In order to mitigate a shock hazard for a user analyzing a high-voltage circuit, a system is provided that facilitates quarantining a shock-hazard high voltage within an electrical panel while providing a safe low voltage to a voltage detection indication device for visual inspection, the system comprising; a voltage conversion module (VCM) that receives input voltage from one or more monitored high voltage lines and reduces the received input voltage to below a predetermined voltage level that does not pose a shock hazard to a user; a voltage detection indication module that receives the reduced voltage and provides a visible voltage indication to the user; and a removable data transmission cable the connects the VCM to the voltage detection indication module.

An electrical safety monitoring device includes a first set of digital switches and a second set of digital switches for each of a plurality of line inputs, a first set of visual indicators, wherein each of the first set of visual indicators is electrically connected to one of the first set of digital switches and a second set of visual indicators, wherein each of the second set of visual indicators is electrically connected to one of the second set of digital switches.

According to various features described herein, a wireless connection device facilitates providing wireless transmission of detected voltages on monitored lines, and comprises: a communication connector via which the wireless communication device receives detected voltage information for one or more monitored lines; and one or more printed circuit boards (PCB)s comprising circuitry for processing the received detected voltage information; and a wireless transceiver that transmits the processed voltage information wirelessly for presentation and storage on a remote device.

In order to provide an environmentally secured voltage testing interface, an electrical enclosure box comprising a front panel is herein-described, into which is mounted a voltage indicator comprising a plurality of LED indicators that indicate a status of one or more circuits coupled thereto and monitored thereby.
