THHNThe types of wire most commonly installed inside of conduit are THHN and THWN. THHN/THWN wires are individual, insulated, and color-coded wires.
What is the difference between NM and NM-b wire?
Closely related cable types are Type NMC, which has a corrosion-resistant outer covering, and Type NMS, which contains, in addition to the usual power conductors, communications (signaling) wires. When the letter B is appended, as in NM-B cable, it indicates that the conductor insulation is rated for 90 degrees C.

Can you use NM without conduit?
The bottom line is this: if you could use NM there without conduit, then you could sleeve it in conduit. If you can't use NM there without conduit due to weather exposure, then adding conduit doesn't get you anything. The inside of a conduit in a wet location is a wet location.
Can you use THHN instead of Romex?
Depends on your local ordinances. I personally wouldn't. If using all conduit outside, pull THHN/THWN instead of Romex.

If you want to call the interior a "location", that's fine; just call it a "wet location".
Can NM be run in complete raceways?
NM can be run in complete raceways just like single conductors. The fill has to comply with Chapter 9, Note #9.
Can NM be used in conduit outside?
What you might be thinking of is NM isn't allowed in conduit outside. That's because the inside of conduit installed outdoors is considered a wet location and NM isn't allowed in a wet location. This just changed a few cycles ago. J.
Do you need to use single conductors in a raceway?
There is even a requirement that it be in a raceway where installed in a building that is required to be of Type I or II construction. 334.10 (5). Not sure why anyone would want to do that...if you have to install the raceway, you might as well use single conductors in the raceway.
Can you size conduit as if it was a round conductor?
It's not prohibited, but you are supposed to size the conduit as if it was a round conductor the same size as the larger dimension.
Do you need to fill a raceway sleeve?
There is no fill requirements when using raceway as a protective sleeve though.
Can a single insulated conductor be considered a cable?
Assemblies of single insulated conductors without an overall covering shall not be considered. a cable when determining conduit or tubing fill area. The conduit or tubing fill for the assemblies shall be. calculated based upon the individual conductors.
Can you bury non-electrical tubing?
In fact, you can bury non-electrical tubing like plumbing PVC and then run UF cable in it, as the tubing is only a sleeve, not a raceway.
Can you run UF cable in raceways?
Off the top of my head without looking it up:#N#NM-B cable is not permitted in any wet location including aboveground and underground raceways.#N#UF-B cable is permitted in any outdoor raceways, minding conduit fill of course. In fact, you can bury non-electrical tubing like plumbing PVC and then run UF cable in it, as the tubing is only a sleeve, not a raceway.
How many AWG wires can you put in a conduit?
Better to use many conduits, limiting each to four 14-12 AWG circuits or three 10AWG circuits.
How many conduits to run 12/2?
The best way to avoid that derating is numerous conduits, so you are not exceeding the nine practical limit for #12 and #14, and the six practical limit for #10. For instance, five conduits will barely get you by: Two conduits for the four 10/3 and two 12/3 - and three more for the twelve 12/2. You will be full-up at that point, and would need to run more conduit to add anything. I would consider 8 conduits. Since you're already doing six, doing two more is no trouble. You're already there, have all the right tools and supplies, and by #5 you're getting pretty good at it.
How many AWG wires are needed for 20A?
For instance if you aim to run 20A, and use THWN-2 or USE-2, 10 AWG wire is 40A x 45% = 18A -- not enough, you must go to 8 AWG wire.
How many conductors are in a 12/2 box?
In one box, you propose twelve 12/2 cables in a single conduit. That is 24 conductors (grounds don't count). Because you have so many, NEC rule 310.15 (B)3 requires you de-rate the conductors at 45% (per table 310.15B3A)
Why open a second bay in sheetrock?
I would consider opening a second unused bay in the Sheetrock wall up to the atti so that you can run additional cables easily.
Is conduit large enough for NM-B?
I believe the conduit is appropriately large enough for the number of conductors, but I've seen other answers regarding running NM-B through conduit where conduit length is a concern.
Do conduits have to be separated?
Keep in mind conduits must have a certain spacing in order to count as separate conduits. That is for air circulation, as the name of the game is to cool the wires and conduit.

What is NM sheathing?
The sheathing on NM cable does offer some protection against incidental physical damage. Sheathing on Romex is made of tough polyvinyl chloride (PVC) thermoplastic. The sheathing on both 14 and 12 AWG wire is 15 mils thick. Still, no matter how strong the NM sheathing, it is not mean to exposed applications. Typical locations include: 1 Inside wall cavities covered with finished wall surfaces, where the cable will not be accessible. 2 Inside the air voids of masonry block or tile walls but only where dry: the walls cannot be damp or wet. 3 Between exposed joists or studs, provided the cables are recessed away from the face of the framing members. This is normally done by boring holes in the centers of the framing members and running the cables through the holes.
