240-Volt AC devices may be fitted with either a
three-pin 15 Ampere (typically abbreviated "15 Amp"
or "15 A") plug or a three-pin 10 Ampere ("10 Amp"
or "10 A") plug as shown in Figure 17. Certain
double-insulated devices may be fitted with a two-
pin 10 A plug that doesn't have an earth pin (which
is the longer, vertical pin).

NOTICE
DO NOT connect any 240-Volt AC device that is
fitted with a three-pin 20 A plug. This can overload
the generator.
See 240-Volt AC Extension Cords for detailed
instructions concerning their selection and use.
12-Volt DC Loads
12-Volt DC devices can be connected either directly
or via an electrical extension cord not exceeding
3.5 m in length into the 12-Volt DC outlet on the
generator's control panel. Pull out the weather
resistant stopper on the outlet for access to connect
the electrical accessory or cord, and re-insert it after
use.
12-Volt DC devices or extension cords must be
fitted with a cigarette lighter plug for connection to
the generator as shown in Figure 18.

Power Output and Demand

There are two limits to the amount of electric power
that the generator can usefully provide: (a) its total
240-Volt AC or 12-Volt DC electric power generating
capacity or power output and (b) the electric current
or power output capacity of each individual 240-Volt
AC or 12-Volt DC outlet.
The generator's total power output measured in Watts
is listed in the Specifications. Two 240-Volt AC power
outputs are specified for the generator, namely the
running power and the starting power. The 12-Volt DC
power output is also specified.
B - 10 Ampere
DO NOT overload the generator's 240-Volt AC or
12-Volt DC circuits beyond their rated capacities.
This can result in damage to the generator or to
the connected devices.
The generator should not be run completely unloaded
for extended periods otherwise the engine may be
damaged. It is recommended that the generator
should always be operated with at least one-third of
its rated 240-Volt AC power output.
240-Volt AC devices have two different electric power
demands that must be taken into consideration,
namely the running power and the starting power. Both
are measured in Watts (typically abbreviated as "W").
The steady state continuous load is the running power
demand and this is often marked on the device near
its model number or serial number. Sometimes the
device might only be marked with its voltage (i.e. 240
Volt or 240 V) and current draw (e.g. 6 Ampere or 6
Amp or 6 A), in which case the running power demand
in Watts can be obtained by multiplying the voltage
times the current, e.g. 240 V × 6 A = 1,440 W.
Simple resistive 240-Volt AC devices such as
incandescent bulbs, toasters, heaters, etc. have no
extra power demand when starting, and so their
starting power demands are the same as their running
power demands.
More complex 240-Volt AC devices containing
inductive or capacitive elements such as electric
motors have a momentary extra power demand when
starting, which can be up to seven times the running
power demand or more. Manufacturers of such
devices rarely publish this starting power demand and
so it's often necessary to estimate it.
OPERATION
WARNING
Never insert an automotive cigarette
lighter into the 12-Volt DC outlet. The
heated lighter may ignite the fuel
causing an explosion or fire.
