There is no paper in Romex in first world countries.

It must be to reduce the friction between the sheath and the conductors. That way, when you pull the cable and it snags, the sheath may get nicked or just keep gliding past whatever imperfection snagged it, all without transferring the friction to the conductors in the cable.

As others have said, the paper is a filler, but the paper also prevents the jacket from bonding to the conductor insulation in the extruding process. Yes, the cable could be manufactured without the filler material, but would be more expensive to make and to install.

How much does a roll of paper romex cost? I want to compare it to our romex that does not have the paper.

Also, can you explain why it would be more expensive to install without the paper?

Just going to the HD site, they pay about the same as us when you adjust for currency.

I bought a pair of those strippers once that are supposed to score NMD and it stunk (maybe it was my complete lack of manual dexterity). I think theyíre designed for American Romex.

i accept your premise, but I reject the conclusion
By preventing the jacket from sticking to the conductors they achieve a greater flexibility of the whole assembly, plus lesser degree of snagging on rough edges.

For sure. Also easier to strip. You can grab the bare ground and just pull it even. It easily cuts through the sheath

A 250 foot roll of 12-2 at Home Depot costs $72.97, American. A 75 meter roll of 12-2 at Home Depot Canada costs $93.04, American. So you pay $20 more per roll and get 4 feet less.

Must be Canadian import charges in there. Just checked local big box (Lowes here...HD gave up on North Carolina East of 95) and it's $69.98 for a 250 foot roll. At HD in Knightdale (Raleigh), the closet HD to me at about 100 miles away (that's 160 km for Canookistanis), it's $70.47. Basically the same price.


Don't know about NM-B as I'm mostly industrial and the only NM-B I ever mess with is in my house but once in a while we get industrial cables that don't have the little layers of what looks like mylar that I was told are called separating tapes, or paper in them where the jacket adheres to the insulation, kind of like UF, and it's total crap. It's almost impossible to strip it apart without nicking the insulation. The price is usually almost the same with or without it.

Not worth the extra $20 a roll for the 'paperless' experience to me.

This pisses me off. Why 70m? Why not 76m which is 249' 4"? Why not 75m which is a nice round number and 246'? Canadians get shorted again.

The $20 is not because itís paperless, we pay more for many things here.

Look up a roll of single conductor cable and you will see we pay about $20 more for it too

Par for the course up here. Take just about any item, add the exchange rate, and it's still more up here.

Smaller market, higher delivery charges etc...

If I was up there I'd be paying $20 more than what I get down here.
