Table 314.16 (B) gives the volume required for each conductor of a given size. As you can see, each AWG 12 conductor required 2.25 IN3 (Cubic Inches). So, if a box has to hold the following conductors—four No. 14, four No. 12, and two No. 10 conductors—the math is pretty simple. Four No. 14 @ 2.0 IN3 = 8.0 IN3. Four No. 12 @ 2.25 IN3 = 9.0 IN3.Table of Electrical Box Sizes vs Number of Wires Allowed.
