PREMISES WIRING
The WELDANPOWER 125 three-wire, grounded neu-
tral 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 tem-
porarily.
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 WELDANPOWER 125 does not have a combined
115/230 volt twist-lock receptacle and cannot be con-
nected to a premises as described in other Lincoln lit-
erature.
Remember that the WELDANPOWER 125 is intended
only for backup, intermittent use. It cannot withstand
long-term use without proper maintenance. See the
Maintenance section of this manual for more informa-
tion.
Certain electrical devices cannot be powered by the
WELDANPOWER 125. Refer to Table A.2 for these
devices.
CIRCUIT BREAKERS
The WELDANPOWER 125 has its own
20 amp circuit breakers for overload
protection (15 amp CSA). 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 overload
protection, the WELDANPOWER 125 could overheat
and/or cause damage to the equipment being used.
