NEMA Control - Freedom Series - Single-Phase

Set motor horsepower slider to desired rating and read motor information under the proper line voltage. Full load amps based on the 2008 NEC Table 430.248 - fuse and breaker amps per 430.52. If a conduit contains 4-6 conductors, derate the ampacity to 80% per 310.15(B)(2) and Table 310.15(B)(2)(a).
