Non-Metalic Wire?

I believe the Non-Metallic (NM) means the sheathing is made of plastic, not metal. There are times when it's required to have metal-sheathed wire and times when you can use Romex, non-metallic sheathed wire.

So that's the designation. MC for metal clad, and NM for non-metallic.

The product category is under

" non metallic jacket wire "

shortened to " non metallic wire "

in the product page - just to confuse people ..

NM is the typical NEC abbreviation for Romex(brand)-style cabling.

See here:

Understood but it specifically says non metallic "wire". And I do not ever recall Romex ever being called metallic or non metallic.

Probably another situation where those persons naming parts or describing something have no idea what the meaning of words are.

Functionality, never needed to replace the word function. And for that matter, "almost any word that has had "ality" added in the last 10~12 years.

Utilize, never needed to replace the word use.

And while I am on the soap box, When did the word button start being pronounced but-in. Garden, now pronounced gar-din.

Classic example of school no longer teaching students how to read the dictionary.

All future left voters.

Yeah, another example would be 2x4.

It's not uncommon, assuming that you accept that by referring to something by using the initials NM, it is being referred to as non-metallic.

"Romex® is the specific brand name for a non-metallic (NM) building wi re made by Southwire. In other words, Romex® is technically just one bran d of NM cable. However, the term Romex is often used generically (though inaccurately) to describe any type of NM cable, no matter which manufacture r made it."

Under description " Copper conductors are annealed (soft) copper "

Interesting story (at least to me) about NM wire.

I'm sure that most of us are familiar with the "cloth covered" NM wiring in older homes. You know, same concept as Romex, except that all the sheathing is cloth, not plastic. Well...

My godparents lived on Narragansett Blvd in Chicopee MA. (be sure to rememb er the name of that street) Their house was where I learned about knob-and-tub e wiring as a teenager. I helped my godfather pull some new wires through the K&T fixtures. It was my first experience with house wiring. Fast forward a decade or so when I was about to buy my first house, a house located in western NY. While visiting my godparents they handed me a wad of cash to help with the down-payment.

So, I move in and I'm getting ready to do some wiring work on my own house. A house that some nice folks that lived on Narragansett Blvd helped me buy. Narragansett Blvd, where I had my very first experience with house wiring.

Imagine my surprise when I looked at the cloth covered NM wiring and notice d the name "Narragansett Wire Company" printed on the sheathing!

That was a very spooky feeling!

.. if you say so < ? > John T.

Yes it is still a copper conductor, it is the sheathing compared to armored cable which the description is also confuusing because it say aluminum and the conductors are copper.

Another word peeve with = wid?

Classic example of geographical variation, y'all.

In my carpenter apprentice classes, it's neither 2 nor 4 but 38 x 89. Shocked me to learn that the blade of my skill saw is 89mm from the edge of the sole plate: it's been aqn inch and a half since Pontius was a pilot.

Apparently they are talking about the casing. Down at the bottom of the p age they say Copper conductors are annealed (soft) copper. Poorly written ad.

Can anyone here name a non-metallic material that a good conductor of ele ctricity? Who educates these people?

It is non metallic sheathed cable by definiution - has copper conductors. What do you expect af a big box store's description of technical products???

I thought it was the inbread homeschooled backwoods southern repugnicans who couldn't read or write past a 3rd grade level. Those and the sons of rich new york mobsters that run for president as a way to "improve their brand"

In other word - current "right" voters (or at least TRUMP voters) and Trump offspring

"Romex" is not wire - it is CABLE. A "wire" is a single conductor
