PREMISES WIRING
The POWER-ARC 5500 three-wire, grounded neutral
generator allows it to be connected to premises
wiring. However, the wiring procedure needed to
meet the National Electrical Code (NEC) regulations
as well as city ordinances and can be confusing. The
connections could vary from a "commonly grounded"
to a "separately derived" system depending on
whether you want the unit to be "hard wired" or tem-
porary to the premises.
Only a licensed, certified, trained electrician
should install the machine to a premises or resi-
dential electrical system. Be certain that:
• The premises is isolated and no feedbacking
into the utility system can occur. Certain state
and local laws require the premises to be isolat-
ed before the generator is linked to the premis-
es. Check your state and local requirements.
• A double pole, double throw transfer switch in
conjunction with the properly rated double
throw circuit breaker is connected between the
generator power and the utility meter.
The POWER-ARC 5500 does not have a combined
120/240 volt twist-lock receptacle and cannot be
connected to a premises as described in other
Lincoln literature.
Remember that the POWER-ARC 5500 is intended
only for backup, intermittent use power. Oil level must
be checked after every 5 hours of use. It cannot with-
stand long-term use without proper maintenance.
See the MAINTENANCE section of this manual and
the engine owner’s manual for more information.
Certain electrical devices cannot be powered by the
POWER-ARC 5500. Refer to Table A.2 for these
devices.
CIRCUIT BREAKERS
Auxiliary power is protected by circuit breakers.
When the machine is operated in high temperature
environments, the breakers may tend to trip at lower
loads than normally.
Never bypass the circuit breakers. Without over-
load protection, the power-arc 5500 could over-
heat and/or cause damage to the equipment being
used.
