This diagram illustrates the wiring for a circuit with gfci receptacles followed by an unprotected light and switch. The light switch is connected directly to the source and the load terminals on the gfci are not used.
This page contains wiring diagrams for ground fault circuit interrupter (gfci) receptacles. Included are diagrams for multiple gfci’s, a protected standard duplex receptacle, and a protected light fixture. Wiring for a switch and gfci receptacle in the same box is also shown to protect the switch and light or to protect other receptacles in the circuit. To wire a gfci circuit breaker see this link and wire a gfci switch combo at this link.
Splice both the fan and the light hot wires together with the common wire from the SW2. The traveler wires are spliced together in the ceiling fixture box. To control the fan and light separately, a builtin switch such as a pull chain or remote control is required on the fan/light.
The black cable wire is connected to the top terminal on the switch and spliced to the black and blue wires at the fan at the other end. The neutral source and ground are spliced through to the white and ground connections at the fan.
