Input Voltage (V) 230

Input Amperes (A) At Rated Output 54.9

Max Recommended Standard Fuse Rating In Amperes

Time-Delay Fuses

Normal Operating Fuses

−−

Max Recommended Input Conductor Length In Feet (Meters)

Min Grounding Conductor Size In AWG

Reference: 2014 National Electrical Code (NEC) (including article 630)

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” . 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).

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

310.15(B)(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.
