Electrician Explains Electrical Codes for Home Electrical Junction Boxes with Photos, Wiring Diagrams and Answers to Your Questions Among other wiring installation details, the electrical code specifies how electrical outlets should be spaced and which types of outlets to use in general living areas, bathrooms, kitchens, and other 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. Boxes containing 6 AWG and smaller conductors must be sized in an approved manner to provide free space for all conductors, devices, and fittings. In no case can the volume of the box, as calculated in Sec. 314.16 (A), be less than the volume requirement as calculated in Sec. 314.16 (B). Surface-mounted electrical boxes for all electrical fixtures must be raintight/weatherproof. Exterior light fixtures do not require GFCI protection. Low-voltage lighting systems must be listed by an approved testing agency as an entire system or assembled from individual components that are listed. The rules for pull boxes, junction boxes, and outlet boxes cover five areas. In summary: Minimum size [314.28(A)]. These requirements constitute most of Sec. 314.28. One key point is that on straight pulls the box or conduit body length must be at least eight times the trade size of the raceway.
