AS/NZS 3000 Wiring Rules — What Applies to Bathroom Mirrors
What AS/NZS 3000 Is and Why It Applies to Bathroom Mirrors
AS/NZS 3000:2018, the Australian/New Zealand Wiring Rules, is the foundational standard for all electrical installations in Australia and New Zealand. It is referenced directly in the electrical safety legislation of every state and territory, which means it carries the force of law. When a licensed electrician installs a hardwired LED bathroom mirror, AS/NZS 3000 governs every aspect of that installation: the zone the mirror occupies, the circuit protection required, the earthing of metal parts, the connection method, and the certification the electrician must issue on completion.
This page covers the specific provisions of AS/NZS 3000 that apply to LED bathroom mirrors in detail.

Zone Definitions Under AS/NZS 3000
AS/NZS 3000 divides bathroom spaces into zones based on proximity to water sources. Each zone has different requirements for the electrical equipment permitted within it and the ingress protection rating that equipment must carry. The zone system applies to all fixed electrical equipment, including LED mirrors.
Zone 0
Zone 0 is the interior of the bath, shower tray, or basin. Electrical equipment in Zone 0 must be rated to IP67 or higher and be specifically designed for Zone 0 use. LED mirrors are never installed in Zone 0. This zone is included for completeness because it defines the reference point from which Zones 1 and 2 are measured.
Zone 1
Zone 1 is defined as the area directly above the bath or shower tray, from floor level to a height of 2.25 metres (or the ceiling if lower), and extending horizontally to the rim of the bath or shower tray. Electrical equipment permitted in Zone 1 must have a minimum IP44 rating, must be rated for Zone 1 use (which imposes additional requirements beyond IP44), and the circuit must be RCD-protected. Voltage is limited to SELV (Safety Extra Low Voltage, typically 12V or 24V DC) for certain equipment classes.
Most LED bathroom mirrors are not installed in Zone 1 — their operating voltage (typically 230V mains via an integrated driver) would place them outside the permitted equipment classes for Zone 1. However, in open-plan wet areas, ensuite configurations, or hotel bathrooms where the mirror is adjacent to an open shower, the zone boundary may be closer than expected. The installing electrician must verify zone placement before installation, not after.
Zone 2
Zone 2 extends 600mm horizontally beyond the boundary of Zone 1 and from floor level to a height of 2.25 metres or the ceiling. Zone 2 is the zone where most wall-mounted LED mirrors are installed — above a vanity basin that is itself in Zone 1 (the basin being a water source), with the mirror positioned on the wall above and behind it. Equipment in Zone 2 must have a minimum IP44 rating. There is no voltage restriction for Zone 2, meaning mains-operated LED drivers are permitted, subject to standard safety requirements.
In practice, a mirror positioned directly above a freestanding vanity basin is almost always in Zone 2. The electrician confirms the exact zone by measuring from the rim of the basin horizontally and vertically. Our bathroom zones IP requirements guide provides a zone map description and measurement methodology.
Outside Zones
The area beyond 600mm horizontally from Zone 1, and above 2.25 metres, is considered outside the defined zones. Electrical equipment in this area is not subject to bathroom-specific IP requirements under AS/NZS 3000, though general electrical safety standards still apply. In large bathrooms — typically those found in luxury residential or hotel contexts — some mirrors may be positioned outside Zone 2, making IP44 technically unnecessary under the wiring rules alone. However, specifying IP44 regardless of zone position is best practice, as water vapour and condensation affect all bathroom environments.
RCD Protection Requirements in Zone 1
AS/NZS 3000 mandates that all socket-outlets and fixed equipment in Zone 1 are protected by a residual current device (RCD) with a rated tripping current not exceeding 30mA. RCDs provide protection against electric shock by detecting leakage current to earth and disconnecting the circuit within milliseconds. This requirement reflects the dramatically elevated risk of electric shock in environments where water and electricity can come into contact with the human body simultaneously.
For LED mirrors installed in Zone 2, RCD protection is not mandated by the zone definition alone — but it is mandated by other clauses of AS/NZS 3000 that require RCD protection for all socket-outlets in domestic premises and for certain fixed equipment. Since 2018, AS/NZS 3000 has progressively expanded RCD protection requirements, and many state electrical safety frameworks impose broader RCD requirements than the standard minimum. In Queensland, for example, RCD protection is required for all final sub-circuits in domestic and residential buildings. The installing electrician must be familiar with the current requirements in the relevant state. Our electrician requirements guide covers state-specific obligations.
Earthing of Metal Frames and Bodies
Clause 5.4 and related clauses of AS/NZS 3000 require that all exposed conductive parts of fixed electrical equipment — parts that can be touched and that could become live in the event of an insulation fault — must be connected to the protective earth conductor. For LED bathroom mirrors, this means the metal frame, metal body, or any other metallic component that is electrically connected or adjacent to live components must have a protective earth terminal and a connected earth conductor.
This is a common failure point with cheaper imported LED mirrors. Products manufactured without proper earthing terminals, or with earth terminals that are not connected through to the mirror frame, fail this requirement. An electrician who installs such a product is installing a non-compliant product and bears professional liability for that choice, even if the product was supplied by someone else.
VUELUXE mirrors are manufactured with earthed metal frames and proper earth terminals as a standard feature. The wiring diagram provided with each product includes the earth conductor connection point. Electricians should confirm earth continuity with a meter before sign-off on any LED mirror installation.
Isolation Distance from Zone 1
AS/NZS 3000 requires that switches, socket-outlets, and similar devices not be installed within Zone 1, and that any switch controlling equipment in Zone 1 be located outside that zone unless it is a pull-cord type designed for Zone 1 use. For mirrors, this means the mirror’s touch sensor controls and any integrated USB charging outlets must be considered in the zone analysis.
A mirror installed entirely within Zone 2 with its touch controls on the mirror face is compliant, provided the mirror itself carries IP44 or higher. If the mirror is positioned partly in Zone 1 (which is rare but possible in compact wet areas), a different approach is required: either relocating the mirror outside Zone 1 or specifying a mirror with SELV-rated controls and appropriate Zone 1 certification. In practice, the builder or designer should confirm zone placement during the layout design phase, before product selection, to avoid specification errors that require rectification after installation.
Plug-In vs Hardwired: What AS/NZS 3000 Requires
The most common misconception about LED mirror installation is that a plug-in (GPO-connected) mirror does not require a licensed electrician. This is incorrect in all material respects.
AS/NZS 3000 does not distinguish between hardwired and plug-in fixtures for the purposes of zone compliance, IP rating requirements, or earthing obligations. A plug-in LED mirror in Zone 2 must still carry IP44 minimum. The GPO it connects to must be installed by a licensed electrician. If the GPO is not already present in the correct location, a licensed electrician must install it — and that installation must comply with AS/NZS 3000, including RCD protection where required.
Furthermore, in many instances a plug-in mirror inside a bathroom is not appropriate. AS/NZS 3000 prohibits general-purpose socket-outlets (GPOs) in Zone 1 and Zone 2, with specific exceptions for shaver supply units that comply with AS/NZS 3111. A standard GPO installed within Zone 2 is non-compliant. If the mirror requires a mains plug connection, it must connect to a GPO positioned outside Zone 2 (more than 600mm from the basin rim), or to an approved shaver supply unit within Zone 2.
The practical outcome for most bathroom mirror installations is that hardwired connection is the standard approach. The electrician runs a dedicated circuit to the mirror’s connection point, connects the mirror’s flying lead or terminal block to the circuit, and certifies the installation. This is not more expensive or complicated than a GPO installation — it is simply the correct method. See our IP rating explained page for context on IP44 in Zone 2 installations.
What the Installing Electrician Must Certify
When an electrician completes a bathroom mirror installation, they must issue a compliance certificate to the owner or head contractor under the relevant state electrical safety framework. The exact form varies by state (Certificate of Electrical Safety in Victoria, Certificate of Compliance for Electrical Work in Queensland, Certificate of Compliance in NSW and SA — see our electrician requirements page for state-by-state detail), but the substance is consistent across all jurisdictions.
The certifying electrician is declaring that:
- The electrical installation complies with AS/NZS 3000 and all applicable state electrical safety regulations
- The installed equipment carries the required regulatory marks (RCM for electrical equipment)
- The installation is in the correct zone with the correct IP-rated equipment
- All metal parts are properly earthed
- Circuit protection (including RCD where required) is in place
- The installation has been tested and is safe for use
Electricians who certify installations using non-compliant products — mirrors without RCM marking, mirrors with insufficient IP ratings, mirrors without earth terminals — are issuing fraudulent compliance certificates. The professional and legal consequences include licence suspension, fines, and civil liability in the event of an incident.
Common Wiring Mistakes on LED Mirror Installations
Beyond zone and earthing compliance, AS/NZS 3000 contains specific requirements that are often overlooked on LED mirror installations:
Insufficient cable size
LED mirrors with demister pads, LED strips, and Bluetooth speakers can draw up to 80–100W. While this is well within the capacity of standard 1.5mm² flex, the circuit protection device must be sized appropriately, and the cable must not be routed through insulation in a way that reduces its current-carrying capacity below the mirror’s maximum draw. The product data sheet will specify maximum wattage and connection requirements.
No strain relief on flying lead
The connection point between the mirror’s flying lead and the in-wall circuit must include strain relief to prevent mechanical stress on the terminal connections. Without strain relief, vibration or accidental tension can loosen terminal screws over time, creating a fault condition. Many LED mirrors include an integrated connector; the electrician must ensure it is properly seated and secured.
Reverse polarity
LED drivers are generally tolerant of reverse polarity, but touch sensor systems in some mirrors are polarity-sensitive. Reversed active and neutral connections can result in the touch sensor failing to respond or responding erratically. The product wiring diagram should be followed precisely. If in doubt, the electrician should contact the supplier before completing the connection.
Inadequate mounting for wall cavity depth
While not strictly an electrical issue, the mounting arrangement affects wiring access. Surface-mounted mirrors require a cable exit point through the wall or from a surface conduit. Recessed mirrors require a wall cavity of the correct depth for the mirror frame. The electrician and builder must coordinate on rough-in requirements before wall lining — checking the mirror specification sheet before installation commences is essential.
What to Ask Your Electrician Before Installation
Builders and project managers can reduce installation problems by confirming the following with the installing electrician before the mirror arrives on site:
- What zone is the mirror in, based on the confirmed position relative to the basin or shower?
- Is there an existing circuit in the correct location, or does a new circuit rough-in need to be scheduled?
- Is RCD protection already in place on the circuit, or does it need to be added?
- Has the electrician reviewed the product’s wiring diagram and connection method?
- Is the product’s RCM mark and documentation available for review before installation?
- What compliance certificate will be issued on completion, and when?
VUELUXE provides a wiring diagram, connection instructions, and compliance documentation with every order. Trade account holders can request these documents in advance of delivery for electrician review.
Summary
AS/NZS 3000 is the governing standard for every aspect of a bathroom mirror’s electrical installation in Australia. It defines the zones, the IP requirements by zone, the RCD protection obligations, the earthing requirements, and the certification the electrician must issue. Both hardwired and plug-in mirrors are subject to these requirements — the connection method does not change the zone compliance obligations.
