Hello, could someone tell me what kind of wire this is I’ve seen it in a few houses and I cant seem to find what kind of wire it is. looks like NM but it has a cover ground? On the insulation it says NM-B-2 but I cant find it online?
CCA wire or some other kind?

In the second picture there appears to be a white wire missing, if that’s the case it could be NM but from Canada. I believe they make a black red NM cable
If it is marked NM-B then it is NM-B... My last house had some NM cable like that. I think it was installed in the 60's and the ground was insulated green instead of bare. Not sure who makes it. I think is was old enough that the ground was also 1 size smaller than today (#16 ground in a 14-2 NM cable).

Is there a manufacturer name in the cover printing?
This a newer house, maybe built less than 3 years ago, I’ve seen different types one with a neutral and some without, also the wire size is a 8 AWG in a orange sleeve. I will try to take more pictures the next time I come across another one and post them here.

It looks like Copperweld NMB to me but I don't see where they offer it without a white wire.

Actually the spec sheet doesn't show conductor colors so I have a feeling 8/3 is Black/Red/White/Green and 8/2 is Black/Red/Green.

Same here, and I've seen it hour-glass shaped to fit between the wires, in place of filler paper.
I thought Copperweld was steel core copper wire used for antennas?It looks like Copperweld NMB to me but I don't see where they offer it without a white wire.

It is, as well as the center wire in RG-6.
Copperweld (a company name) can be copper-coated almost-anything.
Here, CCA means copper-coated aluminum.

With the CCA they're pushing the ampacity to color size so 12awg is white and 10 is yellow ect.
This is the reason why I was under the impression that it was CCA, I keep on seeing the wire i newer houses I just haven’t been able to have with legible markings.
