    Wiring Rules
  • About Us
The new 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 3 circuits per RCCB, a minimum of 2 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.

Easy no think solution

  • RCBOs used to protect stove, hot water and air conditioning instead of MCBs without RCD protection

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.
