Introduction – Sample of the Fast Trax® Program – We recommend the Fast Trax “Enhanced” Program – REVIEW HERE
Choosing the right type and size of box (or enclosure) is very important to installing a system essentially free from hazard. Article 314 covers a variety of provisions concerning boxes (outlet, device, pull, and junction), conduit bodies, and fittings. Box selection must be based on requirements for a given location (such as dry, damp, wet, or hazardous). Boxes have particular requirements concerning the maximum number of conductors. Boxes containing 6 AWG and smaller conductors are required to have a minimum cubic-inch capacity, which is determined by the size and number of conductors. Boxes containing 4 AWG and larger conductors are required to have a minimum height, width, and depth that is determined by the size and number of raceway entries. Article 314 contains provisions for installing, as well as supporting, boxes and conduit bodies. Boxes must be rigidly and securely fastened in place whether mounted on the surface, mounted to a framing member, or mounted in a finished surface. Under certain conditions, the only means of support a box needs is two threaded conduits. Access to conductors and devices located within boxes and conduit bodies must be available. Article 314 covers more information than the length of this book allows, such as manholes and boxes (pull and junction) for systems over 1000 volts, nominal.
