What does the protection rating of a distribution box mean? Distribution boxes are assigned an IP (Ingress Protection) rating, which indicates their resistance to dust and water. These safety components monitor the electrical flow continuously. When electrical problems occur—such as short circuits or excessive power draw—the circuit. The distribution box has the characteristics of small size, simple installation, special technical performance, fixed location, unique configuration function, not limited by the site, relatively common application, stable and reliable operation, high space utilization, less land occupation and. Its primary purpose is to ensure safe and efficient power distribution while providing protection via fuses or circuit breakers against overloads and short circuits. Distribution boxes are built with durable materials, typically metal or high-grade plastic, designed to endure environmental. The secondary distribution box should be placed 1. 5M above the ground The main switch is 60A Lighting switch 16A two-phase leakage switch Air conditioning 1. 5P-20A two-phase leakage switch Electric water heater 8000W+ washing machine - 60A two-phase leakage switch Socket switch 16A The main. It has a high level of safety protection and can visually display the conductivity status of the circuit.
