NOMINAL power, or the ability that a generator can produce for a longer period of time, this is the power of the generator as a designated power, take into account that this is 90% of the maximum power, some companies advertise with this power which is pure distortion of competition . Let us take as an example that 4.2 kW generator, during a short time you can give a power of 4200 + 400 watts = 4600 watts, this generator is best used for a maximum power of 4000 watts, so in lamps expressed 40 lamps of 100 watts, also because the usage curve of your engine is at full height at full load
In the previous example, the lamps are the LOAD of the generator. A 4200 Watt generator can handle a maximum load of no more than 4600 Watts.
The “lamps” example is called a RESISTANT type of load and the required power is easy to understand. Other RESISTANT types of load are things like toasters, convection ovens, hobs, curlers, coffee makers, stereos and TVs. RESISTANCE LOAD is usually applied in appliances without electric motor. Resistance load = 1 x Power.
RESISTORS & REACTIVE TAX:
Another cake is the reactive load, this usually involves an electric motor. Some household appliances such as cooking fires and refrigerators have internal fans that operate intermittently, therefore additional power is required to start the fan. Another example is electrical tools. A device or tool with a REACTIVE load may need up to three times more power (KW) to START than it needs when walking.
