Answer :
Yes, unless it is located in an inaccessible location. We can only run NM over the joists if it falls within the 2′ region measured from the top of the ceiling joist to the bottom of the roof rafter, and we must secure it every 4′. For example, we cannot run NM behind an air handler.
Is it possible to run wire on top of ceiling joists while taking this into consideration?
a cable that is run across the tops of the joists Because any cable that runs across the top of joists must be secured if the attic is accessible by permanent stairs or a ladder, any cable running across the top of the joists must be protected. Protecting the cable is as simple as adding “substantial guard strips,” which can be as basic as a 1×2 furring strip on either side of the wire to provide adequate protection for the line.
Is it possible to run electrical wiring through the attic?
An attic can be a potentially dangerous place to work. Lighting, cable, computer networking, and sound systems are all examples of systems that may necessitate the installation of wiring that must pass through the ceiling. If you live in a single-story home or the upper floor of a multi-story home, this implies that you will have to enter your attic to run wiring.
As a result, is it possible to run Romex under joists?
Regarding the romex that runs beneath the joist It plainly allows the use of romex in crawl spaces, just as it enables the use of romex in a standard basement. As long as the crawl space does not contain any standing water, it is absolutely lawful to be in it. (I’ve also been in a lot of DRY crawl areas as well.)
What is the best method for fishing wire through ceiling joists?
Wrap electrical or duct tape across the wires where they double back to prevent them from tangling. This will help to prevent the fish tape and wire from coming apart. Then we’ll get back to the ceiling light fixture hole. Pulling the fish tape will pull the electrical wire along with it as it snakes through the wall and ceiling, so be sure to reel it in and wind it tightly.

Is it possible to pass electrical cable through a header?
Wall headers are the horizontal strips of wood that run along the top of window and door openings in your home. When installing wiring in your home, it is always ideal to avoid drilling through structural features such as walls or floors. If there is no other option, wires can be tucked into notches in your header to maintain as much structural integrity as possible while saving money.
Is it possible to pass two wires through the same hole?
When drawing numerous wires through a single hole, extreme caution should be exercised to avoid causing a friction burn on the other wires within the hole. Whatever the case, you should only feed one wire through a single hole, regardless of whether it is Code. Even if your wires are running parallel to each other, drill a separate set of 3/4″ holes for each wire you want to run.
Is it possible to run electrical wires above ground?
Runs of buried wiring that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches (whichever is less) to the point where the wiring terminates above ground, which must be at least 8 feet above ground level.
Is it possible to put insulation over electrical lines in the attic?
Insulate the joists between the rafters if your attic does not already have insulation in place. It is not necessary to compress the insulation in order to fit it under pipes or cables. Instead, cut to the centre of the batt’s thickness, so that you have a flap under the wire and one over the wire to finish the job.
Is it possible for ceiling joists to go perpendicular to rafters?
Risers and rafters exert an outward force on the outer walls, which is countered by rafter ties. It is possible that when ceiling joists are put perpendicular to the rafters, inspectors will discover rafter tie framing members every 4 feet running above the ceiling joists and joining opposing rafters.
Using the same hole, can you run plumbing and electricity at the same time?
Plumbing and electrical work in the same wall cavity are acceptable, even if they come into contact with one another. Keep in mind that every electrical wiring is shielded. Ground wires that are not shielded are also acceptable.
How often should Romex be stapled together?
334.30 Securing and Providing Support Cables with nonmetallic sheathing must be supported and secured with staples, cable ties, straps, hangers, or similar?ttings that are designed and installed so as not to damage the cable at intervals not exceeding 1.4 metres (4 12 feet) and within 300 millimetres (12 inches) of every outlet box, unless the cable is protected by a metallic sheath.
Is it possible to surface mount Romex?
Exposed romex NM cable is permissible to be run on the surface of the building finish, as long as it is not exposed to the elements. If it is subjected to physical harm, it is necessary to provide additional protection. Considering that the term “susceptible to bodily damage” is not defined by the NEC, it becomes a question of interpretation.
Is it necessary to staple the Romex?
It is required by code to staple them together during new construction. However, if you’re fishing wires through an existing finished wall as part of a remodelling project, it’s acceptable to leave them loose. It goes without saying that they should be secured to the box in both circumstances as well.
How many Romex wires can be stapled together before they become unusable?
On older homes with joists that are as hard as iron, I use little romex staples to secure one cable. Our rule of thumb was usually one wire per staple and a maximum of two wires per staple when two wires were placed side by side. If you need to connect more than two wires, you can utilise a technique known as stack it’s.
Is it possible to expose Romex in a crawl space?
As long as the nm cable is not exposed to the elements, you can run it there without issue. If it starts to rise in the cabinets, It needs to be protected, and Flex is suitable for this. You’ll still need to keep an eye on it! When running the NM via the crawl space, it is permissible as long as the NM is routed along the side of the structure, through bored holes, or on running boards.
