Standby Power Connections - Lincoln Electric VANTAGE 300 IM992 Operator's Manual

A-8
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 VANTAGE® 300 is suitable for temporary, stand-
by or emergency power using the engine manufactur-
er's recommended maintenance schedule.
The VANTAGE® 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 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 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 allow-
able - 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.
