120V Fractional Motor Control Schematic and Layout

Materials

About this detail

The layout diagram shows the physical arrangement of a thermal switch, a relay (Functional Devices Inc. RIB2401SB), and a motor up to 0.75 horsepower maximum, connected by flexible conduit. The schematic diagram details the wiring connections using 120V AC or 24V AC/DC power, with specific wire color coding including white/black, white/blue, white/yellow, and orange conductors. An auto-off-on selector switch interfaces with the relay, while the thermal switch is wired in series with the control circuit. A note mandates that both the thermal switch and the relay must be mounted within sight of the motor being controlled.
