For raceways containing conductors of 22 mm2 or larger, and for cables containing conductors
of 22 mm2 or larger, the minimum dimensions of pull or junction boxes installed in a raceway or
cable run shall comply with (a)(1) through (a)(3). Where an enclosure dimension is to be

made, the distance between each raceway entry inside the box and the opposite wall of the box
shall not be less than six times the metric designator (trade size) of the largest raceway in a row.
This distance shall be increased for additional entries by the amount of the sum of the diameters
of all other raceway entries in the same row on the same wall of the box. Each row shall be
calculated individually, and the a single row that provides the maximum distance shall be used.
Exception: Where a raceway or cable entry is in the wall of a box or conduit body opposite a
removable cover, the distance from that wall to the cover shall be permitted to comply with the
distance required for one wire per terminal in Table 3.12.1.6(a). The distance between raceway
entries enclosing the same conductor shall not be less than six times the metric designator
(trade size) of the larger raceway. When transposing cable size into raceway size in
3.14.2.14(a)(1) and (a)(2), the minimum metric designator (trade size) raceway required for the
number and size of conductors in the cable shall be used. (3) Smaller Dimensions. Boxes or
conduit bodies of dimensions less than those required in 3.14.2.14(a)(1) and (a)(2) shall be
permitted for installations of combinations of conductors that are less than the maximum conduit
or tubing fill (of conduits or tubing being used) permitted by Table 1 of Chapter 9, provided the
box or conduit body has been listed for, and is permanently marked with, the maximum number
and maximum size of conductors permitted.
All pull boxes, junction boxes, and conduit bodies shall be provided with covers compatible with
the box or conduit body construction and suitable for the conditions of use. Where used, metal
