Despite the fact that the wires within nm-b cable are thhn wire and feature insulation rated for ninety degrees c, many versions of the code, inclusive of 2011 nec phase 334-80, limit ampacity of non-metalic cables including nm-b to no greater than that authorised with an insulation rated for 60 degrees c (probably due to warmness retention through the thick outer % jacket, despite the fact that they do no longer explicitly say that is the cause):.

Up via 10ga all of the copper wires have the same score but then they begin to diverge. I'm in particular surprised that there may be a exceptional among nm-b cable and thhn wires... Do not nm-b cables use thhn wires because the individual conductors?.
The cutting-edge wearing ability of twine and cable is decided with the aid of (1) the warmth produced because of conductor resistance, (2) the excessive temperature limit of the insulation used, and (3) the surroundings of the wire to the diploma it traps heat in the insulator (the whole lot which includes insulation thickness, conduit, proximity to a hot roof, and so on.). Gadgets (1) and (2) are characteristics of the wire. Item (three) is a function of each the cord and the set up. Your question is alternatively large. Assuming ampacity is what you're inquisitive about determining, usually it isn't decided by using one components. A unmarried strand of cord can also have a certain allowable current at stp, depending on the insulation and conductor kind. That can be derated based totally at the most ambient temperature, most altitude, and bundling with other wires. There can be other constraints that have to be happy (requirements and policies, voltage drop limits, fuse score and many others).
