Protection earth connection detector

Abstract

A device for detecting and/or monitoring a protective earth connection in a mains electricity outlet includes an electrical current conducting unit between the line wire and/or neutral wire of the mains electricity and the protective earth wire allowing the flow of a detection current between the line wire and/or neutral wire and the protective earth wire. The device is furthermore configured for measuring the detection current and comparing the detection current with a preselected reference current. A method for detecting and/or monitoring a protective earth connection in a mains electricity outlet includes the steps of measuring a detection current from the line wire and/or neutral wire of the mains electricity through an electrical current conducting unit to the protective earth wire, and comparing the measured detection current to a preselected reference current.
