What is the difference between the relay box and the distribution box?
Relay box is a secondary line control box, distribution box is a line power supply control box.
A line power supply that the power supply through the switch or other device power supply load circuit, the secondary line that the power supply through the other device power supply load control circuit.
In the power system, usually according to the role of electrical equipment will be divided into a device and secondary equipment. The primary equipment refers to the electrical equipment that is used for the production, transportation and distribution of electrical energy, including generators, power transformers, circuit breakers, disconnectors, bus bars, power cables and transmission lines. The secondary equipment is a low-voltage electrical equipment for monitoring, controlling, measuring, regulating and protecting the working conditions of power systems and primary equipment, including measuring instruments, control of primary equipment, operation monitoring signals, and automated monitoring systems. Protection and safety of automatic devices, communications equipment. Secondary equipment according to certain functional requirements connected together constitute the electrical circuit referred to as the secondary wiring or called the secondary circuit, it is to ensure that the power system safe production, economic operation and reliable power supply is an indispensable part
