4-12. 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.

Reference: 2005 National Electrical Code (NEC)

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” .

3 “Normal Operating” (general purpose - no intentional delay) fuses are UL class “K5” (up to and including 60 amp), and UL class “H” ( 65 amp 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

310.16. 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.

4-13. Placing Jumper Links

Ref. 802 295

Tools Needed:

3/8 in

Do not overtighten

jumper link nuts.

! Disconnect and lockout/tag-

out input power before

installing or moving jumper

links.

Check input voltage available at

site.

1 Jumper Link Label

Check label − only one is on unit.

2 Jumper Link

Move jumper links to match input

voltage, and label on unit.

Close and secure access door, or

go on to Section 4-14.
