- 1). Cut two 6-inch strips of wire using a knife. Remove about ¼ inch off the ends of the two strips of wire using wire strippers.
- 2). Connect one end of each of the two strips of wire to the terminal connectors on the transformer. You can usually unscrew the connector knobs using your fingers, or if the transformer has screw connectors, loosen the screws slightly using a screwdriver. Insert the wires under the connectors or screws and tighten them using your fingers or the screwdriver.
- 3). Plug in a transformer to your electrical socket. Transformers turn high voltage electricity into safe low voltage electricity. Turn on the power to the transformer. If your transformer has a variable voltage selection, then set it to the highest setting; it's only likely to be about 12 volts.
- 4). Hold one strip of wire from the transformer in one hand and the other strip of wire in the other hand. Touch the loose ends of the wires onto each other. You've made a short circuit as you have connected the positive and negative polarities together without and electrical device between them. The short circuit back-ups to the electrical socket then to the fuse box or trip switch within a millisecond and your fuse blows, or the cut-off switch trips.
- 5). Remove the wires from each other. Turn off the transformer. Reset the trip switch, or replace the fuse.
