  • Page 42: Leakage Testing

    Leakage testing A.3.1 Differential earth leakage test (IDIFF). Also called protective conductor current Test voltage: 230 Vac 50 Hz " " 19.9 mA The differential earth leakage test determines whether any current is flowing to earth. Normally appliances should have no, or very little, earth leakage current. A Class 2 (double insulated appliance) could exhibit earth leakage through its mountings or by operator contact.

  • Page 43: Rcd Testing

    However some equipment can draw very high inrush currents when starting. This should be considered when setting pass limits. Also, when a highly inductive load is run, the PAT400 may see the load as a short circuit. Under these conditions the load (operational) test should be started and the appliance switched on shortly afterwards. True short circuits can blow the fuse in the PAT400.
