If you want to make a ground wire by yourself in rural areas, you can follow the steps below. However, it should be noted that the self-made ground wire should comply with relevant electrical safety standards to ensure electrical safety.

# Prepare Materials and Tools
- **Materials**:
- **Grounding Electrodes**: You can choose steel pipes with a length of about 2.5 meters and a diameter of not less than 50 millimeters, or angle irons with a thickness of not less than 4 millimeters and a width of not less than 40 millimeters. You can also use round steel with a diameter of not less than 20 millimeters. Generally, the number is 3 - 5 pieces.
- **Flat Steel or Round Steel**: Used to connect the grounding electrodes. The flat steel should have a thickness of not less than 4 millimeters and a width of not less than 25 millimeters; the round steel should have a diameter of not less than 8 millimeters.
- **Tools**: Shovels, electric welders (used for welding the grounding electrodes and connecting the flat steel), hammers, tape measures, etc.

# Select the Grounding Location
- You should choose a place that is moist and has a low soil resistivity, such as areas close to wells, sewers, or low-lying areas prone to water accumulation. Avoid setting it in places with many stones and dry soil.
- Keep a certain distance from buildings, trees, etc. Generally, it should be no less than 1.5 meters away from the building foundation and no less than 1 meter away from trees.

# Install the Grounding Electrodes
- **Drill Holes**: Use a shovel to dig 3 - 5 holes at the selected location, with a depth of about 2.5 meters. The distance between the holes is generally about 3 meters, arranged in a triangle or a straight line.
- **Insert the Grounding Electrodes**: Vertically drive the prepared grounding electrodes into the holes, with the top protruding about 10 - 20 centimeters above the ground to facilitate subsequent connection. If the soil is hard, you can drive it in while watering.

# Connect the Grounding Electrodes
- Connect each grounding electrode with flat steel or round steel to form an integral grounding grid. Use welding for connection. The welding length requirements are as follows: when welding flat steel to flat steel, the welding length should be more than 2 times the width of the flat steel, and at least three sides should be welded; when welding round steel to round steel, the welding length should be more than 6 times the diameter of the round steel; when welding round steel to flat steel, the welding length should be more than 6 times the diameter of the round steel.
- After welding, remove the welding slag at the welding site and apply anti-rust paint to the welded parts to prevent rust and corrosion.

# Lead Out the Main Grounding Wire
- Lead out a piece of flat steel or round steel from the grounding grid as the main grounding wire and lead it to the vicinity of the equipment that needs to be grounded. The installation of the main grounding wire should be firm to avoid being damaged by external forces.

# Test the Ground Resistance
- Use a ground resistance tester to test the ground resistance. Generally, the ground resistance is required to be no more than 4 ohms. If the ground resistance does not meet the requirements, methods such as increasing the number of grounding electrodes, changing the position of the grounding electrodes, and adding a grounding resistance reducer around the grounding electrodes can be adopted to reduce the ground resistance.

# Connect the Equipment
- Reliably connect the grounding terminals of the electrical equipment that needs to be grounded to the main grounding wire. You can use bolt connection or welding methods. After the connection is completed, check whether the connection is firm to ensure good grounding.
During the process of making the ground wire by yourself, if you are not familiar with the operation or do not have relevant experience, it is recommended to consult professional electricians or staff of the power department to ensure the safety and reliability of the grounding system.
