Wiring of neutral brass bar in the small power distribution unit

The wiring of the neutral brass bar in the small power distribution unit is an important electrical installation step, and its correctness directly affects the safety and stability of the circuit. The following is a brief explanation of the zero bar wiring inside the small power distribution unit:

1、 neutral brass bar position and installation

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

2、 Wiring steps

Preparation stage: Ensure that all tools and materials are complete, including insulated gloves, screwdrivers, wire strippers, insulated tape, and suitable wires.

Identification and Connection:

Identify the neutral wire of the incoming power supply, usually marked as "N".

Connect the neutral wire of the incoming power supply to the incoming terminal of the main switch.

Connect the neutral wires of all distribution circuits to the neutral terminal block. Note that the neutral wire here should not be connected to the wiring terminals of other non-zero wires.

Tightening and inspection:

Use a screwdriver to tighten the terminal block and ensure a secure connection.

Check all wiring for correctness, no omissions or incorrect connections.

3、 Precautions

During the wiring process, it is necessary to wear protective equipment such as insulated gloves to prevent electric shock.

After the wiring is completed, electrical safety testing should be carried out to ensure that the circuit has no safety hazards such as short circuits and leakage.

The small power distribution unit should be installed in a dry and ventilated place, away from flammable and explosive materials, to ensure the normal operation of electrical equipment and personnel safety.

In short, the wiring of the neutral brass bar in the small power distribution unit needs to be strictly carried out in accordance with electrical installation specifications to ensure the safety and stability of the circuit.
