For example, a box is needed for two 2-inch conduits. One conduit will enter the left side and the other will enter the bottom. Although the minimum size box required is only a 12-by-12, by using a larger box, the conduits can be centered (see Figure 6). Next month's column continues the discussion of pull- and junction-box calculations. EC The size of a pull box is determined by the size and amount of conductors, as well as the quantity and diameter of raceways. Pull boxes and junction boxes for conductors 4 AWG and greater must be sized in compliance with NEC article 314.28. We will include an explanation of the size guidelines for the most frequent sorts of pulls.

Variables may include: the size of conduit, number of cables, length of the conduit runs and whether flexible conduit is involved before it enters the pull box. Generally speaking, if the conduit is a 25 mm (1 in) with four (4) cables, then the conduit runs do not meet the standard, but the cable will probably not be damaged if care is taken ...

When determining conductor size for box-fill calculations, the AWG size in cubic inches is used. ... Sizing Pull Boxes and Junction Boxes — Over 1000 Volts Requirements for sizing pull boxes ...Once you know how many conductors you'll have in your pull box, you can determine the minimum dimensions using the following formula: length = 2 x width x height. For example, a pull box containing four 3/4-inch diameter conductors would require a minimum length of 9 inches (2 x 3 x 3).Once you know how many conductors you'll have in your pull box, you can determine the minimum dimensions using the following formula: length = 2 x width x height. For example, a pull box containing four 3/4-inch diameter conductors would require a minimum length of 9 inches (2 x 3 x 3).The calculation procedure would be as follows: Six times the largest raceway diameter = 6 x 4" = 24" Sum of all other raceway diameters = 2" + 2" = 4" Total = 24" + 4" = 28" In addition, the straight distance between the entry and exit points of each circuit must be six times the respective conduit diameter.If a circuit uses 3” conduit and uses a pull box for a U-turn, the procedure is as follows: Six times the largest raceway diameter = 6 x 3” = 18”. The sum of all the other raceway diameters = 3”. Total = 18” + 3” = 21”. The straight-line distance between the entry and exit point is just like in angle turns: six times the conduit ...
