In this diagram wall outlets are wired in a row using the terminal screws to pass voltage from one receptacle to the next. Wiring outlets together using the device terminals, instead of a pigtail splice as shown in the next diagram, can create a weakest-link problem.. Wiring Diagram for Multiple GFCI's. In this diagram multiple ground fault.. This diagram illustrates wiring a GFCI receptacle and light switch in the same outlet box, a common arrangement in a bathroom with limited space.. If wall receptacle circuits operated like that, you wouldn't be able to plug an appliance in down stream from another appliance in the same circuit because the voltage wouldn't be sufficient to.
