4-7. Electrical Service Guide

NOTICE − INCORRECT INPUT POWER can damage this welding power source. Phase to ground voltage shall not exceed +10% of rated input
voltage.
NOTICE − Actual input voltage should not be 10% less than minimum and/or 10% more than maximum input voltages listed in table. If actual input
voltage is outside this range, output may not be be available.
Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda-
tions are for a dedicated circuit sized for the rated output and duty cycle of the welding power source.
In dedicated circuit installations, the National Electrical Code (NEC) allows the receptacle or conductor rating to be less than the rating
of the circuit protection device. All components of the circuit must be physically compatible. See NEC articles 210.21, 630.11, and
630.12.

1 If a circuit breaker is used in place of a fuse, choose a circuit breaker with time-current curves comparable to the recommended fuse.
2 "Time-Delay" fuses are UL class "RK5" . See UL 248.
3 "Normal Operating" (general purpose - no intentional delay) fuses are UL class "K5" (up to and including 60 amps), and UL class "H" ( 65 amps and
above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.15(B)(16). If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable
requirements.
