NM (non-metallic) cable. There may be other brand names but that is basically what it is.

The stuff pictured looks like it's 60's or so era. I usually think of NM cable as anything plastic sheathed but I believe that the cloth-like wrapped stuff is still the same.

Very cool, thanks.

NM, or non-metallic cable, is the code defined term for it.

A brand name would be, for one example, RomexTM.

That is 'cloth-covered' NM with thermoplastic insulation on the conductors.

Prior to that was cloth covered with rubber insulation and tinned conductors (the copper was tinned to prevent chemical interaction between the copper and the rubber insulation).

When you seen rubber insulation it is almost assuredly bad in the walls and junction boxes and needs re-wiring.

Thanks Jerry. BTW, I like the ask code man site.

Now you've gone and done it. Jerry'll have to let his hat band out a size or two!
