Today, the small editor of the distribution cabinet manufacturer will introduce the difference between the zero row and the ground row in the civil distribution cabinet. Generally, the position of the zero row and the ground row in the distribution cabinet is not clearly specified during installation. Basically, the zero row is installed on the left side of the ground row. Of course, there are special circumstances, and the zero row and the ground row cannot be determined according to the installation position.
Generally, the number of terminal blocks of the zero and ground bars in a distribution cabinet is the same.
As we all know, the zero row is a straight row, and its two ends need to be connected with insulators during installation, and cannot be directly contacted with the box. However, the ground row is bent downward at both ends, with radians, and can be directly punched on the box during installation. Therefore, small objects in the distribution cabinet will cause major accidents if they are connected incorrectly.
When wiring, the upper port of the zero line is the lower port zero line of the main switch, so as long as the line from the lower port of the zero line can be the zero line branch of the lower port of the switch, and all lines are in parallel.
The shell of the power distribution cabinet is directly connected to the ground bar. Because the household power distribution box is a mounting box, it can also be directly connected to the ground as a ground bar. All the lines from the ground bar are. The role of the zero line is also very important. It is mainly to provide the zero line for the circuit breaker circuit. As mentioned before, the wrong connection of small items in the distribution cabinet will cause major accidents. The role of the ground bar is also important. The ground wire provides the ground wire for all socket circuits.
In the three-pin annoying socket, the upper socket is a device for electrical grounding. High-power electrical equipment will be equipped with grounding devices to prevent internal leakage and thus harm electrical equipment and users.
In short, both the zero line and the ground bar need to be grounded, but the purpose of grounding is different. When the neutral line is grounded, the neutral point is grounded at the transformer end. This is the neutral line. In a single-phase circuit, the connection between the neutral point and the grounding device obtains the reference zero potential of the earth. The neutral line is usually called the zero line. The grounding of the ground wire is inside the distribution cabinet. It is mainly used to eliminate the static electricity in the electrical appliance.
