With the release of the new wiring rules AS/NZS 3000:2018 there are now additional RCD requirements that you need to be aware of during the June – December transition period.

In residential installations, all circuits will now be required to be protected by 30mA Residual Current Devices (RCD), this now includes hard wired devices such as hot water systems, ovens and air conditioning systems.

NHP have you covered with a complete range of Residual Current Circuit Breakers (RCBO) and RCD devices to suit these needs with the NHP MOD6 range offering:

  • 6kA fault level
  • 6A to 40A current ratings RCBOs
  • 40A to 63A current ratings RCCBs
  • 10mA & 30mA sensitives
  • 1P, 2P and 3P&N
  • Switched neutral and un-switched neutral options

Not only have requirements for residential installations changed but there are also changes for non-residential installations. Formerly, socket outlets and lighting up to 20A required RCD protection, however this has now increased up to final sub-circuits up to and including 32A protecting socket-outlets and lighting.  Direct connected handheld equipment and directly connected equipment that represent increased risk shall have RCD protection. All other final sub-circuits up to and including 32A should be considered to have RCD protection.

To ensure these requirements are met, NHP have complete range of RCBO and RCD devices with the NHP DIN-T offering:

  • 6kA and 10kA fault levels
  • 6A to 40A current ratings RCBOs
  • 40A to 125A current ratings RCCBs
  • 10mA, 30mA, 100mA & 300mA sensitives
  • 1P, 2P, 3P and 3P&N
  • Switched neutral and un-switched neutral options

For medical installations or medical equipment in the home, NHP have RCDs meeting the required Australian Standard AS/NZS 3003. These solutions are with 10mA devices with switched neutral in 1P width devices, saving half the space of a typical 10mA RCD.

Increased risk applications such as outdoor equipment, kindergartens, or bathrooms, NHP have a 10mA range of devices to offer that extra level of protection.

When choosing to have upstream RCD protection it is important that special selective RCDs are used. Selective RCDs prevent the upstream RCD accidentally operating which would normally cut power to many circuits instead of the intended individual circuit. NHP also offer these selective type RCDs, Type S.

These changes are improving safety at home and at work so why wait for them to be enforced and make the first step to a safer environment now with NHP.
