Abstract: Method and device for determining the absence of voltage in electrical equipment. An installed device is electrically connected to a power source. The installed device has circuitry capable of detecting voltage, performing self-diagnostics, and testing for connectivity to the power source. In one embodiment, the device can also check to see if the voltage is at a deenergized level, recheck for continuity and repeat the self-diagnostics. In another embodiment, the installed device can be electrically connected to the line and load side of a disconnect and have circuitry configured to check the status of the disconnect. In another embodiment, the device can be configured to communicate with a portable reader in order to transfer information to the portable reader. In yet another embodiment, the device can be configured to interact with a controller that controls access to the panel in which the device is installed.

Abstract: A system for testing electrical continuity of a device to a source wherein there is at least one conductor connecting the device to the source can include a reference capacitive load, an oscillator, and a microprocessor. The oscillator is selectively connected to the reference capacitive load and each conductor connecting the device to the source such that the frequency output of the oscillator is a function of the selected capacitive load of the oscillator. Each conductor connecting the device to the source is connected to the oscillator such that when each one is selectively connected, the output of the oscillator is a function of that conductor's parasitic self-capacitance. The microprocessor can then compare the frequency of the signal generated when each conductor is connected to the oscillator with the frequency of the signal generated when the reference capacitive load is connected.
