How to wire a gasoline generator safely
Dec 20,2022
The installation of the generator is very work, especially the wiring of the generator, which involves a lot of knowledge, so it is specially reminded for the generator users that the installation of the generator must be carried out by the person who needs to invite the RV generator.
To check the circuit: use a multimeter or electric test pen to measure and check the fire meter box to the AC switch box in the base station to confirm that the mains outside the base station is a normal power failure, the wiring in the oil generator switch box is correct, and there is no external power supply.
Then, after confirming the power outage, turn off other load circuit breakers (air conditioner circuit breakers, etc.) in the AC power distribution panel.
Third, according to the power-off process (low voltage first, then high voltage, first the load circuit breaker opens the diesel engine water pump and then isolates the circuit breaker) to cut off the power step by step: turn off the circuit breaker of the rectifier module in the switching power supply → turn off the mains input circuit breaker in the switching power supply → close Mains input circuit breaker in the AC power distribution panel → close the AC input main circuit breaker in the AC power distribution panel. Here, the consultant wants to popularize a knowledge: because the resistance and inductance of the motor winding itself are very small, the moment the motor starts, Equivalent to a short circuit, the current is quite large, and a reverse inrush current will also be generated when the motor is silent and the generator is turned off.
