Once a single-phase power circuit is loaded, the live wire has both current and voltage, while the neutral wire has current but no voltage, and all the voltage is consumed by electrical appliances. As the saying goes: the neutral line is dead.
Since the neutral line is directly grounded and has the same potential as ground, there is no voltage between the neutral line and ground, so people will not receive electric shock even if they touch the neutral line. This makes people think that the neutral line is that there is no electricity.
The live wire and neutral wire form a loop, the load works normally, and the ground wire plays a protective role in the event of electrical appliance leakage or human-made electric shock , the current. will flow into the earth through the ground wire, reaching the fu protection current valueites, if protection is missed, the circuit breaker will trip. Therefore, from a safety point of view, the ground wire cannot be used as a neutral line. If the ground wire is used as the neutral line, the circuit breaker will trip immediately if the protection fails.
Detailed information:
The practice of grounding without consideration will often result in harmful consequencestes for computer equipment. In severe cases, it will burn the entire application system of the equipment and even cause personal injury. Proper grounding can improve the anti-interference ability of the whole system.
The live wire, neutral wire, and ground wire are all wires connected to the three-hole jack. A sinusoidal oscillating voltage difference is maintained between the live wire and the neutral wire. Since the ground and neutral wires have the same potential, the voltage difference between the live wire and the ground wire also maintains a sinusoidal oscillation. When the human body contacts the live wire, the current from the live wire passes through the human body to the ground or neutral wire, and an electric shock accident occurs. However, you won't be electrocuted if you touch neutral. thread.
Connect the shell of electrical appliancesconnectors that can conduct electricity to the ground wire. In the event of a leak, current will flow directly into the earth through the earth wire without passing through the body, thus avoiding electric shock. accidents.

Push a clamp into the ground and connect it with live wire iron or ordinary wires You can make a neutral line, what is called a groundless series connection, but be careful not to use a leakage fuse. If the gate cannot be closed, simply use a molded case circuit breaker. If you must use a leakage circuit breaker. fuse, be sure to connect the neutral line. It can only be used after being warmed up. If you don't understand anything, ask me.
Your situation is as follows. It's easy to manage. Just pull the neutral wire. Your building is equipped with a lightning protection wire, orSteel grounding bar from the frame will do the trick. the connection does not need to be thick. You can use flat steel.
