WIRING AUTOQUIP "SUPER TORQUE' MOTORS
Because Autoquip "Super-Torque" motors actually deliver substantially more
horsepower than their nameplate rating, they must always be wired for heavier current-
draw than standard motors of the same nameplate rating. However, because of the
"Super-Torque" motors starting efficiency and superior running characteristics, circuit
components do not have to be as large as for standard motors of equal delivered
horsepower.
The following chart should be observed in connecting these motors to power
sources, remembering that, where 115-Volt operation is contemplated, the current-
draw is too heavy for plugging into ordinary lighting circuits. Heavy wire must be
used all the way to the power-source.
NOTE: For larger horsepower motors, consult factory.
