Abstract: A high voltage proximity warning system, precise, easy to use, easy to install, rugged and weatherproof, has a control panel which is located in the cab of an excavator, other heavy equipment or vehicle, such that it is readily accessible to the operator during equipment operation and is connected to one or more strategically located sensor antenna(s). The control panel is designed to be used with or without gloves, in a position where it is readily visible. It is electrically connected to the equipment's power source. At least one high voltage proximity sensor is mountable to the vehicle and is in wired or wireless communication with the control panel.
