Box fill applies to chapter 3 methods unless specified so, no. 314.16(B)1 only goes to 18awg so there would be no volume allowance to calculate box fill with something like UTP cat 5/6. There are raceway fill issues if medium powered.

Welcome to the forum.

Just curious, how many of what kind and size of wire, what else in the box, etc?
