Full title and description

AS/NZS 3001.2:2022 — Electrical installations — Connectable electrical installations and supply arrangements, Part 2: Connectable electrical installations. Specifies requirements and guidance for electrical installations associated with connectable electrical installations intended for connection to external low-voltage a.c. supply systems (50 V a.c. to 1000 V a.c.) by detachable or fixed supply leads, and includes requirements for extra‑low voltage systems (below 50 V a.c. or 120 V d.c. ripple free).

Abstract

This standard sets out safety, installation and performance requirements for connectable electrical installations used in accommodation, habitation, residential, commercial and recreational applications (for example caravans, recreational vehicles, boats and similar connectable units). It covers protection and earthing arrangements, selection and installation of equipment, requirements for extra‑low voltage d.c. systems and batteries (including siting, ventilation, monitoring and battery management systems), and measures to prevent hazards such as electric shock, fire and physical injury.

Scope

AS/NZS 3001.2:2022 applies to connectable electrical installations intended to be connected to external low‑voltage AC supplies by detachable or fixed leads, and to associated extra‑low voltage supplies used within those installations. The standard addresses wiring, protective devices, earthing and bonding, protection against incorrect polarity, classification of internal and external zones (for example within vehicles and recreational craft), and specific requirements for batteries and battery systems used in connectable installations. It is intended for use where the installation is not covered by other more specific standards.

Key topics and requirements

• Requirements for connection arrangements to external low‑voltage a.c. supply systems (detachable supply leads and fixed leads).
• Protection, earthing, isolation and bonding rules suitable for connectable installations, including provisions for insulation monitoring devices where relevant.
• Classification of internal/external zones (e.g., wet areas, baths/showers) and selection/installation requirements for equipment in those zones.
• Detailed requirements for extra‑low voltage d.c. systems and batteries: battery type selection, capacity, terminals, installation, charging, ventilation, spill containment and proximity to other services.
• Mandatory provision for lithium‑ion battery management safety systems (BMS) and requirement that lithium batteries meet appropriate safety approvals (for example IEC 62619 where specified).
• Requirements for monitoring/display of battery state of charge and voltage for lithium battery installations.
• Protection against incorrect polarity and guidance on devices and sensors used to prevent reverse‑polarity/connection faults in connectable systems.
• Mechanical protection, conductor sizing, isolation of protective earthing conductors and requirements for structural metalwork and conductive materials.

Typical use and users

Typical users include electrical installers, caravan/RV and boat manufacturers, vehicle/equipment designers, certifying authorities and electrical safety regulators, maintenance technicians and competent electricians who install or inspect connectable electrical installations. The standard is used to design safe installation practices, to specify compliance requirements in procurement, and as a reference for regulators and test/inspection organisations.

Related standards

Commonly referenced and related standards include: AS/NZS 3000 (Wiring Rules), AS/NZS 3001.1:2022 (other part of AS/NZS 3001 series), the superseded AS/NZS 3001:2008, AS/NZS 3010, AS/NZS 3012 and various product/IEC standards referenced for batteries and safety (for example IEC/AS IEC 62619 for lithium batteries). The 3001 series replaces and reorganises content previously in AS/NZS 3001:2008.

FAQ

Q: What is this standard?

A: AS/NZS 3001.2:2022 is the Australian/New Zealand standard that specifies requirements for connectable electrical installations and their supply arrangements — Part 2: Connectable electrical installations. It sets installation, protection and battery requirements for units intended to be connected to external low‑voltage supplies.

Q: What does it cover?

A: It covers wiring and protective arrangements for connectable units, classification of internal and external zones, requirements for extra‑low voltage d.c. installations and batteries (including siting, ventilation, monitoring and BMS requirements), protection against incorrect polarity and other safeguards to minimise shock, fire and mechanical hazards.

Q: Who typically uses it?

A: Manufacturers and designers of caravans, RVs and boats; electrical contractors and certifying electricians; regulators and test/inspection bodies; and anyone responsible for installing or maintaining connectable electrical installations.

Q: Is it current or superseded?

A: Current. AS/NZS 3001.2:2022 is the active Part 2 edition published 18 November 2022 and it, together with AS/NZS 3001.1:2022, supersedes the older combined AS/NZS 3001:2008. Users should confirm if local regulations incorporate or modify clauses for regulatory compliance.

Q: Is it part of a series?

A: Yes — it is Part 2 of the AS/NZS 3001 series of standards (AS/NZS 3001.1 and AS/NZS 3001.2) which together replace the earlier AS/NZS 3001:2008. The series is intended to cover transportable structures, vehicles and connectable installations in a modular way.

Q: What are the key keywords?

A: Connectable installations, low‑voltage AC, extra‑low voltage DC, batteries, lithium‑ion, BMS, insulation monitoring, earthing, caravan, recreational vehicle, installation requirements (AS/NZS 3001.2:2022).
