AUXILIARY POWER RECEPTACLES, PLUGS, AND HAND-HELD EQUIPMENT

The control panel of the GX-271 features three auxil- iary power receptacles: See Figure B.1.

•Two 15 amp, 120 volt duplex (double outlet) recepta- cles.

•One 50 amp 120/240 volt single outlet receptacle.

Through these receptacles the machine can supply up to 8,000 rated continuous watts of single-phase, 60 Hz AC power.

For further protection against electric shock, any elec- trical equipment connected to the 120V duplex recep- tacles must use a three-blade, grounded type plug or an Underwriter’s Laboratories (UL) approved double insulation system with a two-blade plug. Lincoln offers an accessory plug kit that has the right type of plugs. See the ACCESSORIES section of this manual for more information.

If you need ground fault protection for hand-held equipment refer to the K896-1 GFCI Receptacle kit in the ACCESSORIES section of this manual for more information.

For recommended extension cord lengths and sizes see Table A.1.

CIRCUIT BREAKERS

The GX-271 machines are equipped with 50 amp cir- cuit breakers on the 120/240 V receptacle and 15 amp circuit breakers on the 120 receptacles for overload protection. Under high heat a breaker may tend to trip at lower loads than it would normally.

CAUTION

Never bypass the circuit breakers. Without overload protection, the GX-271 could overheat and/or cause damage to the equipment being used.

PREMISES WIRING

The GX-271 is suitable for temporary, standby, or emergency power using the engine manufacturer’s recommended maintenance schedule. With its three- wire grounded neutral generator, it can be permanent- ly installed as a standby power unit for 240 volt, three wire, single phase 33 ampere service.

WARNING

Only a licensed, certified, trained electrician should install the machine to a premises or residential elec- trical system. Be certain that:

•The installation complies with the National Electrical Code and all other applicable electrical codes.

•The premises is isolated and no feedbacking into the utility system can occur. Certain state and local laws require the premises to be isolated before the generator is linked to the premises. Check your state and local requirements.

•A double pole, double throw transfer switch in con- junction with the properly rated double throw circuit breaker is connected between the generator power and the utility meter.

------------------------------------------------------------------------

The following information and the connection diagram, Figure A.1, can be used as a guide by the electrician for most applications to premises wiring.

1.Install a double pole, double throw switch between the power company meter and the premises dis- connect. The switch rating must be the same as or greater than the premises disconnect and service overcurrent protection.

2.Take the necessary steps to assure that the load is limited to the capacity of the GX-271 by installing a 35 amp 240 volt double pole circuit breaker. Maximum rated load for the 240 volt auxiliary is 33 amperes. Loading above 33 amperes will reduce output voltage below the allowable -10% of rated voltage. This may damage appliances or other motor-driven equipment.

3.Install a 50 amp 120/240 volt plug (NEMA type 14-

50)to a double pole circuit breaker using No. 8 or larger, 4 conductor cable of the desired length. (The 50 amp 120/240 volt plug is available in the optional power plug kit.

4.Plug this cable in to the 50 amp 120/240 volt recep- tacle on the GX-271 case front.
