Not applicable for 3020 M7G, M7J, M7P.
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 motor 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.
