THE FUSE.
The next important step in show window wiring is the proper fusing of circuits. The fuse is to the lighting wire what the safety valve is to the steam boiler. A fuse is composed of a fusible metal, which contains lead, zinc, etc., and becomes fusible at a certain degree of temperature. The fuse is supposed to be “the watch dog” of safety. Ninety-five per cent of the electrical fires are caused by improper fusing.
My advice to the amateur is to apply to the nearest office of the National Board of Fire Underwriters for a copy of the rules on incandescent wiring. They may be obtained for the asking.
