Basic understanding of surge protection for distribution box

When using the distribution box, we should know that it is convenient to stop and transmit power, plays the role of measuring and judging the stop and transmission of power, an electrical equipment, when the circuit fails, it is also easy to repair. When the distribution box is in use, the surge protector will play a protective role, mainly to protect the electronic equipment from the "surge" damage. In fact, the concept of surge is if it exceeds the normal working voltage of the instantaneous overvoltage. Essentially, a surge is a violent pulse that occurs in just a few millionths of a second.

In the case of surge, only heavy equipment, short circuit, power switch or large engine will trigger the problem. In the home environment, this problem will not occur, mainly in some large production enterprises.
