Can the neutral wire and ground wire of the small power distribution unit be shared?

The neutral wire and ground wire of the small power distribution unit cannot be shared. Neutral and ground wires play different roles in power systems.

The neutral wire is the circuit's return path, which carries current from the consumer back to the source. It usually carries a voltage, but under normal conditions, it should be close to zero.

The ground wire is used for safety purposes and is used to connect the casing of electrical equipment to the ground to prevent personal injury in the event of equipment leakage or failure.

If the neutral wire and the ground wire are shared, it will cause serious safety hazards. In the circuit, the functions and purposes of the neutral wire and the ground wire are different, and sharing them will cause current confusion, increase the risk of electric shock, and may cause damage to electrical equipment. Therefore, in order to ensure the safe operation of the power system, the neutral wire and the ground wire must be used strictly separately and cannot be confused.
