Power Distribution Box is an indispensable part of the electrical system, with the characteristics of compact structure, easy installation, safety and reliability. Its materials usually include metal box (such as cold-rolled steel plate, the surface is usually sprayed with plastic to enhance corrosion resistance) and internal conductive parts (such as copper or copper alloy busbars, circuit breakers, etc.). The advantage of the distribution box is that it can distribute electrical energy safely and efficiently, protect the circuit from overload and short circuit, and ensure the safety of electricity use. In addition, modern distribution boxes may also integrate intelligent components to achieve remote monitoring and automated management. Distribution boxes are widely used in various places, including residential, commercial buildings, industrial facilities, infrastructure, etc., to provide reliable power distribution and protection for various electrical equipment.
