What am I missing?Â* Are they actually talking about the casing?Â* The
casing is not 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.Â* MC for metal clad, and NM for non-metallic.



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


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 remember
the name of that street) Their house was where I learned about knob-and-tube
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 noticed
the name "Narragansett Wire Company" printed on the sheathing!

That was a very spooky feeling!
