Tungkol sa calculator na ito
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.

Mga tanong
Design aid ang resulta. I-verify ito laban sa kasalukuyang standard.
Gaano kataas ang Zone 1 sa NZ at sa Australia?
Ang Zone 1 sa ibabaw ng bath o shower ay umaabot ng 2.25 m mula sa sahig sa New Zealand at 2.5 m sa Australia. Tumataas ito hanggang sa shower connection kapag mas mataas iyon. Humihinto ang Zone 2 sa 2.25 m sa parehong bansa. Sakop din ng Australian Zone 3 ang espasyo sa ibabaw ng Zone 2, hanggang 2.5 m.
Puwede bang ilagay ang socket‑outlet sa banyo?
Hindi ito puwede sa Zone 0 o Zone 1. Sa Zone 2, dapat itong shaver supply unit, o nakakabit sa 30 mA RCD sa loob ng cupboard. Sa Zone 3, kailangan nito ng 30 mA RCD, separated circuit o SELV. Panatilihin ang bawat socket‑outlet at switch na 0.3 m o higit pa mula sa sahig.
Anong IP rating ang kailangan ng downlight sa ibabaw ng shower?
IPX4 sa Zone 1 o Zone 2. Ang ceiling rose ay nagbibigay ng Zone 1 na 1.2 m sa NZ at 0.6 m sa Australia, hanggang sa taas ng rose. Ang recessed light na may lahat ng live parts sa ibabaw ng kisame ay nasa labas ng zone sa ibaba nito.
Sakop ba ng IPX7 ang zone na humihingi ng IPX5?
Hindi. Ang ikalawang numeral na hanggang 6 ay sumasaklaw sa lahat ng mas mababa, pero ang 7 o 8 lamang ay hindi sumasaklaw sa water jets (AS 60529 Cl 6). Ang pool Zone 1 ay humihingi ng IPX5, kaya hanapin ang dual code gaya ng IPX5/IPX7.
Bakit nagbabago ang spa sa 680 L at 5000 L?
Ang spa hanggang 680 L ay sumusunod sa bath at shower zones. Mula 680 L hanggang 5000 L, umaabot ang Zone 1 ng 1.25 m mula sa gilid, hanggang 2.5 m. Kapag higit sa 5000 L, o kapag konektado sa pool, sumusunod ang spa sa pool zones.

- 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.
Background
- 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.
