According to the referenced API standard in the guide, special purpose induction motors covered by API STD
541 are:

• A.375 kW (500 hp) and larger
• B.250 hp and larger
• C.100 hp and larger
• D.1000 kW and larger only

According to API 541, prior to mechanical running test, each mounting foot shall be checked for "soft feet." How is this check conducted?

• A.Feeler gauges are used at the foot to base interface to verify gap tolerance has not been exceeded
• B.Mounting bolt torque is verified with a calibrated torque wrench with no visible gaps observed between the foot and base interface
• C.After torquing mounting bolts, a vertically oriented, zeroed, dial indicator is attached to each foot and a reading taken after loosening of the bolt torque to verify movement is within tolerance
• D.A dial indicator is oriented vertically and zeroed prior to base bolt tightening with a reading taken after tightening to confirm movement is within tolerance

Within the context of NEMA ICS 1, which of the following describes PD 3?

• A.Moisture does not occur, always dry, dust insignificant and no effect from pollution
• B.Moisture occurs frequently, dust quantity is sufficient to become conductive when moist, and pollution is sufficient to cause tracking or erosion at a moderate rate
• C.Moisture occurs occasionally, dust quantity is sufficient to become conductive when moist and pollution is sufficient to cause tracking or erosion at a slow rate
• D.Moisture occurs continuously, dust quantity becomes conductive when moist, and pollution is sufficient to cause tracking and erosion at a high rate
