This diagram illustrates the wiring for multiple ground fault circuit interrupter receptacles with an unprotected duplex receptacle at the end of the circuit. The load terminals on the gfci are not used and the last receptacle is wired directly to the circuit source.
This is the updated wiring for this arrangement, with a 2-wire cable added between the fan/light and switches. The white wire is no longer used for hot and the source neutral is run through to the switch box to satisfy the 2011 NEC requirement of a neutral wire in all switch boxes. All other wiring is the same as above.
Here GFCI’s are wired to a double-pole circuit breaker with the source split to provide 120 volts to two sets of receptacles. The neutral from the source is shared by both sets. Single-location protection is provided by each receptacle.
This diagram illustrates the wiring for a Cooper gfci/switch combo device wired to protect a garbage disposal. With this arrangement a receptacle, switch and disposal are protected with the ground fault breaker built into the device.
