Patent #7,683,752

A fuse box system that combines a series of specially designed fuses in a fuse box that allows an individual to see if one or more particular fuses within the fuse box are broken. The fuse has one of two different configurations, depending on whether the fuse is used in a system that is used in a polarized or non-polarized system. In each scenario, the fuse includes a number of diodes, one of which is a light emitting diode (LED) that will be lit up when the fuse is working and will not be lit up when the fuse is broken and/or not working.

 Patent #8,686,596

A fuse box system and method providing for visual and/or remote sensing of interrupted fusing elements is disclosed. The system incorporates LEDs and/or remote sensing apparatus to permit indication of a "blown" fuse and/or circuit protection breaker. This system may be configured for both polarized and/or non-polarized applications and generally provides for indicator illumination when a fuse/breaker is blown. Some preferred embodiments may incorporate current sourcing technologies to permit operation of the system over wide range of system voltages, as well as provisions for wired and/or RF/wireless interrogation of the fuse/breaker status. Alternate embodiments including systems/methods to permit remote sensing of fuse status and/or circuit current monitoring, and may be retrofit within existing fuse/breaker panel systems in some configurations.
