5、 the Horsepower rating for the newly created ANS/NEMA receptacle configurationsL25-30R and L26-30R. The horsepower test current (locked rotor amperes) is based upon UL 508 Table45.2, full-load motor running currents in amperes for single-phase and Table 45.4 for locked-rotor motorcircuits for 3-phas
6、e ratings. For full-load motor running current, single phase (UL 508, Table 45.2) lockedrotor amperage is 6 times fullload current.Copyright 2016 UL LLCUL LLC, in performing its functions in accordance with its objectives, does not guarantee or warrant thecorrectness of Certification Requirement Dec
