nm means non-metallic referring to the outer covering of romex cable. Can't remember what the b is. AWG is the wire gauge
of the wires in the cable. 14-2 nm-b would be 14 guage (awg) wire in a non-metallic (romex) cable. Sure I'm forgetting something, so standby for a pro to expound.

the b is the temperature rating

The b is the temperature rating, 90 degrees C.

Thanks, Bob, if I ever knew that I've forgotten it long time ago.
