INSTALLATION
CROSS COUNTRY 300
AUXILIARY POWER RECEPTACLES
Start the engine and set the “IDLER” control switch to the “High Idle”
mode. Voltage is now correct at the receptacles for auxiliary power. This
must be done before a tripped GFCI can be reset properly. See the
MAINTENANCE section for more detailed information on testing and
resetting the GFCI.
The auxiliary power of the CROSS COUNTRY 300 consists of two 20
Amp-120 VAC (5-20R) duplex receptacles with GFCI protection, one
50 Amp 120/240 VAC (14-50R) receptacle and one 50 Amp 240VAC
Three-Phase (15-50R) receptacle.
The auxiliary power capacity is 11,500 watts Peak, 10,000 Watts
Continuous of 60 Hz, single phase power. The auxiliary power
capacity rating in watts is equivalent to volt-amperes at unity power
factor. The max permissible current of the 240 VAC output is 42amps.
The 240 VAC output can be split to provide two separate 120 VAC
outputs with a max permissible current of 42 Amps per output to two
separate 120 VAC branch circuits (these circuits cannot be
paralleled). Output voltage is within ± 10% at all loads up to rated
capacity.
The Three-Phases auxiliary power capacity is 12,500 watts peak,
11,000 watts continuous. The maximum current is 27 amps.
120 V Duplex Receptacles and GFCI
A GFCI protects the two 120V auxiliary power receptacles.
A GFCI (Ground Fault Circuit Interrupter) is a device to protect against
electric shock should a piece of defective equipment connected to it
develop a ground fault. If this situation should occur, the GFCI will trip,
removing voltage from the output of the receptacle. If a GFCI is tripped
see the MAINTENANCE section for detailed information on testing and
resetting it. A GFCI should be properly tested at least once every month.
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.
All auxiliary power is protected by circuit breakers. The 120V has 20 Amp
circuit breakers for each duplex receptacle. The 120/240V
Single Phase and the 240V Three-Phases have a 50 Amp 3-pole
Circuit Breaker that disconnects both hot leads and all Three Phases
simultaneously.
STANDBY POWER CONNECTIONS
The CROSS COUNTRY 300 is suitable for temporary, standby or
emergency power using the engine manufacturer’s
recommended maintenance schedule.
The CROSS COUNTRY 300 can be permanently installed as a standby
power unit for 240 VAC, 3 wire, single phase, 40 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 premises 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 generator by installing a 50 amp, 240 VAC double pole circuit
breaker. Maximum rated load for each leg of the 240 VAC
auxiliary is 50 amperes. Loading above the rated output will
reduce output voltage below the allowable - 10% of rated voltage
which may damage appliances or other motor-driven equipment
and may result in overheating of the 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 receptacle on the
case front.
