Matching different electrical appliances requires considering their startup peak power and normal operating power. The peak power and rated power of the generator are crucial factors. Peak power represents the maximum instantaneous power that the generator can provide, while rated power indicates the continuous power output of the generator, typically at 90% of the peak power.

When selecting a generator, it's essential to base your choice on the startup peak power of the appliances rather than solely considering their normal operating power. This is because many appliances require more power during startup and then operate at lower power levels during normal operation. If you only consider the normal operating power of the appliances, you may choose an undersized generator, which could result in the appliances not starting properly.

Specifically, electrical appliances can be categorized as follows:

1. Resistive Load: Appliances with resistive loads typically require roughly the same power during both startup and normal operation. Examples include electric heaters or light bulbs.

2. Inductive Load: Appliances with inductive loads require more power during startup and then operate at lower power levels during normal operation. Examples include electric motors.

3. Capacitive Load: Appliances with capacitive loads may require more power during startup and then maintain a stable power level during normal operation. Examples include some electronic devices.

When selecting a generator, you should consider the peak power requirements of all connected appliances to ensure that the generator's rated power is sufficient to meet these needs. Additionally, you should account for scenarios where multiple appliances are connected simultaneously to ensure that the generator has enough peak power and rated power to meet the demands of all the appliances.

In summary, understanding the power requirements, types, and concepts of peak power and rated power for electrical appliances is crucial for selecting the right generator to ensure that your appliances operate correctly and receive the necessary electrical support.
