Input Voltage
Input Amperes At Rated Output
Max Recommended Standard Fuse Rating In Amperes
Circuit Breaker
Min Input Conductor Size In AWG
Max Recommended Input Conductor Length In Feet (Meters)
Min Grounding Conductor Size In AWG
Reference: 2005 National Electrical Code (NEC) (including article 630)
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.
