Wires
The Circuits Experiment Board can be used with a large
variety of wire types and sizes. We recommend 20 or 22
gauge solid wire with colorful insulation. This will help
students to follow their work more easily and minimize
difficulties in making the transition from paper circuit to
actual circuit on the Circuits Experiment Board.
Stripping Your Own Wire
The wire included with the Basic Electricity Lab is 22
gauge insulated, solid wire in 5" and 10" lengths. The
lengths are stripped at each end.
If you choose to strip your own additional wires, a
commercially available wire stripper can be used to
remove the insulation from each end. The jaws of the
wire stripper are placed on the wire 3/8" from the end.
By squeezing the handles together, the jaws will close on
the wire and cut only as deep as the insulation.

Pulling the wire away from the stripper (Figure 2c) causes
the cut end of the insulation to slip off of the wire, leaving
3/8" of exposed wire.
If you do not have access to a wire stripper, the wire may
also be stripped by carefully using a knife. Place the wire
on a solid surface. Set the knife blade on the insulation
about 3/8" from the end. With the blade at an angle so it
cannot cut downward into the wire, use the knife to shave
off the insulation.
After one part of the insulation is removed, turn the wire
and continue shaving off the rest of the insulation.
