Wiring method of neutral bar in the small power distribution unit

The wiring method of the neutral bar in the small power distribution unit mainly follows the following steps and principles:

Position determination: In the small power distribution unit, the neutral bar is usually located on the left side and installed on an insulated base to ensure safety.

Prepare the wires: Prepare the corresponding wires according to the combination of the main switch and the sub switch in the small power distribution unit. Ensure that the color and specifications of the wires comply with safety standards, usually the neutral wire is light blue.

Wiring operation:

For the main switch with a leakage protector, separate the small power distribution unit without a leakage protector, and directly connect the neutral wire of the incoming power supply to the incoming terminal of the main switch, and then connect it to the neutral bar through a wire.

The neutral wire terminal of the branch switch is usually not directly connected to the neutral wire, but is connected to the common neutral bar on the shell.

When wiring, ensure that the wires are tightly connected, do not damage the core, do not run continuously, and follow the principle of horizontal and vertical wiring.

Identification and inspection: After wiring is completed, label each wire with its name and purpose for subsequent maintenance and repair. At the same time, check if all wiring is secure and there are no exposed conductors to ensure safety.

Sorting and Cleaning: Sort the wires inside the small power distribution unit into bundles, tie and fix them with plastic ties, and keep the box clean and orderly. At the same time, remove debris and dust from the box to ensure a good operating environment for the equipment.

Following the above steps and principles can ensure the smooth wiring of the neutral bar in the small power distribution unit and ensure the safe and stable operation of the power system.
