7. Procedure
The steps that follow describe how to install electrical switches and receptacles.
Before you begin, use a neon circuit tester to be sure that the circuit is dead and that no power is entering the box.

8. Step 1
When wiring several receptacles in a row, use the layout shown here.

9. Step 1
The last receptacle in the run is connected like the one on the right.

10. Step 1
All the others are wired like the two on the left. Two-wire cables are used.

11. Step 2
Receptacles in a bathroom or kitchen must be covered by a GFCI (ground fault circuit interrupter). A GFCI protects against electrical shock.

12. Step 2
The connection below gives shock protection, not only to the GFCI receptacle, but also to the receptacles that follow it on the circuit.

13. Step 2
To install a GFCI:
Connect the wires from the power source to the “line” screw terminals.

14. Step 2
Connect the wires going out to the “load” screw terminals. Two-wire cables are required.

15. Step 3
A light and switch at the end of a circuit are connected as shown here. This is the simplest light and switch combination.

16. Step 4
A switch loop occurs when the switch is at the end of the cable run. In this case, both the black and white wires are hot with current at the switch.

17. Step 4
Mark the white wire in the cable that connects to the switch with black tape at both ends, or paint it black to indicate that it is hot.

18. Step 5
If a switch and light are in the middle of the circuit, connect them as shown here.

19. Step 6
It is often desirable for a light to be controlled from two different locations. This requires the installation of three-way switches.
Three-way switches can be wired in three different ways. The wiring methods are shown on the following slides.
