NOTES: Wiring between generator and electrical appliances
1. Allowable current of cable
Use a cable with an allowable current that is larger than the rated input current of the load
(electrical appliance). If the input current is larger than the allowable current of the cable
used, the cable will become excessively heated and deteriorate the insulation, possibly
burning it out.
The table below shows cables and their allowable currents for your reference.
2. Voltage drop in long electric extension cords
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 available to the appliance.
The table below has been prepared to illustrate the approximate voltage loss when an
extension cord of 300 feet (approx. 100 meters) is used to connect an appliance or tool to
the generator.
R means resistance (
Ω/100 m) on the above table.
l means electric current through the wire (A).
2 means the length of the wire (m).
The length of the wire indicates round length, it means twice the length from generator to electrical
tools.
