** Most ohmmeters will not give accurate readings when measuring less than 1 ohm. The stator can be considered good if a low resistance
reading (continuity) is obtained and there is no evidence of shorted windings (discoloration). Do not confuse a low resistance reading with a
reading indicating a shorted winding.
DERATION: All units are rated 1.0 power factor.
Derate approximately 3.5% per 1000 ft. (300 m) above
