This guide provides a practical breakdown of pull box sizing rules as per NEC Article 314, focusing on different pull configurations and calculations engineers should consider. In angle pulls, conduits enter and exit from adjacent sides of the pull box. NEC requires the distance from the entry. The sizing requirements for pull boxes, junction boxes, handhole enclosures, and conduit bodies exist to prevent conductor insulation damage. Those requirements are in 314. 28, and they apply to all conductors 4 AWG and larger (Fig. Proper sizing ensures conductors can be installed without damage and allows for proper bending space. How Does the Calculator Work? The calculator uses NEC 314. When installing insulated conductors of 4 AWG or larger, the minimum dimensions of pull or junction boxes installed in a raceway or cable run must comply with 314. 28 (A) (1) through (A) (3). Keep in mind these requirements address conductors used for general wiring, such as those. NEC Article 314. Minimum Length = 8 × Largest Conduit Size Minimum Dimension = 6 × Largest +.
