2. Electrical safety testing - Wikipedia

   en.wikipedia.org/wiki/Electrical_safety_testing

   Earth continuity test: this test is to make sure the earthing system is properly connected Live testing Earth fault loop impedance testing: this test is to check that if a fault did occur, that the system meets requirements to cause a disconnection of the supply within the time limit specified by standards

3. Isolated ground - Wikipedia

   en.wikipedia.org/wiki/Isolated_ground

   An isolated ground (IG) (or Functional Earth (FE) in European literature) is a ground connection to a local earth electrode from equipment where the main supply uses a different earthing arrangement, one of the common earthing arrangements used with domestic mains supplies.

4. Ground continuity monitor - Wikipedia

   en.wikipedia.org/wiki/Ground_continuity_monitor

   A GCM or ground continuity monitor (also called a ground integrity monitor or ground continuity tester) is an electrical safety device that monitors the impedance to ground of a temporary electrical circuit and can provide indication (or protective trip) in the event impedance rises to an unsafe value. A GCM is either an external testing device ...

5. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   It is important to note this action occurs regardless of whether there is a connection to the physical ground (earth); the earth itself has no role in this fault-clearing process [4] since current must return to its source; however, the sources are very frequently connected to the physical ground (earth). [5] (see Kirchhoff's circuit laws). By ...

7. Earthing system - Wikipedia

   en.wikipedia.org/wiki/Earthing_system

   The "local" Earth/Ground electrode provides "system grounding" [13] at each building where it is installed. The "Grounded" current carrying conductor is the system "neutral". Australian and New Zealand standards use a modified protective multiple earthing (PME [ 14 ] ) system called multiple earthed neutral (MEN).
