SOME “DON’TS.”
Don’t be negligent in handling your connections. Insulate every joint, and don’t leave loose joints; they consume too much current.
Don’t cross wires that are insulated without bushing the overlying wires, and never cross uncovered wires.
Don’t bring a wire through the floor or back of window without using clay bushings; that’s what they are for.
Don’t run wires (as in Fig. 8) without using a lamp, or cutting wires where X is marked; it saves a short circuit.
Don’t let the wires to your lamps touch brass, except under the screw.
Don’t attempt to connect your design to your “cut-out” until you are sure your switch is open. You may short circuit yourself. It is not necessarily fatal, but is decidedly unpleasant.
Don’t handle live wires; 110 volts won’t kill you, but through carelessness you may some day touch a stronger circuit. Practice caution.
Don’t leave an uncovered wire to show in your window. If you suspend a design, wrap the wires with the same color as your background.
Don’t imagine you are an electrician because you can run a string of lights. Keep digging away; you’ll learn something every day.
