There are four wires coming out of the generator, which should be three live wires and one neutral wire. One end of the three live wires is the live wire and the other end is grounded with the neutral wire.
How many wires are there in general generators? Each wire or terminal has required markings. After servicing the generator, the generator wiring must be connected correctly according to the markings.
When generator lead wires or terminals are not marked, or the markings are unclear, or the meaning of the markings is forgotten, the following methods can be used to identify the generator wires. earth.
1. Fire test method. When the generator is working normally, use a wire to scratch. If sparking occurs when a certain wire is scratched against the other two wires, then the wire is the ground wire and the other wires are for line of sight.
2. Voltmeter measurement method. When the generator is operating normally, connect the test lead on one end of the voltmeter to one of the lead wires and connect the other lead to the other lead wires. The voltage between the ground wire and the live wire is less than the voltage. between two live wires. For example, if the voltage between a certain wire and other wires is around 6 volts, the wire is a ground wire. If you don't have a voltmeter, you can also use a 12 volt bulb (the voltage is too low and the bulb is easy to burn out), connect it to the two lead wires and determine the voltage. depending on the brightness of the light. When the ground wire and the live wire are connected, the light is darker, and when the two live wires are connected, the light is brighter.
Is it dangerous if the live wire and neutral wire of a small single-phase generator are connected backwardss?
There is a potential difference between the two ends of the generator (i.e., the live wire and the neutral wire), and the neutral wire is grounded , i.e. 0 potential, the live wire becomes 220 V. As for why this is the case, it is because there must be a wire connected to ground. If it is not grounded it will be very dangerous (both wires have voltage relative to ground).
A light, a zero and two wires are connected to the house without distinguishing the neutral wire and the live wire. The ground wire is used for protection. For example, the electricity generated by the generator must be equipped. with a motor, and the ground wire is It should be connected to the motor shell. Of course, there must be a leakage protection switch between the generator and the motor. The fire and zero of the generator must be connected to the input. Leakage protection switch interface. The thread ofThe generator ground cannot be used as a neutral line. All high voltage electricity must be used according to regulations, otherwise it will be dangerous if you are connected to an earth that does not have one. voltage, do not connect it to your house. This could charge the generator hull, Danger! ! ! !
