What wire is used for the grounding wire of local equipotential in the bathroom, is it a soft wire o

If you don't need to move the hard wire, you need to move the soft wire, the cross-section is not less than 6 square meters, which is required by the lightning protection specification, the grounding wire is directly connected to the earth's line, can also be called the safety return route, when it is dangerous, it will directly transfer the high pressure to the earth, which is a lifeline.

Grounding wire function: The high-voltage grounding wire is used for line and substation construction, in order to prevent the electrostatic induction electric shock or misclosing of the adjacent live body to ensure safety.

The grounding wire is a wire that directly connects to the earth, which can also be called a safety route, and when it is dangerous, it directly transfers the high voltage to the earth, which is a lifeline.

High-voltage grounding wire structure: The portable high-voltage grounding wire consists of an insulated operating rod, a wire clamp, a short line, a grounding wire, a grounding terminal, a busbar clamp, and a grounding clamp.

High-voltage grounding wire production process: excellent production process -- wire clamp and grounding clamp are made of high-quality aluminum alloy die-casting; The operating rod is made of epoxy resin color tube, which has good insulation performance, high strength, light weight, bright color and smooth appearance.

The grounding soft copper wire is made of multiple strands of high-quality soft copper wire, and is covered with a soft, high-temperature transparent insulation sheath, which can prevent the wear and tear of the grounding copper wire in use, and the copper wire can meet the fatigue test requirements to ensure the safety of operators in operation.

It is better to use a hard wire, but you can also use a soft wire.

The grounding wire is a wire that directly connects to the earth, which can also be called a safety route, and when it is dangerous, it directly transfers the high voltage to the earth, which is a lifeline.

Due to the poor insulation performance of household appliances or the humid use environment, the shell of the household appliances will have a certain amount of static electricity, and in serious cases, electric shock accidents will occur. In order to avoid accidents, a wire can be connected to the metal shell of the electrical appliance, and the other end of the wire is connected to the ground, and the grounding wire will bring static electricity into the ground and release it once the electrical leakage occurs. In addition, it is more important for electrical maintenance personnel to use the soldering iron to solder the circuit, sometimes because the electric soldering iron is charged and the integrated circuit in the electrical appliance is damaged.

Friends who use computers sometimes ignore the grounding of the main chassis, in fact, the grounding of the main chassis of the computer can prevent the occurrence of crashes to a certain extent.

Grounding wire in the power system:

It is an important tool to ensure that workers are guaranteed in the event of an unexpected voltage on equipment and lines that have been cut off. According to the ministerial regulations, the grounding wire must be. 25mm

The above bare copper flexible wire is made.

It is better to use a hard line, and a soft line can also be used for copy.

Grounding wires in the power system: It is an important tool to guarantee workers in the event of an unexpected voltage on equipment and lines that have been powered out. According to the ministry, the grounding wire must be made of bare copper flexible wire of more than 25mm2.

If you don't use it to move.

Use a hard line, and if you need to move it, you need to use a soft line, and the cross-section is not.

DAO is less than 6 square meters, which is required by the lightning protection back specification, but from experience, as long as your bathroom is not at the highest point of the whole building, you can use a wire with a smaller diameter, if it is not used for lightning protection, just for electrical grounding protection, the cross-section is not less than the diameter of the wire.

Not less than four square copper wires, hard wire construction is very inconvenient, but as long as the test resistance is within 3 ohms, it can also be.

There are no hard requirements, and the cross-section is larger, but we generally use four square meters for construction

It is better to use a hard wire, but you can also use a soft wire, which can be used.

It is better to use copper wire, 5 square is enough.

According to GB50169-2006 "Electrical Installation DU Installation Engineering Grounding ZHA Device Construction and Acceptance Specification DAO

It is stipulated that when copper wire is used for equielectric grounding, its cross-sectional area should not be less than.

In page 16 of 02D501-2 "Equipotential Installation", the equipotential grounding wire in the toilet is made of 4mm copper core wire.

The above copper core wire can be used.

The iso end of the bathroom is lightning protection and water heater leakage, with 4 square copper wires, soft and hard. It is connected to the exposed metal of the water pipe outlet. This is not an ordinary grounding wire, do not mix with the grounding wire.

If you don't need to move the hard wire, you need to move the soft wire, the cross-section is not less than 6 square meters, which is required by the lightning protection specification, but from experience, as long as your bathroom is not at the highest point of the whole building, you can use a smaller diameter of the line, if it is not used for lightning protection, just for electrical grounding protection, the cross-section is not less than the diameter of the electric line.
