5-8. Electrical Service Guide

Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommenda- tions are for a dedicated branch circuit sized for the rated output and duty cycle of the welding power source.

	Input Voltage (V)	230

	Input Amperes (A) At Rated Output	20.5

	Max Recommended Standard Fuse Or Circuit Breaker Rating In Amperes
	Circuit Breaker 1, Time-Delay Fuses 2	25
	Normal Operating Fuses 3	30
	Min Input Conductor Size In AWG	14

	Max Recommended Input Conductor Length In Feet (Meters)	67
	Max Recommended Input Conductor Length In Feet (Meters)	(20)
		(20)

	Min Grounding Conductor Size In AWG	14

Reference: 2008 National Electrical Code (NEC) (including article 630)

1If 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).

4Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table 310.16. 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.
