You need to determine the correct horizontal dimension, vertical dimension, and spacing between the raceways containing the same conductors. If you follow the steps laid out in Sizing Steps, you'll find this easy to do. For example, a box that contains three to six conductors requires a minimum volume of 18 cubic inches, while a box that contains seven or eight conductors requires a minimum volume of 20 cubic inches. Section 370-29 outlines the requirements for junction boxes used in hazardous locations. 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. When electrical cables route from box to box, you must leave at least six inches of free conductor wiring in the junction box for connection purposes. In article 300.14, this technique is explained.
