[QUOTE="SPECIAL LOCATION, post: 505508, member: 250"] Re the off-load test requirement.. You will know, or should know some electrical equipment can have some natural leakage.. So if you were testing an RCD connected to circuit with loads with say 6ma of natural leakage already on the circuits.. how to you think that may affect your results? You need to test & verify that the RCD itself is operating correctly.. which although 90%+ of the time may well be quite accurate using a socket.. IF.. there are any strange or unexpected results.. then you need to get back to just the RCD so you don't start chasing the wrong problem.. An RCD that trips at 15ma with no loads connected is oversensitive.. (Providing your meter is suitably calibrated and known to be accurate). [/QUOTE]
