The distribution box is the same as the control box
While distribution boxes, control boxes, and junction boxes may appear similar, their roles within electrical systems are entirely different. Distribution boxes ensure safe and efficient power distribution. Each outgoing line can be individually. The most direct way to distinguish them is by looking at: voltage level, control logic, and physical size. It is usually wall-mounted or embedded in the wall. Located near machinery, they provide centralized control for starting, stopping, adjusting, and monitoring.

Can wiring in a distribution box be bent at right angles
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. The bend radius is the radius of the circular curve made (radius) when you bend a wire back onto itself. 6 (A) applies where conductors do NOT enter or leave the enclosure through the wall opposite their terminals. During installation, cables are bent or flexed in various environmental conditions (Sometimes bent way too far!).
