DG Series Ground Fault Sensors keep machinery and their operators safe from accidental shocks. The one-piece, solid-core design allows for installation over wires feeding loads to about fifty amps. The output relay will change state at factory setpoint between 5 and 50 mA of DC current to earth. WebAny leakage current flowing in the green safety ground wire would be seen as a non-zero reading at position #2, and any leakage current from the load to earth would show a non-zero reading at positions #2 or #3. Since the green wire is included in the test at position #3, only the ground current is registered as leakage in that case. did reaganomics lead to a balanced budget
