This diagram shows two switches in the same box with two separate 120 volt sources. Three-wire cable is supplying the source for both switches with the black and red wires going to the bottom switch terminals. The black wire from each light is connected to the top terminal of their respective switch. The white and ground wires are spliced to run to each light fixture.
The black wire is splice to the output on the speed controller and to the black, fan wire at the other end. The red wire is spliced to the output on the dimmer and to the blue, light wire at the other end. The neutral from the source is spliced in the switch box with the white wire, and to the neutral wire on the ceiling fixture at the other end.
In this diagram multiple ground fault circuit interrupter receptacles are wired together using pigtails. Two-conductor cable is run between gfci’s, and the hot, neutral and ground wires from the source are spliced to the line terminals at each device. The load terminals are not used and each device provides its own, single-location protection.
This page contains wiring diagrams for two outlets in one box. Included are arrangements for 2 receptacles in one box, a switch and receptacle outlet in one box, and 2 switches in the same box. In this diagram, two duplex receptacle outlets are wired using pigtails spliced to connect the terminals of each to the source wires.
