Dock Management System with GFCI Failure Indication

An electric shock detection system for use with a dock having a dock frame and a dock wiring system that is connected to a power source by a dock breaker, the dock being disposed in water, the electric shock detection system configured for use with a remote unit, comprising:

• (a) at least one electricity probe configured to detect an electric voltage between a ground and at least one of the dock frame or the water;
• (b) a shock hazard indicator disposed adjacent to the dock that generates a human-perceptible indication of a shock hazard when a shock warning signal is asserted;
• (c) a communication chipset in communication with the remote unit;
• and
• (d) a control unit disposed on the dock and responsive to the at least one electricity probe and in communication with the shock hazard indicator and the communication chipset, wherein the control unit includes a processor that is programmed to:
• (i) store a first voltage value received from the at least one electricity probe, the first voltage value being no greater than a voltage known to be safe and designated as a baseline safe voltage;
• (ii) receive a plurality of second voltage values from the at least one electricity probe;
• (iii) when at least two successive second voltage values of the plurality second voltage values exceeds the baseline safe voltage by a preset margin, then assert the shock warning signal, open the dock breaker and transmit a shock warning indication to the remote unit via the communication chipset;
• (iv) when at a voltage is sensed in the dock wiring system after the dock breaker has been opened, then transmit a faulty dock breaker warning indication to the remote unit via the communication chipset.
