1 Choose a circuit breaker with time-current curves comparable to a Time Delay 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.
Y Caution: Failure to follow these fuse and circuit breaker recommendations could create an electric shock or fire hazard. These
recommendations are for a dedicated branch circuit that applies to the rated output and duty cycle of the welding power source.
