Classification of Control and Distribution Boxes
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) . When it comes to electrical engineering, three types of enclosures often cause confusion among engineers, contractors, and procurement specialists: distribution boxes, control boxes, and junction boxes. At first glance, they may look similar—metal or plastic enclosures protecting electrical. Control Box: Control boxes manage the switching and operation of electrical equipment. Since metal distribution boxes have a higher protection level, metal ones are more widely used.
