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.
