Ground-Fault Sensor Connection
The ground fault wires are in one of two configurations
depending on the circuit breaker type. One has the wires exiting
the circuit breaker and ending at the ring terminals; go to step
8. The other requires a connection of the receptacle and the
plug, which are keyed for ease of installation; follow steps 6 to
8.
6. Align the connector receptacle and the plug, as shown in
Figure 6. Mate the plug with the receptacle by pushing
them t ogether until the plug retention clip locks into the
receptacle.
