Earth Leakage Testing: this is a test designed to check how much current is flowing in an earth wire whilst an appliance is running.
=== This is done by either running the appliance though an alterative wiring system which allows for the earth wire to be seperated from the other conductors allowing for a clip on ammeter to be used or if possible connect a multimeter set on milliamps in series with earth wire. ===



=== These are pictures of how the alternative wiring is to be done. The earth (green wire) is seperated and run through a multimeter set on milliamps giving a reading of 0 milliamps which is below the maximum value of 5milliamps. ===
