New Australian Residential
Installations

2.6.3.2.2

Installation requirements

Australia only

RDCs shall be installed at the switchboard at which the final subcircuit originates.

2.6.3.2.2

Domestic & Residential installations

Australia only

30mA RCDs shall be provided for all final subcircuits.


AS/NZS 3000:2018 wiring rules require ALL final sub-circuits to be 30mA RCD protected.

This includes fixed electrical equipment like cooktops, hot water systems and air conditioning units.


- The requirements for a maximum of three circuits per RCCB, a minimum of two RCCBs and sharing of lighting circuits remain.

- It is recommended that each final sub-circuit is protected by a separate RCBO to avoid loss of supply to multiple circuits.



What changes do I need
to make to comply?

Safe and simple

RCBOs used to protect stove, hot water and air conditioning instead of MCBs only.

 

Single phase

Three phase



Best Solution

 

  • All sub-circuits protected by RCBOs
  • Fast installation - all devices on one busbar
  • Smallest footprint using single module RCBOs
  • Individual sub-circuit protection - no risk of loss of supply to multiple sub-circuits.
