• Do not cross the welding cables at the output
terminal connection. Keep the cables isolated
and separate from one another.

AUXILIARY POWER RECEPTACLES
The auxiliary power of the RANGER 305G consists of
two 20 Amp-120 VAC (5-20R) duplex receptacles and
one 50 Amp 120/240 VAC (14-50R) receptacle. The
240 VAC receptacle can be split for single phase 120
VAC operation.
The auxiliary power capacity is 9,000 watts of 60 Hz,
single phase power. The auxiliary power capacity rat-
ing in watts is equivalent to volt-amperes at unity
power factor. The max permissible current of the 240
VAC output is 38 Amps. The 240 VAC output can be
split to provide two separate 120 VAC outputs with a
max permissible current of 38 Amps per output to two
separate 120 VAC branch circuits (these circuits can-
not be paralleled). Output voltage is within ± 10% at
all loads up to rated capacity.
The 120 V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs. The current
rating of any plug used with the system must be at
least equal to the current capacity of the associated
receptacle.
NOTE: The 240 V receptacle has two 120 V circuits,
but are of opposite polarities and cannot be paralleled.
STANDBY POWER CONNECTIONS
The RANGER 305G is suitable for temporary, standby
or emergency power using the engine manufacturer’s
recommended maintenance schedule.
The RANGER 305G can be permanently installed as
a standby power unit for 240 VAC, 3 wire, single
phase, 38 amp service. Connections must be made
by a licensed electrician who can determine how the
120/240 VAC power can be adapted to the particular
installation and comply with all applicable electrical
codes.
• Install the double-pole, double-throw switch
between the power company meter and the premis-
es disconnect. Switch rating must be the same or
greater than the customer’s premises disconnect
and service over current protection.
• Take necessary steps to assure load is limited to
the capacity of the RANGER 305G by installing a 40
amp, 240 VAC double pole circuit breaker.
Maximum rated load for each leg of the 240 VAC
auxiliary is 38 amperes. Loading above the rated
output will reduce output voltage below the allow-
able - 10% of rated voltage which may damage
appliances or other motor-driven equipment and
may result in overheating of the RANGER 305G
engine and/or alternator windings.
• Install a 50 amp, 120/240 VAC plug (NEMA Type
14-50) to the double-pole circuit breaker using No.
6, 4 conductor cable of the desired length. (The 50
amp, 120/240 VAC plug is available in the optional
K802R plug kit or as part number T12153-9.)
• Plug this cable into the 50 Amp, 120/240 Volt recep-
tacle on the RANGER 305G case front.
