Reference: 2005 National Electrical Code (NEC) (including article 630)

1Choose 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).

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.

NOTICE − This unit is either a 200/230/460 ac input voltage model or 460/575 ac input voltage model. See rating label on unit and check voltage available at site to be sure it matches the voltage specified on the rating label.
