RCD Tripping Current Measurements
This test measures the RCD tripping current as you apply a test current and
then gradually increase the current until the RCD trips. You can use the test
leads or mains test cord for this test.
Note
For RCD type B (.) or S-type B (. G) all three test leads
are required.
XW Warning
To prevent possible electrical shock, fire, or personal injury:
• Test the connection between the N-conductor and earth
before you start the test. A voltage between the N-conductor
and earth may influence the test.
• Leakage currents in the circuit that follow the residual
current protection device may influence measurements.
• The displayed fault voltage relates to the rated residual
current of the RCD.
• Potential fields of other earthing installations may influence
the measurement.
If the L and N terminals are reversed, the Tester will automatically swap them
internally and continue tests. If the Tester is configured for UK operation, tests
stop and you will need to determine why the L and N are swapped. This
condition is indicated by arrows above the terminal indicator symbol (b).
