This calculator determines the minimum size of a pull box based on the number and size of conduits entering and exiting the box, as well as the type of pull (straight or angle). According to the NEC (National Electrical Code), different rules apply for straight and angle pulls. How to Use the Calculator
The volume of a wiring enclosure (box) shall be the total volume of the assembled sections and, where used, the space provided by plaster rings, domed covers, extension rings, and so forth, that are marked with their volume or are made from boxes the dimensions of which are listed in Table 314.16(A). Where a box is provided with one or more securely installed barriers, the volume .
314.16 Number of Conductors in Outlet, Device, and Junction Boxes, and Conduit Bodies. Boxes and conduit bodies shall be of sufficient size to provide free space for all enclosed conductors. In no case shall the volume of the box, as calculated in 314.16(A), be less than the fill calculation as calculated in 314.16(B). 6 in x 6 in x 4 in gives us a volume of 144 cubic inches. Converting to mL (144 divided by 0.061) gives us 2,360 mL. Now, if you have all 12 gauge, you can calculate the box fill for connecting one two wire bx to conductors from a conduit. That would be the same space as 5 conductors, given the two marrettes. That number is 143.5 mL.
