5-16. Electrical Service Guide

Elec Serv 2011−08

Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These

recommendations 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.

NOTICE − INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of

input power at rated frequency(+10%) and voltage (+10%). Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a genera-

tor with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source.

. Actual input voltage should not exceed ± 10% of indicated required input voltage. If actual input voltage is outside of this range, output may not

be available.

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.
