RCD Replacement or Upgrade Method of Procedure
by David Sharp, from the Community
This method of procedure guides electricians through replacing or upgrading RCDs and RCBOs in NBN node cabinets, including CommScope and Nokia variants. It details HSE and SWMS requirements, confirming backup supply, isolating power, installing approved RCBOs, and performing tests per AS/NZS 3000 and 3017. The process covers documentation such as Certificates of Electrical Safety, updating single line diagrams, and submitting artefacts like photographs and readings. Technicians record start-up and running currents, voltages, and site observations to ensure compliance and service continuity.
