Hello dear, I am very happy to answer your question. The HF-400GF diesel generator model is installed in parallel with two 300mm2 copper core cables of the same specification for each phase. The neutral line uses a 300MM2 and grounding. The wire uses 300mm2 single-core copper core cable can be installed. When selecting diesel generator cable, ensure that its load capacity (related to cross section) is not less than the safe load current to carry. The current carrying capacity of the cable depends on: (1) The material of the conductor - copper or aluminum (2) Insulating material (3) Characteristics of the protective layer - intermediate layer, armor or shielding (4) Ambient temperature (5 ) Installation method - The selection and installation of low voltage lines exposed, placed in trunking, buried or mixed with other lines must comply with the IEE or regulationsn local. For digital connections, standard cables must be used. (Please refer to relevant local regulations): (1) For distances less than 305 meters (1,000) feet, use number 20 multi-conductor stranded copper wire. (2) Above 305 meters and below 610 meters (2,000) feet, use number 18 multi-conductor stranded copper wire.
How do I connect the generator line of a gasoline engine? There are three lines on the generator. How should I connect it?
Diesel generators must be grounded. There must be a suitable ground wire. Once a leak occurs, a loop will occur with the earth, seriously affecting human safety.
Protective earthing of diesel generators is used in ungrounded three-phase power neutral point systems. Its function is that once the insulation of the electrical equipment isdamaged and a leak occurs, the human body comes into contact with the energized hull. At this time, the resistance of the human body is much greater than the resistance of the body to the ground (40). , and a large amount of point current escapes to the ground through the metal shell, and the ground voltage may drop below the safety voltage of 36V.
Its function is the following: When the insulation structure of a certain motor winding has been damaged and the shell is loaded, if it is not grounded and the human body touches the shell, it is equivalent to a single - electric shock phase, and a risk of electric shock may occur.
If protective grounding is used, when the human body touches the hull, the resistance of the human body is connected in parallel with the resistance of the earth since the resistance of the human body is much higher to the resistance of the earth. , the current trapouring into the human body will be very small and no danger of electric shock will occur.
Detailed Information
The following points should be noted when wiring the diesel generator set:
1. The ground wire connection point. is usually at The chassis end of the diesel generator set should be connected to a suitable ground wire location when installing the ground wire.
2. The alternator neutral ground wire connection is usually determined by the user during installation. When the diesel generator set is used as the sole power source, the neutral wire must be directly connected to the factory ground. thread.
3. For more complex installations, the grounding midpoint should be selected to ensure proper operation of the diesel generator set or protective equipment, such as fault detectionto earth and minimizing the circulating current to earth.
4. The ground wire must be arranged in accordance with the recommendations of the user and local authorities.
5. Ensure that the equipment wiring is always effectively maintained, and the maintenance of the wiring system should be strict.Follow the instructions.

Whether it is a gasoline generator or a diesel generator, the principle and generator power are the same.
There are two sets of coils inside the generator. One is the excitation coil, also called the magnetic field coil, which is used to generate a magnetic field after being energized. The other is also the armature coil. called rotor, which is generated by rotating and cutting magnetic lines of force. The circuit diagram of the generator is as follows:
As shown in the diagram ofcircuit, the generator output line has three terminals, namely the magnetic field terminal, the voltage output terminal and the ground wire. Terminal.
As shown in the figure, the magnetic field terminal should be connected to the magnetic field of the voltage regulator, and the voltage output is connected to the battery and electrical equipment.
