the ridge. To get the best performance, these vents should be within three feet from the ridge.
If you have a massive box with a zillion ground wires you could make an even longer bare pigtail, and thread multiple greenies on it. Most of what you can do with greenies, you can do with crimp rings. Crimp rings are cheaper and take up less space, but greenies are much easier to undo . Even if the device does not complete the ground, Romex or NM wiring can always be used with metal electrical boxes by attaching the bare or green grounding wire to the box .
Certain medical imaging rooms do not allow ferrous materials and so we wanted to install PVC boxes with PVC conduit going to them. 314.3 seems to allow nonmetallic boxes as . My inspector wants me to use "greenies" to connect the ground wires. Why are greenies (green wirenut with a hole in the top for the pigtail) favored over a standard wirenut? . As long as we adhere to 110-12 (the catch all code!) then barrels are just fine. Put them strategically into a corner, and strategically fold all conductors into the box, crossing .
When tying the grounds together in an electrical box, I have been told (per local code) that I must mechanically connect the grounds (versus just twisting them together). . There's only one product that is supposed to be code approved that can be buried. You are correct, a junction box must be used and must be accessible and covered.
The NEC permits use of plastic boxes with non-metallic cable only. This includes Romex or NM wiring. You should not use metal-sheathed or "BX" wiring with plastic electrical boxes.
Does your "BX" cable have a separate green insulated ground wire or a smaller bonding wire in contact with the metal jacket? My electrical answers are based on 2017 NEC, . Plastic new work boxes are commonly used with non-metallic cable wiring. They offer quick installation and are good for most residential applications. Metal new work boxes .If you have a massive box with a zillion ground wires you could make an even longer bare pigtail, and thread multiple greenies on it. Most of what you can do with greenies, you can do with crimp rings. Crimp rings are cheaper and take up less space, but .
Even if the device does not complete the ground, Romex or NM wiring can always be used with metal electrical boxes by attaching the bare or green grounding wire to the box with a screw. Many metal electrical boxes can be ganged, while most plastic boxes cannot.
Certain medical imaging rooms do not allow ferrous materials and so we wanted to install PVC boxes with PVC conduit going to them. 314.3 seems to allow nonmetallic boxes as long as nonmetallic raceways are used. Is the installation allowed if we use PVC conduit? An electrical inspector questioned whether this would work due to grounding concerns. My inspector wants me to use "greenies" to connect the ground wires. Why are greenies (green wirenut with a hole in the top for the pigtail) favored over a standard wirenut? Also, he wants to see these installed at rough-in, but doesn't seem to care about any other pigtails that might be required. As long as we adhere to 110-12 (the catch all code!) then barrels are just fine. Put them strategically into a corner, and strategically fold all conductors into the box, crossing them as little as possible. Doesn't take anymore time than cramming them in . LFMC (Sealtite) connectors are metallic and if you needed to bond the LFMC you would use a grounding or bonding bushing within the enclosure on all connectors and bond all together. However, this is low voltage.
The first exception permits the use of nonmetallic boxes with metal raceways or metal-armored cables provided that there is an internal bonding means installed to ensure electrical continuity between all metal cable sheaths and metal raceways.
When tying the grounds together in an electrical box, I have been told (per local code) that I must mechanically connect the grounds (versus just twisting them together). Sounds good. I can use wire nuts or “Buchanan caps (copper crimp connectors)”, which require a crimp. There's only one product that is supposed to be code approved that can be buried.
