What is an RCD?

An RCD, or Residual Current Device, is a protective device that limits the amount of current that can flow through in a fault condition to below the level that can seriously hurt the average person.

Why is RCD testing important?

RCDs must be tested by law to ensure they are in safe working order, so that in the event of a fault they are ready to save lives. Unserviced equipment can seize up or just go unnoticed for years. Many insurance companies or lease agreements require regular testing to be carried out to comply with the terms and agreements.

Why choose KRC Electrical?

Unlike some electricians, we test your RCDs completely to ensure they will trip within the correct amount of time and within the specified current levels. Plain push-button testing on the RCD doesn't ensure the safety of you, your family, staff or pets.

100% satisfaction guarantee — we work tirelessly to go above and beyond your requirements.

    Process

    How rcd testing works

    1. Agree scope

      What's on site, how it's used and where it lives — that sets the test method and interval.

    2. Inspect & test

      A trained, competent person inspects and tests every item with the right instrument.

    3. Tag & record

      Results recorded: who tested, when, the outcome and the next due date.

    4. Fix & remind

      Faults flagged and remedied, and the next test lined up before it falls due.

    FAQ

    RCD Testing: your questions

    Q01Isn't pressing the test button enough?

    No. Plain push-button testing on the RCD doesn't ensure the safety of you, your family, staff or pets. We test your RCDs completely, to make sure they trip within the correct amount of time and within the specified current levels.

    Q02How often do RCDs need testing in a WA workplace?

    The WHS (General) Regulations 2022 (r.165) require RCDs used at a workplace — including fixed RCDs — to be tested regularly by a competent person, with a record kept until the device is next tested or disposed of. WorkSafe WA leaves the frequency to the business, based on a risk assessment or a competent person's advice. AS/NZS 3760 sets indicative intervals by environment.

    Q03What does an RCD actually protect against?

    An RCD (residual current device) limits the current that can flow in a fault condition to below the level that can seriously hurt the average person. The standard 30 mA RCD operates within 300 milliseconds for a 30 mA imbalance — that's what our trip-time testing verifies.
