5-10. Electrical Service Guide

Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda-
tions are for an individual branch circuit sized for the rated output and duty cycle of one welding power source.
In individual branch 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 Maximum total length of copper input conductors in entire installation, raceway and/or flexible cord.
5 Raceway 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) and is based on allowable ampacities of insulated copper conductors having a temperature rating of 75°C (167°F) with not
more than three single current−carrying conductors in a raceway.
