Use this wiring when the source is at the fixture and you want to control the feed to both components with the same switch. Three-wire cable runs from the fan to the switch box and the source neutral is spliced to the white wire and to the fan neutral.
In this diagram wall outlets are wired in a row using the terminal screws to pass voltage from one receptacle to the next. In this diagram, multiple receptacles are connected together using the device, instead of a pigtail splice as shown in the next diagram. Using this method, any break or malfunction at one outlet will likely cause all outlets that follow to fail as well.
The white wire is wrapped with black tape to identify it as hot. The black wire connects the fan to the speed controller. The red wire connects the light to the dimmer.
In this arrangement with 2 switches in one box, the bottom terminals are connected to pigtails spliced to the source. The top switch terminals connect to the black wires running to the light fixtures. The source neutral and ground wires are spliced to run to each light box.
