    • Find your RCD.

    • If you have RCD outlets you'll have to look for outlets with two buttons on them.

    • If your RCD is installed in your breaker panel you'll have to look for a larger breaker with a test button on it.

    • Press the test button.

    • The test button is usually coloured. If it is not, it is usually the only button or labelled "T" or "Test".

    • Contact an electrician to replace your RCD, if this did not cause your RCD to trigger!

    • To turn your power back on, you'll need to flip the lever back up, or press the reset button.

    • The reset button is usually the only other button on the device or is labelled "Reset".

    • Use a Duspol or a single-pole phase tester to find your phase conductor.

    • Tip: To increase visibility of the phase tester's indicator, touch PE or a grounded object with your hand. This should cause the tester's indicator to shine brighter or become more noticeable.

  4. How to test a GFCI/RCD, Apply a load between L and PE: passo 4, imagem 1 %32
    • Use the load feature of the Duspol to apply a load between L and PE.

    • This will not trigger an RCD with a rated residual current higher than 30 mA, though you shouldn't have an RCD rated over 30 mA installed in your home, as that's the maximum permissible rated residual current for personal protection anyways.

    • If your Duspol does not have the load feature or if you do not have a Duspol, you can still test the GFCI by shorting the neutral to ground. However, to do this, it is important to ensure that a device is currently drawing power from the circuit being tested. This is typically the case in most household settings.
