That’s definitely a violation – sheathing needs to go all the way into the box.
Can you use a plastic box as a junction box?
Plastic electrical boxes, sometimes called junction boxes, have plenty of pluses, including low cost, convenience, and ease of installation. But they’re not the best choice for every application. When plastic doesn’t make sense, the standard alternative is a metal box.
Can you splice in a junction box?
When splicing wires, always use a junction box to place all the spliced wires. Junction boxes protect from electrocution and fires by containing any sparks that occur during a short circuit. Attach the junction box to a wall stud or ceiling joist in a spot that won’t place undue stress on the wiring.
How do you cut plastic electrical box?
One of the easiest and most precise ways to make the cuts is with a rotary cutting tool, often referred to as a Dremel tool. When cutting with a rotary cutting wheel, place the cutting tool in the centerline then move it back and forward to finish the cut. Always use caution when using sharp tools such as these.
Does a junction box need to be metal or plastic?
In many cases, your choice of a metal or plastic electrical box is one of personal preference, economy, and ease. In a few cases, though, the choice is clear-cut and obvious, mainly with respect to grounding. Most do-it-yourselfers prefer plastic electrical boxes, while electricians use both metal and plastic boxes.
Does a junction box have to be metal?
A plastic electrical box might be a better choice for your application if: You’re using non-metallic sheathed wire (often called Romex wire). Romex wire and plastic junction boxes are frequently used together, but metal enclosures may be acceptable as well (depending on the project).
Do plastic junction boxes need clamps?
Single plastic boxes do not require internal cable clamps, but the cable must be stapled within 8 in. of the box. Larger plastic boxes are required to have built-in cable clamps and the cable must be stapled within 12 in. of the box.
Can you splice inside electrical panel?
Wire splices can be done inside a panel, and often are necessary to repair a double-tap at a breaker (two wires under one breaker connection) using a short wire called a “pigtail,” extend wires that are a little too short when a panel is replaced, or as part of moving circuits from a main panel to a subpanel for a
Do all wire splices have to be in junction box?
Electrical splices can never be left on their own in a wall or ceiling cavity. Instead, all splices must be contained within an approved junction box or fixture electrical box.
Are in wall splices legal?
The only condition is the splice has to be fished, meaning you cannot legally use this splicing device where there is no drywall yet installed because the NEC expects you in this case to use a proper junction/outlet box, so the splice can later be accessed.
How do I run Romex in a plastic box?

Do junction boxes have to be exposed?
Junction box covers must remain accessible; they cannot be covered with drywall or other surface material. A junction box is most often used where an electrical circuit branches off in two or more directions from a location where an outlet or fixture is not practical.
Can I replace metal electrical box with plastic?
Homeowners can replace their metal electrical box with plastic if non-metallic cables come in and out of the box. However, the downside of plastic electrical boxes is that they distort or crack under stress, and PVC can melt due to overheating.
Do I need to ground a plastic junction box?
Plastic electrical boxes have their pluses and minuses. Because they are plastic, there is no need to attach a ground wire to it. Since it is made of a non-conductive material, switches and outlets cannot short out if they touch the side of the box.
How do you wire a plastic junction box?
Quote from the video:
Quote from Youtube video: Code or nec dictates that no wiring splices are allowed outside of an improved enclosure pvc junction boxes are one type of approved enclosure used to protect wire and cable connections.
Why are there no plastic electrical boxes?
Though PVC can melt when overheated, it does not conduct electricity like metal does. Use plastic boxes when: There are non-metallic (NM) cables leading in or out of the box. Metal-sheathed wiring relies on bonding with the metal electric box for grounding and should not be used in plastic boxes.
Can junction boxes be behind drywall?
Per their requirements, electrical boxes must be covered with matching electrical box covers. You can’t cover them with drywall, paneling or other wall coverings. The box also needs to have enough space for the conductors inside.
Can you use a plastic junction box in a crawl space?
You Can Add a Junction Box to a Crawl Space

What is PVC junction box?
PVC Electrical Junction Boxes are surface mounted enclosures without entrance hubs which allows multiple conduits to be connected and wire splices made within. All junction boxes include cover and mounting screws and may or may not include mounting feet, depending on the size.
How do you open a junction box?

Can you hang a ceiling fan from a plastic box?
Conventional metal or plastic rough-in boxes aren’t supposed to hold any more than 50 pounds, and most fans exert more force than that. Consequently, to hang one you need a support system consisting of a metal box attached to blocking or metal rods that you can secure to the ceiling joists.
