If you have a metal box, use a screwdriver as a lever to remove the knockouts (the precut metal discs on either side of the box). You’ll also need to install cable clamps in the metal box. These thread into the box from the outside.
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 .
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®.Sizing of Junction and pull boxes according to NEC Section 314-28. Today, I will explain Electrical Boxes Volume and Fill Calculations as follows. Part (A), “Box Volume Calculations,” defines .
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 . You must size pull boxes, junction boxes, and conduit bodies large enough so a crew can install the conductors without damaging them. For conductors 4 AWG and larger, you size pull boxes, junction boxes, and .

Use this junction box sizing calculator to determine the recommended dimensions of a junction box depending on the number of straight and angle pulls entering it and meet the National Electrical Code®.
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. 1 ). 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®.Sizing of Junction and pull boxes according to NEC Section 314-28. Today, I will explain Electrical Boxes Volume and Fill Calculations as follows. Part (A), “Box Volume Calculations,” defines the volume of a wiring enclosure or box.
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.
You must size pull boxes, junction boxes, and conduit bodies large enough so a crew can install the conductors without damaging them. For conductors 4 AWG and larger, you size pull boxes, junction boxes, and conduit bodies per Sec. 314.28. Wondering how to size a junction box? Find out how to use the NEC code to determine the size of the junction box that your application requires.Determine the number and type of conductors entering and exiting the box. Include all devices, such as switches, receptacles, or splices, that will be housed within the junction box. According to NEC 314.16 (B), calculate the box fill units based on the conductor sizes and types. Each conductor, device, and fitting has a specific fill unit value.Enter the dimensions of multiple pull boxes to compare their sizes and capacities. This allows you to visually assess which pull box size best suits your project requirements, ensuring an informed decision. By specifying the cable diameter and material, you can calculate the minimum bending radius to prevent cable damage.
