Distribution Box and Distribution Control Box
Distribution Box: Handles main supply voltage (220V–690V) with current ranging from tens to hundreds of amps. Junction Box: Mainly for low-voltage wiring (12V–240V) . What Is a Distribution Box? A distribution box, also known as a distribution board or panel, is the central unit that distributes incoming electrical power to various circuits. Located near machinery, they provide centralized control for starting, stopping, adjusting, and monitoring. Typical components, such as switches, buttons, and indicator lights, enable easy operation and display. What's the Difference Between an Industrial Distribution Box and a Control Cabinet? In factories and engineering projects, people often misunderstand: Despite both being metal enclosures containing electrical equipment, their functions, wiring structures, and internal components are completely. What is a Distribution Box? A distribution box, or DB box, is a circuit breaker enclosure.
