The Ground Wire Connection Of The Copper-clad Ground Rod Should Be Paid Attention To
copper bonded earthing connection should be noted
1. Old houses do not necessarily need copper bonded steel
Newer buildings have grounding systems, so copper bonded steel ground rod must be connected during decoration. If you buy a second-hand house with a house age of more than 25 years, most of them do not have a grounding system, so copper bonded steel rod is not needed. Only when the building itself has a grounding design, the home copper clad ground rods will have a safety function, otherwise, the electricity cannot be introduced into the ground.
2. The electrical box also needs copper coated earthing rod
In the high-voltage distribution box, there will be two rows of copper bars, one copper plated ground rod and the other copperbond earth rod. If you encounter a shoddy master, he will not connect it. You should check it specially when connecting the electrical box.
3. How to determine if there is earth bonding rod in the socket at home
Cut off the main power supply, find a long wire, a flashlight bulb, and a large battery. Insert one end of the long wire into the ground wire hole of other sockets, connect the battery and the bulb to the other end, and insert the other end of the bulb into the ground wire hole of the socket to be tested. Use the ground wire in the house to make a loop. If the bulb lights up, there is no problem, proving that the ground wire is connected. If it does not light up, it means that the ground wire is not connected. The ground wire holes of all sockets in each room should be tested. 4. The specific role of the ground wire Protective role: The outer shell of the electrical equipment is connected to the ground wire through the plug, and the socket is connected to the ground wire. Once there is a leakage, the outer shell of the electrical equipment will be charged, but due to the role of the ground wire, the outer shell of the electrical equipment is guaranteed to be at the same potential as the ground wire, that is, the voltage to the ground is equal to 0, thus ensuring the personal safety of the electrical user.

Anti-leakage: A three-hole socket with a ground wire can ground the outer shell of the washing machine and refrigerator, protecting people from electric shock in the case of leakage. When an electrical appliance leaks electricity, the current directly enters the earth through the ground wire, preventing people from getting electric shock when touching the appliance. The ground wire is directly connected to the earth, and the resistance between it and the earth is much smaller than the resistance of the human body, so the ground wire is very important.
