Standard of the month

AS/NZS 3001.2:2022 is the updated Part 2 of AS/NZS 3001, covering the safety requirements for connectable electrical installations. This edition supersedes AS/NZS 3001:2001 and is now formally cited in the Electricity (Safety) Amendment Regulations 2025, which came into force on 13 November 2025.

This revision introduces several important safety and compliance updates, particularly focused on modern battery systems, lithium technology, and installation practices in relocatable units.

Key Changes You Need to Know

1. Separation of Voltage Systems
Low voltage (LV) and extra-low voltage (ELV) systems must now be physically separated and isolated to reduce safety risks.

2. Battery Replacement and Upgrades
Batteries in connectable installations must be replaced only with the same type(s) originally installed.

Any upgrade must be performed by a competent person, following the requirements of AS/NZS 3001.2:2022 Section 5.

3. Lithium Battery Installation Requirements
Where lithium batteries are installed inside the interior of a connectable installation:

  • they must be housed in a sealed, externally vented enclosure
  • this protects occupants from corrosive effects and prevents gases from entering habitable spaces.

4. Battery Management and Certification
All lithium batteries must:

  • include a battery management safety system (integrated or separate)
  • be certified to comply with AS IEC 62619.

5. Battery Charger Requirements
Chargers connected to LV AC supply used for charging ELV batteries must:

  • have electronically regulated output voltage and current as per manufacturer specifications
  • provide output current of at least 10% of the battery capacity, ensuring adequate recharge capability.

6. Protection of Metallic Service Lines
Metallic service lines (gas, diesel, fuel, water) located within 300 mm of battery terminals must be insulated or dielectric-shielded to prevent accidental contact.

7. Inverters and RCD Protection
Inverters supplying the installation must:

  • comply with AS/NZS 4763
  • be protected by a dedicated Residual Current Device (RCD).

8. Damp Situation Installations
Electrical installations in damp areas of relocatable units must comply with both AS/NZS 3000 and AS/NZS 3001.2:2022.

9. Prohibited Locations
The standard introduces prohibited locations for LV and ELV switches and socket outlets to enhance safety.

Applicability

This standard applies to:

  • all new builds
  • all alterations, including upgrades to battery systems within connectable electrical installations.
