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.
