Industrial Electronics for Engineers, Chemists, and Technicians: With Optional Lab Experiments

Obtain a power cord with an attached plug, either two- or three-prong. If it has already been soldered onto a transformer, cut it free by using the wire stripping tool as a scissors, close to its rotatable hinge.
On both the wires of the power cord, strip off the insulation, to about 3/4 inch (or about two centimeters) from the ends. This is done in the following manner. Use the wire stripper as if it was a scissors, but place the wire farther from the rotatable hinge, so the wire falls down into the pair of V-grooves. Try to cut into the plastic (or rubber) insulation, but not into the copper metal wire itself. (More resistance to the cutting action will be felt when you begin to hit the metal.) Release your grip on the tool, and the spring should open the tool's blades (jaws) part of the way if not, open the blades yourself, part-way. Keep the tool at the same place on the wire, lengthwise. Rotate the wire about 45 degrees, and cut down into the insulation again, trying not to cut the metal. Release, rotate, and cut again, several times, so the cut you have made goes all around the insulation, separating the last 3/4 inch cylinder of insulation from the rest of it.
While keeping the blades closed part-way down into the round cut you have just made (but not pressing onto the metal very much), strongly push the tool toward...
