Connector Insert There is still a big difference between protective grounding and protective earth. In fact, this is also a commonplace topic. In any electronic website or any book about low-voltage power distribution, there will be N related topics and instructions, which is also a hot topic for electricians and engineers in architectural design institutes. 1. What is grounding: There are two types of grounding, one is working grounding and the other is protective grounding. The purpose of protective grounding is to obtain zero potential of the ground, and protective grounding is for personal safety. International and national standards for grounding: The international standard is IEC60364, and the national standard is GB16895.
