I want to lay subfloor in my attic and wonder what to do with the exposed wiring that will be in storage areas. Details: We have an attic that we use for storage. We have a hip roof, and there is an area in the center with good headroom and a floor, surrounded on all sides by low headroom areas with no floor and exposed cellulose insulation NM cable may be exposed in attic. This is very common in modern dwellings. Armored cable / MC is not necessary in your case The area with the moisture stains is the attic opening. Technically yes. There should be several feet of distance from the opening to the romex. For me this is a minor maintenance issue for an electrican to relocate the circuit cable to the proper distance (unless new construction then it would be a major because of the current code violation) I noticed this exposed wiring coming up from the service panel and going across the exposed joists in the garage before entering the attic through the firewall into the house. I have called this out and recommended conduit as well as properly fire sealing the penetration in the firewall Wiring For Exposed Locations One approved way to run wiring across exposed surfaces is to mount an approved rigid conduit across the framing members or wall, then run individual THNN conductor wires inside the conduit. Such wiring is well protected against physical damage. The citation from the National Electrical Code is as follows
All wiring to be protected within 6 feet of attic access. Just wondering if this is IRC or NEC code? Electrician ran the 240 volt romex wire (feeding HVAC) next to the attic acces laying over the joists.

Placing a fold of electrical tape over the end of a unused wire is fine in a temporary situation, but not as a long term solution. It is best to screw a insulated wire connector over the end of the wires and cover the box with a blank plate as you have mentioned Still, depending on the installation's location (Arizona vs. Maine, for example), on whether or not the attic is vented or unvented, and on whether some of the junction boxes also contain light fixtures (which generate heat), installing insulation around existing wiring could violate one of these NEC performance standards
I have a service panel installed on the wall of an enclosed mud porch. The wiring to the attic runs (exposed) up to an access hole that then goes through the stud and into the attic where it then bran read mor If you are using a non-contact tester, then a false positive is common. Get a test light like this, and check each wire. There should be power when connecting to the black and white, or the black and ground and no power when connecting to the white and ground. Posting a picture of your situation would be very helpful Any exposed copper wire may cause an electrical short or fire. Add the Blank Wall Plate to the Box Attach a blank wall plate to the electrical box, using the provided screws. Some blank wall plates can be painted over
This is a more difficult and time-consuming wiring method but is more efficient in commercial applications where wiring runs must be exposed and thus must be inside some form of conduit. If the conduit used is PVC, the benefits are the same as NM cable, low Magnetic Fields (MF) but no Electric Field (EF) shielding It's often easier than fishing wire horizontally through finished interior walls.

outlet in the other. If an exposed conductor of a low-voltage wire comes in contact with 120v, the higher voltage can damage what-ever is at the end of the low-voltage wire.

Alternative: Wiring Without a Drill. Whether you do or don't have a drill at hand, this method enables you to run the cables without boring the ceiling or wall. It involves running the cables from the attic to the soffit through the gable vent NMB wire is rated for 90*C, but you're only allowed to use it as 60*C rated wire.
