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.

WARNING

Only a l ice nsed, c er t ified, tr a ine d e lect r ician 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 conju nction w ith the pr ope r ly r ate d 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 breaker. When the machine is operated in high temperature environ- ments, the breakers may tend to trip at lower loads than normally.

CAUTION

Never bypass the circuit breakers. Without over- loa d pr otec tion, the POWER -ARC 5500 could overheat and/or cause damage to the equipment being used.
