NOTE 1: Running amps are for the highest demand portion of the cycle, after the motor is up to speed, and are approximate.
NOTE 2: Use Bussmann Fusetron FRN (up to 250V), FRS (250 to 600V) or similar lag type fuses.
CORRECT FUSE MUST BE USED—Never use fuses other than those specified. Extract mo-
tor may take up to two minutes to fully accelerate basket, during which time motor draws
nearly locked rotor current.
NOTE 3: Use wire size shown for runs up to 50 feet (15 meters). Use next larger size for runs 50 to 100 feet (15 to 30 meters). Use wire
two sizes larger for runs greater than 100 feet (30 meters).
CORRECT WIRE SIZE MUST BE USED—Never use wire of a smaller size than specified.
Smaller wire—even though its current-carrying capacity may be greater than the required
fuse—may cause voltage drops, thereby reducing starting torque. (A 5% voltage drop
causes motor to produce only 90% of its rated torque.) Note that the voltage drop is greatest
the instant the motor is energized, and thus when the highest torque is required.
NOTE 4: See section MSSM0118AE “FUSE AND WIRE SIZING” for more information.
