Abstract
In a method of warning of a hazardous electrical condition at a dock with wiring coupled to a voltage source via a dock breaker, an electric voltage between a ground and at least one of the dock frame or the water is detected. A plurality of voltage values of the electric voltage is stored. When at least two successive voltage values of the plurality voltage values exceeds a baseline safe voltage by a preset margin, then a shock warning signal is asserted, a dock breaker is opened and a shock warning indication is transmitted to a remote unit via a communication chipset. When at a voltage is sensed in the dock wiring system after the dock breaker has been opened, then a faulty dock breaker warning indication is transmitted to the remote unit via the communication chipset.
