Thanks

Canadian NMD90 is rated for 300 volts and has a reduced size ground wire in #12 and #10 sizes. I think it's also made without paper filler.

Prevents the plastic from filling in all the space between the wires.

I once thought it was there to "insulate" the bare EGC.

Is it only available in Canada?

It would not serve a purpose here so I doubt it is stocked around here.

You could likely get it via Amazon.

It doesn't meet NEC requirements, so no.

The suffix B in NMB indicates that the conductors inside are rated at 90 degrees C.

See the informational note to 334.112

Informational Note: Types NM, NMC, and NMS cable identifed
by the markings NM-B, NMC-B, and NMS-B meet this requirement.
