RCBO Prohibition

The prohibition of non-compliant compact RCBOs has been extended until 30 June 2030.

Extension of the prohibition of RCBOs

Energy Safe Victoria has continued the prohibition of compact RCBOs. The extension to the prohibition commenced 2 July 2020 and expires 30 June 2030.

Energy Safe has imposed additional requirements on the supply of RCBOs in Victoria

Suppliers must undertake additional testing and verification to ensure their products still operate satisfactorily if there is a defect in the installation or if the product has been installed incorrectly.

The prohibition applies to all compact RCBOs even if they are integrated in other electrical equipment such as preassembled switchboards.

The prohibition does not apply to DIN mountable RCBOs that are

  • greater than 110mm in length and
  • have a short circuit breaking capacity of 10kA or greater.

The prohibition also does not apply to RCBOs fitted into Portable Residual Current Devices (PRDCs).

However, all RCBOs that are marked or marketed as being for household or residential use are covered by the prohibition regardless of their length or short circuit breaking capacity.

Energy Safe has additional testing and verification requirements before an RCBO is compliant. If an RCBO covered by the prohibition is not on the list, it cannot be supplied or installed after 2 July 2020.

See the current list of compliant RCBOs

Background

Energy Safe’s investigation into RCBOs was instigated by a fatality in August 2016 in which it was found that a commonly-used RCBO failed to operate.

Energy Safe has identified two situations where 240V can be present on the load side of an RCBO when it is in the open position:

  • The device is installed in the opposite orientation to the one indicated by the manufacturer
  • The RCBO is installed in the correct orientation, however there is a defect in the installation downstream from the device and there is 240V present on the load terminals when the device is in the ‘off’ position.

The prohibition addresses this issue by ensuring that only RCBOs that do not have this design issue may be supplied in Victoria.

RCBOs of similar construction (pictured), may only be supplied if listed here: Compliant RCBOs

Energy Safe advises that compliance with the additional testing and verification requirements and the consequent listing on this website does not give any indication of the quality of the product.

It is not to be taken as

It is critical that electricians installing RCBOs follow the manufacturer’s instructions and test all installed RCBOs before they are placed in-service.

The RCBOs should be tested twice (test button pressed, RCBO reset and then test button pushed a second time ensuring the RCBO operates after each test) before the new installation is completed and commissioned.

If a RCBO covered by the prohibition is not on the list, it cannot be supplied or installed.
