An electric current sensor detecting current leak into water flowing out from a water heater has been constructed. The sensor is made of a copper electrode implanted in a PVC pipe. It is subjected to tests in which the voltage is varied at constant resistance and otherwise the resistance is varied at constant voltage. The variation of the AC voltage is conducted from 0 to 220 volt whereas that of the resistance is from 1 KW to 100 KW. The 1 KW resistance is meant to represent the resistance of human skin in wet condition and the 100 KW represents that of dry insulated skin. Analysis shows that unpainful shock sensation surges at 30 V, 5.16 mA, with 1 KW resistance. In  the current leak condition at 220 V, unpainful shock is sensed at body resistance of 42 KW with 4,99 mA current.
