shown in figure 5-31, view A. Figure 5-31, view B,
shows an example of how you can ground a single
receptacle in a circuit using a grounding clip.
Grounding the receptacle in this way bonds the box,
grounding wire, and receptacle, and precludes use of an
additional jumper wire.
Now that we have made the ground connections,
the next step of the finish work is to make terminal
connections. Properly made terminal connections are
important for several reasons. The operation of the
circuit, prevention of tire, and safety of personnel all
depend on good electrical connections. Electrical
connections must be electrically and mechanically
secure. There are two ways to make connections to
devices: with or without using a terminal loop. The
method of using the terminal loop and screw is shown in
figure 5-32. Some receptacles and switches are made so

that they can be wired from the back without using a
terminal loop. This method is shown in figure 5-33.
Now that you have made your terminal connections,
you install the device into its box and secure it with the
screws provided. The next step is to install the
receptacle cover plates. Cover plates will be installed
plumb, will completely cover the opening, and will be
seated against the mounting surface.
When installing switches for interior wiring, you
use single-pole, three-way, or four-way toggle switches.
Most of the switches you use will be single-pole, but
occasionally you will have to install a three-way
system, and on rare occasions, a four-way system. Still
another system of switching, called the low-voltage
system, is coming into use.
