5-7. Electrical Service Guide

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

	60 Hz Single Phase
Input Voltage (V)	230 Volts AC	115 Volts AC
Input Amperes (A) At Rated Output	24
Max Recommended Standard Fuse Rating In Amperes 1		A 20 ampere
Time-Delay Fuses 2	30	individual branch
Normal Operating Fuses 3		circuit
	35	protected by

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.

5-8. Extension Cord Data (Use Shortest Cord Possible)

.When calculating max. cord length, remember to include conductor length from line disconnect device to input power receptacle.

	Input Power
Input Voltage	Phase	Hertz	Conductor Size	Max. Cord Length
115 V	1	60	14 AWG	25 ft (8 m)
115 V	1	60	12 AWG	55 ft (17 m)
115 V	1	60	10 AWG	100 ft (30 m)
230 V	1	60	14 AWG	53 ft (16 m)
