Externally mountable fault indicator assemblies for electrical devices, systems incorporating same, and methods of using same

A fault-indicator assembly for an electrical device that includes a housing defining an interior space that contains electrical components, wherein the housing includes an orifice in fluid communication with the interior space, and a fault within the electrical components causes a pressure rise within the interior space, the fault-indicator assembly comprising:

• a communication module designed and configured to communicate a fault-notification signal over one or more networks;
• a pressure-activated actuator that, when the fault-indicator assembly is deployed on the electrical device, is located outside of the interior space of the electrical device and is responsive to changes in pressure within the interior space of the electrical device;
• a communication trigger operatively coupled between the pressure-activated actuator and the communication module, wherein the communication trigger is responsive to an increase in pressure within the interior space of the electrical device via the pressure-activated actuator such that, when the pressure within the interior space of the electrical device reaches a preset pressure, the communication trigger triggers the communication module to send the fault-notification signal over the one or more networks;
• and
• a connecting structure configured to locate the fault-indicator assembly, including the pressure-activated actuator, exteriorly to the housing of the electrical device, the connecting structure having a fluid passageway that, when the fault-indicator assembly is deployed on the electronic device, fluidly couples the pressure-activated actuator to the interior space of the electrical device via the orifice.
