Pull Box Calculator. The National Electric Code (NEC) specifies a minimum size for pull, junction box and conduit bodies. The code specifies this based on whether it is a straight pull or the conductor turns in an angle or u pull. The code treats a splice internal to the box the same as an angle or u-pull.
Determining the size of underground pull and junction boxes to meet NEC 314.16 code standards is required to prevent damage to conductor insulation. Calculating the correct size of pull box needed can be complicated, so please feel free to contact us or call 800-767-1576 if you need assistance.
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.
Effortlessly calculate the required electrical pull box size for your wiring project using our Electrical Pull Box Size Calculator. Input the number of conductors and select the box type to get accurate results.
Use 314.28 (A) to size pull boxes, junction boxes, and conduit bodies when using conductor sizes 4 AWG and larger. Suppose you have a 2-inch raceway coming into a 10-inch square box, and a 2-inch raceway leaves it on the opposite side.
Use this box fill calculator to find the correct size of electrical utility box to fit the conducting wires, grounding wires, and devices or equipment you would need to install and have it pass the National Electrical Code®.
When sizing pull boxes and junction boxes, follow these suggestions: Step 1: Organize and always draw out the problem. Step 2: Calculate the horizontal distance(s):
