Abstract
An open fuse block is provided having a visual indicator or light assembly connected in parallel with a replaceable fuse mounted in the fuse block. When the fuse is blown, the corresponding visual indicator is illuminated to identify the blown fuse, thereby facilitating quick and easy replacement of the fuse. Since the visual indicator is connected in parallel with the fuse element, when the fuse is blown, the fuse results in an open circuit and the flow of electricity is rerouted through the visual indicator. The visual indicator is thereby illuminated and the corresponding blown fuse can be easily identified. The visual indicator or light assembly can include, for example, a neon bulb, light emitting diode, fluorescent bulb, incandescent bulb, or any other visual indicator that emits light.
