How to connect a single-phase generator to a three-phase network?
We have at the entrance to the house 3 phases 25 A - a city network. In a house for heating an electric boiler 3 phases of 9 kW (the possibility of limiting power from 1 kW to 9 kW in increments of 1 kW), as well as other household single-phase consumers with a total capacity of 4 kW. In the village, the lights are periodically turned off, and therefore a gas-gasoline single-phase electric generator with a maximum power of 7.5 kW and a rated power of 7 kW was purchased.
It is required to connect the generator to the house’s electric network with the ability to manually select the house’s power supply from the city network or from the generator, and then manually start it, and it is necessary that the boiler be powered from it (the boiler power for the period of emergency power from the generator will be limited manually up to 4 kW).
Please tell me what it is necessary to buy electrical equipment and a circuit for connecting power sources (main city network 3 phases, backup generator 1 phase) and consumers (boiler 3 phases, light 1 phase, household appliances 1 phase)
You can simply install another set of circuit breakers for light (1 phase) and a three-pole circuit breaker for the boiler (also short the upper terminals with a jumper), but then it is important not to forget to turn off the input before applying voltage to the boiler. By the way, how is your grounding connected? according to what scheme?
