Are there any regulations regarding the dimensions of electrical distribution boxes
You must size pull boxes, junction boxes, and conduit bodies large enough so a crew can install the conductors without damaging them. That means the minimum dimensions of boxes and conduit. NEC Article 314 establishes requirements for the installation and use of electrical boxes, conduit bodies, fittings, and handhole enclosures. A conduit body is a removable-cover section of a conduit system that provides access at junctions or termination points. Understanding the common sizes available and their typical applications will. Section 314.
