NOTE :

1.Appliances equipped with electric motors.

They need large starting current as mentioned above. However after starting, the appliance requires only 1.2 to 2 times the wattage to continue running.Therefore, the generator has reserve power for another appliance.

2.Some appliances will indicate output work instead of (input) wattage.

Example : 40W fluorescent lamp means 40W of the light beam is emitted from the lamp.

In such case, efficiency should be considered between the (input) wattage and output work,

Efficiency

0.6to 0 . 8 . . . . motor

0.7to 0.8. . . . fluorescent lamp

The (input) wattage determined by the efficiency subjects to the same as above.

3.Voltage drop in long extension wires

When a long wire is used to connect an appliance with the generator, a certain amount of voltage drop occurs in the wire which lessens effective voltage to the appliance.
