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. Located near machinery, they provide centralized control for starting, stopping, adjusting, and monitoring. In industrial production, the speed, temperature, pressure, etc. Its main job is to take the incoming power supply and distribute it to multiple circuits within the building, ensuring that electricity is delivered safely to different areas.
