I have asked this question before with no response. Probably in the wrong forum. If anyone has successfully used the above device can they please help with clarification of the wiring diagram given in the product manual. As at present, it seems to suggest that a short circuit would occur joining neutral and live when the relay is actuated.Comparison with the circuitry for a similar apparatus obtained from the Internet, the Fridgemate shows a clear and unambiguous ,electrically safe system. Your assistance would be appreciated.
