Classes of RCDsRCDs are classified in AS/NZS 3190:2011 Approval and test specification – Residual current devices (current-operated earth-leakage devices). The two relevant types are:
Requirement for ‘appropriate’ RCDsThe WHS Regulations require ‘appropriate’ RCDs to be selected and used in the specified higher-risk operating conditions. If an RCD is required, the RCD must have a tripping current that does not exceed 30 milliamps if electricity is supplied to the equipment through a socket outlet not exceeding 20 amps. The WHS Regulations do not prescribe whether RCDs must be non-portable or portable. The most ‘appropriate’ RCD will depend on the workplace environment. To assist with proper selection, further information about the advantages and disadvantages of different kinds of non-portable and portable RCDs is described in Appendix B. You may need to seek technical advice from a competent person about the kinds of RCDs that are appropriate for your workplace. However, for construction and demolition sites you must comply with AS/NZS 3012:2010. Additional requirements for the installation of non-portable RCDs may also apply under local building and electrical safety laws as set out in AS/NZS 3000:2007 Electrical installations (known as the Australian/New Zealand Wiring Rules). Inspecting and testing RCDsRegulation 165 A person with management or control of a workplace must take all reasonable steps to ensure that residual current devices used at the workplace are tested regularly by a competent person to ensure the devices are working effectively. A record of testing (other than daily testing) must be kept until the device is next tested or disposed of. AS/NZS 3012:2010 applies in relation to construction and demolition sites. Persons with management or control of a workplace must take all reasonable steps to ensure that RCDs used at the workplace are tested regularly by a competent person. This requirement covers RCDs used in all operating environments including non-portable (or ‘fixed’) RCDs. If an RCD is tested and found to be faulty it must be taken out of service and replaced as soon as possible. Requirements for inspecting and testing electrical equipment used in certain higher-risk workplaces which could, for example include portable RCDs, are explained in Section of this Code. For guidance on approval and test specifications, see AS/NZS 3190: Approval and test specification – Residual current devices. Testing new portable RCDsA new portable RCD unit should be tested by pressing the ‘trip test’ button to ensure the RCD is effective.
