1. the role of electrical grounding wire, and precautions!
the function of the household grounding wire is to prevent the leakage current of the household appliances from leaking into the earth through the grounding wire, so as not to threaten the safety of human life. since the resistance value of the grounding wire is not more than 4ω, it is far lower than the normal resistance value of the human body 2000ω, so leakage current will not flow into the earth through the human body, but will flow into the earth through the grounding wire, thereby protecting the safety of people and equipment. this is the role of protecting the grounding wire.
electrical outlets must have protective grounding wires
2. matters needing attention!
a. the lighting line at home must be equipped with a leakage protector and a protective grounding wire. the leakage protector and the grounding wire are our lifeline, so they must be installed.
b. leakage protector please check the leakage test button once a month to see if it is sensitive and reliable. if it is damaged, it should be replaced in time to ensure that the equipment will not threaten the safety of people and equipment when the equipment leaks.
a 2p leakage protector must be installed in the home to ensure safety
