POWERARC® 5500
PREMISES WIRING
The POWERARC® 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 connec-
tions could vary from a "commonly grounded" to a
"separately derived" system depending on whether
you want the unit to be "hard wired" or temporary 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 feed backing
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 POWERARC® 5500 does not have a combined
120/240 volt twist-lock receptacle and cannot be con-
nected to a premises as described in other Lincoln lit-
erature.
Remember that the POWERARC® 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
POWERARC® 5500. Refer to Table A.2 for these
devices.
CIRCUIT BREAKERS
Auxiliary power is protected by circuit breaker. When
the machine is operated in high temperature environ-
ments, the breakers may tend to trip at lower loads
than normally.
Never bypass the circuit breakers. Without over-
load protection, the
PPOOWWEERRAARRCC®®
5500 could
overheat and/or
cause damage to the equipment
being used.
