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.

WARNING

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.

CAUTION

Never bypass the circuit breakers. Without over- load protection, the POWERARC® 5500 could overheat and/or cause damage to the equipment being used.
