PREMISES WIRING
The POWER-ARC 4000 three-wire, grounded neutral
generator allows it to be connected to premises
wiring. However, the wiring procedure needed to
meet the National Electric Code (NEC) regulations as
well as city ordinances can be confusing. Matters get
worse depending on whether you want the machine to
be “hardwired” to the premises or only connected
temporarily.
Only a licensed, certified, trained electrician should
install the machine to a premises or residential electri-
cal 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 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 POWER-ARC 4000 (unlike other Lincoln Electric
equipment) 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 4000 is intended
only for backup, intermittent use. The gasoline engine
has a rated life of 500 hours. It cannot withstand long-
term use without proper maintenance. See the MAIN-
TENANCE section of this manual for more informa-
tion.
Certain electrical devices cannot be powered by the
POWER-ARC 4000. Refer to Table A.2 for these
devices.
CIRCUIT BREAKERS
The POWER-ARC 4000 has its own
20 amp circuit breakers for overload
protection. When the machine is
operated in high temperature environments, the
breakers may tend to trip at lower loads than normal-
ly.
Never bypass the circuit breakers. Without overload
protection, the power-arc 4000 could overheat and/or
cause damage to the equipment being used.
