How this is calculated
The tool places a light, switch or socket‑outlet in a zone. It then reads the least IP rating and the RCD rule for that zone. It follows Section 6 of AS/NZS 3000:2018.
- Situation. You pick the fitting: a bath, a shower, a basin, a spa, a pool or a sauna. Each one has its own table of zones.
- Reference point. Each situation measures from its own point. A bath measures from the internal rim. A shower measures from the fixed plumbing connection or the rose.
- Zone limits. The tool lists Zone 1, Zone 2 and Zone 3 (Cl 6.2.2.1). Each has a distance out and a height up.
- Device position. You enter the horizontal distance and the height of the device. The tool finds the first zone that holds that point.
- IP rating. The zone sets the least IP rating (Cl 6.2.4). The tool compares your rating with it.
- RCD and position. The tool adds the RCD rule for a home (Cl 2.6.3.3.1). It also gives the lowest height for a socket‑outlet or switch.
| Step | Table or clause | What it decides |
|---|---|---|
| Zone limits | Cl 6.2.2.1 | The distance and height of each zone |
| IP rating | Cl 6.2.4 | The least IP rating for the zone |
| Walls and fixed barriers | Cl 6.2.1 | Where a zone stops |
| RCD | Cl 2.6.3.3.1 | The 30 mA rule for a home |
| Bonding | Cl 5.6.2.5 | The earth bond of conductive reinforcing |
Worked example
Each link opens the tool with its inputs.
- Luminaire at an open shower. The luminaire sits 0.3 m from the plumbing connection and 1.8 m up. It has an IPX2 rating. The tool puts it in Zone 1 and asks for IPX4 at least. The check fails on the IP rating.
Limits
- The tool does not model a barrier that shrinks a zone. Walls, doors, floors and ceilings also limit the zones. Check the room.
- A shower over a bath adds a radius from the shower connection. You must type that distance.
- Equipment behind a fixed IPX4 panel that needs a tool to open is not in a zone. The tool does not decide this for you.
- A recessed fitting with all live parts above the ceiling is outside the zones below it.
- Protection by obstacles or by placing out of reach is not allowed in these zones.
- The tool points at the clause. It is not a ruling on a design.

Pātai

Kia pēhea te teitei o te Zone 1 i NZ me te Ahitereiria?
Ko te Zone 1 i runga i te bath, i te shower e toro ana ki te 2.25 m i runga i te papa i Aotearoa, ki te 2.5 m i Ahitereiria. Ka piki ki te hononga shower ina teitei ake. Ka mutu te Zone 2 i te 2.25 m i ngā whenua e rua. Ko te Zone 3 Ahitereiria ka uru hoki ki te mokowā i runga i te Zone 2, tae atu ki te 2.5 m.
Ka taea te whakauru i tētahi socket‑outlet ki tētahi wharepaku?
Kāore e whakaaetia i te Zone 0, i te Zone 1 rānei. I te Zone 2, me he shaver supply unit, me noho rānei ki tētahi RCD 30 mA i roto i tētahi kāpata. I te Zone 3, me whai RCD 30 mA, ara iahiko wehe (separated circuit), SELV rānei. Kia 0.3 m te teitei, neke atu rānei, o ia socket‑outlet me ia switch i runga ake i te papa.
Me pēhea te reiti IP e hiahiatia ana e tētahi downlight kei runga i tētahi shower?
IPX4 in Zone 1 or Zone 2. A ceiling rose gives a Zone 1 of 1.2 m in NZ and 0.6 m in Australia, up to the rose height. A recessed light with all live parts above the ceiling sits outside the zone below it.
Ka kapi te IPX7 i tētahi zone e tono ana i te IPX5?
Kāo. Ko te tau tuarua tae atu ki te 6 e kapi ana i ngā tau iti atu, engari ko te 7, ko te 8 anake kāore e kapi ana i ngā rerenga wai (AS 60529 Cl 6). Ko te Zone 1 o te puna kaukau e tono ana i te IPX5, nō reira rapua tētahi tohu takirua pēnei i te IPX5/IPX7.
He aha te spa e rerekē ai i te 680 L me te 5000 L?
Ko tētahi spa tae atu ki te 680 L, ka whai i ngā zone bath me te shower. Mai i te 680 L ki te 5000 L, ka toro te Zone 1 i te 1.25 m mai i te ngutu, tae atu ki te 2.5 m. Ki runga ake i te 5000 L, ina honoa rānei ki tētahi puna kaukau, ka whai te spa i ngā zone puna kaukau.

- IP ratings for an outdoor point and a hosed shedWhich IP code an outdoor power point, a milking shed light and a hosed switchboard need, and why an IP67 light can fail where IP65 passes.
- Kitchen power points and the cooktop zonePlace power points and switches near a cooktop, an outdoor gas bottle and a gas vent. Check each distance to AS/NZS 3000 and hand the sink to the wet area tool.
- Wire a bathroom: zones, IP ratings and the RCDA New Zealand bathroom with a 1.6 m bath and an open shower, worked through the AS/NZS 3000 Section 6 zones, the IP each item needs, the RCD and bonding.

- IP ratings explained: each digit and letterWhat the two numerals of an IP code mean, what X, the letters A to D and H, M, S, W add, why IP67 is not better than IP65 for jets, and where 3000 sets a code.
- Power points near a cooktop, gas bottle and sinkThe AS/NZS 3000 zones that keep power points, switches and lights away from cooktops, gas cylinders, gas vents and regulators, and where sinks are checked.
- Damp situations: the Section 6 zonesHow AS/NZS 3000 Section 6 zones the space around baths, showers, basins, spas, pools, fountains and saunas, how to read an IP code, and what A2 changed.
