When the load is a resistive load such as incandescent, heater or common power tools, using
electrical appliances can refer to rated power. If the load is inductive and resistive mixed loads
such as fluorescent lamps, mercury lamp, transformers, fans, small blowers or inductors,using
electrical appliances can only refer to 60% rated power.
NOTICE: WHEN GENERATOR REACH OPERATING SPEED THEN CAN ADD LOAD .
The following table list shows some household electrical appliances’ power for reference.

(a) Cold to start the motor need 5-7 times rated current.
(b) Because the temperature of the compressor head requirements 15 minutes after restarting
6.2 START ELECTROMOTOR
When start electromotor need large current, some electromotor especially phase motor with low
power is hard to start and needs 5-7 times running current. Capacitor start motor needs 2-4 times
running current. Permanent magnet motor need 1.5-2.5 times running current.
When overloaded, the generator will not run basis on the power characteristic curve, the rotate
speed of diesel engine doesn’t increase, which couldn’t output enough power to drive
electromotor to reach the working speed. The generator could make a response on a large initial
starting current. However, a sharp decline in engine speed, may cause generator stop. If allowed
to run with a very low speed, the motor windings will be ablated in a very short time, in this low
speed operation it could lead to the stator and motor windings burn out soon. Because of starting
a large current just a moment, When the generator speed quickly rises to the operating speed,
