Where splices or where angle or U pulls are made, the distance between each raceway
entry inside the box or conduit body
and the opposite wall of the box or conduit body
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 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 312.6(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 314.28(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.
