1 115 V 10 A AC Receptacle
Power is shared between duplex
receptacle and internal 14 socket
receptacle.
2 Circuit Breaker CB1
3 Circuit Breaker CB2
CB1 protects duplex receptacle
and 115 volts ac portion of internal
14 socket receptacle
overload.
Press button to reset breaker.
CB2 protects 24 volts ac portion of
internal 14 socket receptacle from
overload.
Press button to reset breaker.
4 Circuit Breaker CB1
CB1 protects the motor control
circuitry from overload. If CB1 trips,
