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 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 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®. There is also a 1 inch conduit entering the bottom. So the 1" conduit is perpendicular to the 4" conduits. There is a splice within the box.
I am installing a new wall oven with 4 x10 awg wires encased in a Romex armored cable that is an inch thick. The typical (4x4) junction box's knockouts I can find is 1/2"-3/4". What kind of junction box can I find that has one inch knockouts? 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.
standard junction box sizes
For example, if the raceway installed is 3 inches, then 24 inches (3 × 8 = 24) is the minimum length of the pull or junction box. However, the size of the raceway and the number of conductors spliced or pulled through govern the width and depth. Standard North American junction boxes come in a variety of shapes and sizes (round, octagon, square, rectangular); however, most wiring devices intended for junction box mounting, save for light fixtures, are designed around the standard device yoke mounting pattern -- this is defined in NEMA WD-6 (an abridged version can be found here) as a 4 . 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.
The calculator processes these inputs to determine the required volume for the junction box. It uses a preset table of volumes per conductor size. For instance, entering an 18 AWG conductor size will yield a volume of 1.0 cubic inch per conductor. A junction box is not a special type of box but any standard electrical box used to enclose wire splices. The most commonly used box for junctions is a 4-inch square box (either metal or strong plastic), which offers ample space for making wire connections with multiple wires or .
