The choice of the electric cable depends on the allowable current of the cable
and the distance between the load and the generator. And the cable section
should be big enough.
If the current in the cable is bigger than the allowable current, it will become over
hot and the cable will be burnt. If the cable is long and thin, the input voltage of
the electric appliance will be not enough, causing that the generator doesn't start.
In the following formula, you can calculate the value of the potential "e".
The relations among of the allowable current, and length, section of the Insulating
cable (single core, multi-core) are as follow:
(Presume that the use voltage is 220V and the potential is below 10V.
Gasoline is extremely flammable and explosive under certain conditions.
Refuel in a well ventilated area with the engine stopped.
Keep away from cigarette, smoke and sparks when refueling the generator.
Always refuel in a well-ventilated location.
Wipe up spilled gasoline at once.
Restrict application of generator in high-hazard risk to causing fire area.
Connections for standby power to a building's electr-
ical system must be made by a qualified electrician
and must comply with all applicable laws and electri
cal codes. Improper connections can allow electrical
current from the generator to back feed into the utility
lines.Such back feed may electrocute utility company
workers or others who contact the lines during a
power outage, and when utility power is restored,
the generator may explode, burn, or cause fires in
the buildings electrical system.
Always make a pre-operation inspection before you start the engine. You
may prevent an accident or equipment damage.
Place the generator at least 1m(3ft) away from buildings or other equip-
ment during operation.
Operate the generator on a level surface. If the generator is tiled, fuel
spillage may result.
Know how to stop the generator quickly and understand operation of all the
controls. Never permit anyone to operate the generator without proper
instrucions.
Keep children and pets away from the generator when it is in operation.
Keep away from rotating parts while the generator is running.
The generator is a potential source of electrical shocks when misused; do
not operate with wet hands.
Do not operate the generator in rain or snow and do not let it get wet.
