electrical junction box sizing 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®. A junction box, also known as an electrical junction box or junction can, is an enclosure that connects and splits electrical wires and cables. Junction boxes permit access to wiring for maintenance, inspection, and installation.

Find out how to use the NEC code to determine the size of the junction box that your application requires.
Do you know the NEC requirements for sizing junction boxes and pull boxes for conductor sizes 4 AWG and larger? Conductor damage during installation is one consequence of undersizing junction and pull boxes.By accurately sizing your junction box, you ensure compliance with safety standards, prevent potential electrical issues, and optimize space usage. The calculator takes into account several factors, such as the type of conduit, conductor size, and the number of conductors. Pull boxes, junction boxes, and conduit bodies must be sized to allow conductors 4 AWG and larger to be installed without damage to the conductor insulation. The NEC provides sizing requirements in Sec. 314.28.Boxes containing conductors of 4 AWG or larger, under 600V, are calculated from the sizes and numbers of raceways (see Figure 1). Where pull and junction boxes are used on systems over 600V, the installation must comply with the provisions in Part IV of Article 314.
Effortlessly calculate the required electrical junction box size for your wiring project using our Electrical Junction Box Size Calculator. Input the number of conductors and select the box type to get accurate results.
