The grounding wire is a safety protection device.

The main function of the grounding wire is to introduce current into the earth when electrical equipment leaks or is induced to be charged, so as to avoid electric shock and equipment damage. For example, in a household circuit, one of the holes of a three-hole socket is connected to the grounding wire. When the electrical appliance leaks, the current will flow into the earth through the grounding wire instead of through the human body.

In an industrial environment, large electrical equipment and machines have special grounding wires. For example, the outer shell of the distribution box in the factory will be connected to the ground wire. In this way, once the circuit inside the distribution box fails and the outer shell is charged, the current will be immediately released through the ground wire to prevent workers from being electrocuted.

The ground wire has the following main advantages:

Safety guarantee

- Prevent electric shock accidents: When electrical equipment leaks due to insulation damage, failure, etc., the ground wire can quickly introduce the current into the earth to prevent the human body from being electrocuted when touching the outer shell of the equipment. For example, if an electric water heater with grounding is used, if the water heater leaks, the current will flow into the earth along the ground wire instead of flowing through the human body, which greatly guarantees the personal safety of the user.

- Protect equipment safety: It can effectively prevent electrical equipment from being damaged by overvoltage, static electricity accumulation and other factors. In thunderstorms, a good grounding system can introduce the strong current generated by lightning into the earth to prevent electrical equipment from being damaged by lightning.

Signal stability

- In electronic equipment and communication systems, the ground wire can be used as a reference potential for the signal, which helps to reduce electromagnetic interference and stabilize the signal transmission of the equipment. For example, in a computer room, good grounding can make the communication signals between servers and other equipment more stable and reduce data transmission errors.

Compliance with standards and specifications

- In most countries and regions, the installation of electrical systems requires effective grounding wires, which is an important standard for safety and quality. Compliance with these standards can ensure the legality of the system, and also facilitate the equipment to pass safety certification, enhancing users' confidence in the safety of the equipment.
