Can I run NM wire through this type of flex legally


According to the 2015-16 UL White Book, this product is only allowed to contain the following:

Optical fiber cables (Types: OFNP,OFNR,OFN,OFNG,OFCP,OFCR,OFCR,OFC,OFCG). Communications cable (Types: CMP,CMR,CM,CMG,Cross-connect wire). Power-limited fire-alarm cable (Types: FPLP,FPLR,FPL). Community antenna television cable (Types: CATVP, CATVR,CATV). Low-power network-powered broadband communications cable (Types: BLP,BLR,BL).

Which means no NM cable, no lamp cords, no extension cords, nothing but the types of cable listed in the table above.

First, does the window open, and is it required by fire codes for emergency egress?

If so, you could remove the window and install a shorter or narrower window, that still meets code, and then use the margin to pass through your utilities. I would use fairly tough metal conduit for electrical to make it resistant to damage.

I already see a wood margin that might suffice.

Otherwise you'd want to permanently remove the window from service as a window, by doing a surface treatment on both sides that renders it not a window. Either remove the window entirely or panel it over on both sides so it is entirely buried, remove a pane, put the service through, and fill the voids with insulation.

I hate to remove a classic window like that made of solid material and well installed, so I would go for the remove-a-pane...

Posted By: rukkus11 I beleive you have your main hot wires coming in your switch box and from there you have wires ran to you light which the switch controls. You can leave that there and tap off your main wires before the switch in your switch box and your new receptable in your closet will be hot all the time. You won't have to turn the switch on while using the new receptable. So you would have your light switch for your light and a new receptable in your other closet that's hot all the time. Is this the way you want this done?

Jim, I really have no use for the light. I can cancel it alltoghether. (you posted above while I was typing below)


A) I prefered switched since I would like to turn off the wireless router when I do not use it for security purposes. In my current setup my router is running through remote on/off switch. If it is a problem to keep it switched, I can get rid of it.

B) The bulb lights up when I flick the...

"Romex" is a brand name. The 12-2 NM-B specification is more important than the brand name. (12-2 will support up to 20 amps for typical runs).

I used the term Romex as that's how most folks refer to it, even though it may be made by other manufacturers. Just like tissues are often called "Kleenex", even though many other companies make them.

That sounds OK to me. Based on the correction "Bud" supplied, you could run a single NM-B cable in the large conduit now. If you ever need to run additional lines, you could pull that cable, install junction boxes top and bottom, and run individual wires in the conduit. Or, go ahead and transition now to save future work.

Better yet, dedicate the 1-1/2 inch line to data needs, and install additional 3/4" conduit runs for future power runs. I would cap any unused lines to keep out insects and drafts.

Oh, and just for clarification, make sure you use grey colored PVC "conduit" and not white PVC water pipe....

Thank you for your reply!

I want to clarify that the product is not "UF cable". Here is the Home Depot detail: 1/2 in. Ultratite Liquidtight Flexible Non-Metallic PVC Conduit. Ultratite NM Flexible Conduit is used where conditions of installation, operation, or maintenance require flexibility and/or protection from liquids, vapors, solids, or weather. Applications for use include:


circuits, motor feeders, branch, and control circuits. This product is used for commercial and industrial locations.Can be used for exposed or concealed locations.Direct burial and encased in concrete. Crush resistant. Dry locations. Smooth metal interior for easy



I just noticed one of the questions posted on Home Depot asked about rodents and answer stated not rodent proof so I realize that I cannot lay it on the ground. I will need to tack it to the underside of the deck.

Regarding the ground wire thanks for the help. Interestingly the previous job was...

Wiring methods have changed over the years from knob and tube to flexible armored cable (Greenfield) to nonmetallic cable (NM), conduit (EMT), and underground feeder (UF) cable. From about 1890 to the present, wiring methods have become much safer due to the installation types of wiring and the addition of ground wires. Between 1890 and 1910, knob and tube wire was all the rage in home building. Individually insulated wires were held in place by porcelain insulating brackets.

They also passed through wood in porcelain tubes that protected the rubberized cloth fabric from damage. This practice had a hot wire and a neutral wire that were run separately for safety and so they could be spliced together. To do this, the insulation was stripped back, a wire was wrapped around the exposed bare wire, and the splice was soldered together before being taped to cover the splice. The downfall was the wire was exposed to everything and there was no ground wire utilized.

In the...

This can also be caused by an attempt to write more than one protobuf message to a single stream. The solution is to use SerializeWithLengthPrefix and DeserializeWithLengthPrefix.

Why this happens:

The protobuf specification supports a fairly small number of wire-types (the binary storage formats) and data-types (the .NET etc data-types). Additionally, this is not 1:1, nor is is 1:many or many:1 - a single wire-type can be used for multiple data-types, and a single data-type can be encoded via any of multiple wire-types. As a consequence, you cannot fully understand a protobuf fragment unless you already know the scema, so you know how to interpret each value. When you are, say, reading an Int32 data-type, the supported wire-types might be "varint", "fixed32" and "fixed64", where-as when reading a String data-type, the only supported wire-type is "string".

If there is no compatible map between the data-type and wire-type, then the data cannot be read, and this...

Flexicution is the combination of words “Flex” and “Execution”. It was created by Logic, who explained it on Twitter as: “a term and funny made up word for killing SHIT.”

The song is a braggadocious rap track filled with references to the recent success of Logic’s sophomore album, The Incredible True Story.

The outro is a duet between Logic and his wife, Jess Andrea, with John Lindahl contributing the male falsetto vocals.

Anticipation for the song began on April 5th 2016 when GFuel released an interview containing a teaser of his unreleased song, “Flexicution.” Since that day, fans have been demanding Logic #DropFlexicution. He went onto play the same snippets at various shows on his Incredible World Tour and teasing other snippets on his snapchat (Logic301) before finally dropping the track on June 13th 2016. He broke down the track’s creation during a Power 106 interview.

Logic also spoke about “Flexicution” in an interview with HardKnockTV.

The electrical system in most homes and businesses is wired using sheathed, insulated wire. Romex® is a brand name that is well-known for manufacturing this type of electrical wire. Romex NM cable, (pronounced rome-ecks), and competing brands of cable contain two or more insulated conductors (wires) in a flexible plastic sheath that can be run through walls, under floors, through attics and so on. All brands of flexible, sheathed cable which can be used interchangeably, though many electricians prefer to use the brand name product. The labeling for all electrical cable is standardized and so is the same regardless of who manufactures it.

Flexible sheathed cable is easier to run through holes in studs than metallic sheathed cable, it is also cheaper. Romex cable is labeled as NM-B, which means the sheathing is non-metallic cable; other brands use code "NMC". The "NM" designation is used to distinguish it from metallic sheathed (BX or AC) cable. Another designation, UF,...

Very helpful tips Aaron. I did double check and the THHN 8 guage alllows up to 55 amps, so I went with that, and a size smaller ground at 10 ga. The big box store associate was actually very helpful, and recommended less expensive 1" gray PVC conduit for outdoor use, and glue for joints. I only need one 90 degree curve coming out of main panel, with a straight shot 20 feet to entry point, with 4 foot hanging braces.

Yeah 1" is good, 3/4" is minimum for four #8s. It might be helpful to use a synthetic dielectric grease to lube wires for easier pulling through the conduit. You want the conduit completely installed before you pull wires through, with the necessary access points (junctions) as needed. Also, when you pull the four wires through, I recommend that you also pull an additional piece of string (as long as your wires) so that it can be used to pull another wire in the future. You never know and string is cheap. Either you'll thank yourself or someone will thank you...

It is against (Electrical building) code, so yes, it is considered dangerous.

The National Electrical Code® NEC® states:

NEC ARTICLE 400 Flexible Cords and Cables General 400.1 Scope. This article covers general requirements, applications, and construction specifications for flexible cords and flexible cables.

400.8 Uses Not Permitted (ref. Extension Cord) Flexible cords and cables shall not be used for the following: (1) As a substitute for the fixed wiring of a structure (2) Where run through holes in walls, structural ceilings, suspended ceilings, dropped ceilings, or floors (3) Where run through doorways, windows, or similar openings (4) Where attached to building surfaces (5) Where concealed by walls, floors, or ceilings or located above suspended or dropped ceilings

All A/C power run through or concealed within the walls or ceilings requires use of proper code compliant in-wall rated building electrical wire, manufactured and listed by UL or CSA...

When they wired my new home for phone lines, they used eight conductor CAT5e cable, all brought back to a central junction box. Since I just use a cell phone, I converted the wall connectors to a Ethernet configuration for my LAN. They can be converted back to a phone configuration if necessary in the future. I also added a Ethernet switch for distribution to the junction box and fed one line back to the box from my router.

I suppose you could use the other four unused Ethernet wires in the cable (Or usually just two are needed) to run phone signals on the same CAT5 concurrently, though that could cause interference to either system. Phone wires carry just a few volts except for the ringing signal, which can be up to 90V during ringing, but all low current. I found out about the 90V once when I was holding the wires and someone rang my phone number.

In a pinch and not recommended as they aren't usually twisted pairs, you could use a regular phone line for a Ethernet line on...

With Real Romex®, Pulling is Believing

The History of Romex®
The Romex® brand of Non-Metallic Building Wire (“NM”) originated in 1922 with its development by the former Rome Wire Company, a predecessor to General Cable Corporation. On September 5, 2001, Southwire purchased the electrical building wire assets of General Cable Corporation. One of the most valuable assets purchased by Southwire in that acquisition was the Romex brand of Type NM cable. The Romex brand of Type NM cable has now been promoted and sold by Southwire and its predecessors for 88 years and Southwire considers its Romex trademark to be one of its most valuable brand names. Romex is a federally registered trademark and we vigorously monitor and protect the use of the Romex brand in North America and around the world. Don’t just look for generic NM cable, look for Southwire’s Romex® brand Type NM cable!

Southwire continues to apply SIM Technology® to commercial and industrial building wire and...

One of the best reasons for mounting your new flat panel TV on the wall is the sleek and stylish look that it gives the entire room. Just look at how it complements our fireplace. What’s not so sleek and stylish, however, are all the cords and cables dangling from below the TV, running across the mantle and down the wall. What an eyesore. To hide them, we’re going to run these wires through the wall and up to a point behind the TV where they will be out of sight, hidden from our view.

Today, in this first of a two-part series on wiring a wall-mounted flat panel TV, we’re going to tie into an existing electrical outlet and run new electrical wire and TV cables up through the wall. Then we’ll make a 90-degree turn and route the wiring through several studs before we reach our destination behind the TV. In the next video, we’ll install an electrical box and receptacles and connect the wires and cables. Now before we begin, if you have any hesitation about working with...

Not legally per NEC, the code is real unfriendly toward this, the code makes you treat the NM cable like one big fat round cable, then only allows 53% for one cable or for two cables you are only allowed 31% fill.

Chapter 9 note 9, the major dimension of elliptical shall be used as a circle for calculation of conduit fill, Encore wire states that dimension of 12/2 is .4, pi r squared area of .4 is .63, 10/3 measures .43, equaling area of .58, so each of those cables would need 1 1/4" flex by themselves for 53% fill, or for both cables total of 1.21" you would need 2 1/2" flex. It just doesn't work to code.

And check NEC 240.4(D) Protection of small conductors, #10 must be protected at no more than 30 amps and #12 at 20 amps.

Put a box at both ends and pull THNN conductors, 3 #8's, 2 #10, +#10 ground will fit in one 3/4"...

Sorry it is "Other Space Used for Environmental Air". It does not have to be either a duct or a plenum.

The code states that a duct or a plenum is "specifically fabricated to transport environmental air"

A stud or joist cavity is not fabricated to transport environmental air, it is something that is "altered to be able to transport environmental air.

If it is either a duct or a plenum, then there would be no need for Section 300.22(C) because what it covers wouldn't exist.

Section 300.22(C) exception specifically addresses this type of situation

Exception: This section shall not apply to the joist or stud spaces of dwelling units where the wiring passes through such spaces perpendicular to the long dimension of such spaces.
It says that Section 300.22 does not apply to this situation. The section is titled "Wiring in Ducts, Plenums, and Other Air-Handling Spaces".

The exception says this section does not apply to this...

I have a dumb question regarding putting UF and NM inside a raceway.

Last week one of our well diggers was having a tough time with his trench caving in on him, so he was trying to be a nice guy and assembled the RNC as he was back-hoeing in the water lines. The problem that came up was that he put UF inside it and he did not use expansion joints below the RB panel or the well-head, never mind that he is not a licensed electrician.
I will find out this week, but the boss was saying that we have to remove the UF and install THHN.

Where is it stated that UF can't be inside a raceway the entire length of the wire, which in this case was 40'?

Along the same lines, when I am wiring up a garage in NM and the customer wants an outlet on the exposed side of a pillar, for example 3' down, I put the NM inside EMT with either a EMT-Romex connector at the top or a white plastic insulator. At what point do I have to derate the NM? 334 says that it can be placed...

Q. Can someone tell me if the National Electrical Code (NEC) limits running flexible metal conduit to any particular length? I ask this because I understand Greenfield for a light fixture shall not be longer than 6 ft. I would like to know if I can extend a 7-ft run of flexible metal conduit to a motor. —J.C.

A. The NEC does restrict the length of flexible metal conduit for lighting fixtures to 6 ft to limit the ground return path. Sec. 430-135(b) restricts the length of the motor leads between the motor and required junction box to a maximum of 6 ft, regardless of what type of conduit they are contained in—this pertains to the motor leads only. The length of flexible metal conduit for other uses isn’t restricted, while a grounding conductor is included with the circuit conductors. In response, the author may run any length of flexible conduit from the disconnect to the motor junction box, provided he also meets the requirements for support of the flexible conduit and...
