Requirements for the bending angle of wires in distribution boxes
This rule, found throughout multiple NEC articles (for instance, Article 358. 26 for PVC), specifies that the total angle of all bends between any two pull points—such as junction boxes, conduit bodies, or cabinets— must not exceed 360 degrees. In practice, that. The National Electrical Code (NEC) provides specific requirements for conductor bending space, cable installation, and cabinet dimensions to ensure safe and compliant installations. A conduit body is a removable-cover section of a conduit system that provides access at junctions or termination points. Includes straight-pull, angle-pull, U-pull, and splice-box examples with real dimensions. Pull boxes and junction boxes are easy to underestimate because the conductors already fit in the conduit on paper.
