Class 1 & 2 Leakage / Run Test
Disclaimer: blue power lead is required for this operation.
The Leakage Test is an alternate method to perform insulation resistance tests. Leakage testing is a major
function of the TNT - Series
Please Note: A Visual Inspection test must be carried out before any others (refer to First Test Section)
This test determines errors of leakage not otherwise detected in a normal insulation test. If there are any doubts
with insulation testing of the equipment, the Standard (AS/NZS 3760 since 2001) allows for a leakage test to be
carried out instead. The TNT - Series appliance testers have been designed to perform these tests. The Leakage
Test applies power to the Device Under Test and measures any imbalance or leakage current. The leakage is
tested to the limits of the class types specified in the Standard AS/NZS 3760 i.e. Class 1 = > 5mA as
2 = > 1mA as fail.
The Limit of imbalance measured on the TnT-RCD, + appliance tester will read well in excess of the limits set in
mA. However, should the supply circuit be protected by an RCD this device will trip anywhere between 10 to 30mA
and trip the mains supply switch OFF.
Procedure:
1.
Complete a Visual Inspection. For details refer to the First Test section. If the device passed the
Visual Inspection, continue with the following instructions, if not, refer to the First Test section.
