Correct Connection Method Of Grounding Wire Of Distribution Box

The correct connection method of Distribution box grounding wire mainly includes the following steps:

1. Find the grounding bar or PE bar

Open the distribution box and find the position marked with the grounding plate or PE letter. This position is the connection point of the grounding wire in the box.

2. Connect the power ground wire

Connect the ground wire in the power supply directly to the corresponding wiring port. Generally, copper core wire is selected as the ground wire and connected to the PE wiring bar. When connecting, it is necessary to strip the wire for a distance, then connect it to the terminal, and tighten the screw with a screwdriver to ensure a firm connection.

3. Grounding of electrical components

If there are electrical components in the distribution box that need to be grounded, copper core wires can be used to connect these components to the PE bar to ensure the safe operation of the electrical equipment.

4. Other precautions

Ensure that the grounding connection is reliable and no looseness occurs, and the connection should be clearly marked for daily inspection and maintenance.
When connecting the ground wire, a yellow-green insulated copper core soft wire with a cross-sectional area not less than the specified value should be used. This wire not only has good conductivity, but its yellow-green double-color outer skin also plays an obvious warning role. If a grounding device needs to be designed, it should be ensured that the grounding device complies with relevant specifications and requirements to achieve an effective grounding effect. Following the above steps and precautions can ensure the correct connection of the distribution box grounding wire, thereby ensuring the safe operation of electrical equipment and the safety of personnel.
