How this is calculated
The tool checks whether Clause 2.5.5 of AS/NZS 3000:2018 asks for separation inside a switchboard. It also reads the access and exit figures of Clause 2.10.2.2 and the Appendix K examples.
- Scope. It compares the board rating with the Cl 2.5.5 threshold. At or above it, Cl 2.5.5 applies.
- Incoming conductors. Where Cl 2.5.5 applies, the incoming supply conductors are insulated or separated (Cl 2.5.5.1).
- Internal separation. The tool says if the Cl 2.5.5.2 route needs internal separation. It lists the forms that suit that route, from Paragraph K6.2 and Table K2.
- Access. From Cl 2.10.2.2 it gives the clearance from each face that needs access. It also gives the unimpeded space around the board. A domestic board has its own front clearance.
- Exits. A switchroom can pass the rating or length trigger. Then the tool gives the exit count and doorway size.
- Clearance example. It reads the Appendix K clearance for the impulse voltage you pick (Paragraphs K6.4 and K6.5).
| Step | Table or clause | What it decides |
|---|---|---|
| Scope and separation | AS/NZS 3000 Cl 2.5.5 | Whether the board needs separation |
| Forms | App K Para K6.2 and Table K2 | The forms that suit |
| Access and exits | Cl 2.10.2.2 | Clearances, exits and doorways |
| Clearances | App K Para K6.4 and K6.5 | The worked examples |
Worked example
A 1000 A commercial board in a switchroom. Cl 2.5.5 applies and internal separation is required. Forms 3b, 4a or 4b suit. The tool gives 2 exit paths, set well apart. The Appendix K clearance at 6 kV is 5.5 mm.
Limits
- Appendix K is informative. Its clearance and creepage figures are examples. Verify them to AS/NZS 61439.1.
- The tool holds the Cl 2.5.5.2 route only. Cl 2.5.5.1 offers other routes.
- Under the trigger, the tool gives no exit count and no doorway size.
- Measure each clearance with the doors and gear in the positions the clause names.
- Door swing and hold-open rules appear as warnings only.

Āhea me whai wehenga ō roto te papa hiko?
Ka whakaūru a AS/NZS 3000:2018 Clause 2.5.5 i tētahi papa hiko e 800 A te rahi, neke atu rānei ia wāhanga. Whakauru i te reiti, ā, ka kī a AmpSize mēnā e ea ana taua papa i taua tohu. Ka tono hoki a Clause 2.5.5.1 kia whakamaru, kia wehea rānei ngā kaikawe puna hiko e uru mai ana, i ia ara. Ka whakatakoto a Clause 2.5.5.2 i te wehenga o roto e hiahiatia ana e te papa.
Ko ēhea ngā form of separation e whakaaetia ana?
Ka whakaingoatia e Appendix K Paragraph K6.2 a Form 3b, Form 4a me Form 4b, me ngā momo ōrite me ngā āpiti i, h me ih. Ka whakaatu a Table K2 ko wai ngā wehenga o ia Form. He mōhiohio anake a Appendix K, nā reira me titiro ēnei he tauira huarahi ki a Clause 2.5.5.2, ehara i te uara i whakatakotoria e te paerewa.
He pēhea te wāhi e hiahiatia ana huri noa i tētahi papa hiko?
Ka whakatakoto a Clause 2.10.2.2.1 i te 1.0 m mai i ia kanohi e hiahia ana ki te uru. Ka taea e tētahi whakaurunga kāinga te whakamahi i te 0.6 m ki te kanohi o te papa. Ka whakamahi a AmpSize i tērā mahi whakaurutanga ki te kanohi mua. Ka pupuri ngā kanohi atu i te 1.0 m. Ka whakatakoto te clause i te mokowā 0.6 m kāore e ārai ana huri noa i te papa. Pānuitia te clause mō ngā tūnga tatau me te switchgear e whakaaro ana ia.
Āhea e hiahiatia ai ngā ara putanga ohotata e rua?
Ka whakatakoto a Clause 2.10.2.2.2 i ngā ara putanga e rua, he tawhiti te wehenga, ina me uru koe ki tētahi rūma kia tae ki te papa. Ka hāngai tēnei mai i te 800 A ia wāhanga, neke atu rānei i te 3 m te roa. Ka rite tētahi ara kotahi mēnā ka mau te 3 m kore ārai ki mua me ngā tatau kua tuwhera me ngā taputapu kua tōnoa. Me whai ngā papa atu he ara putanga e rite ana, kāore he tatau kua whakatauhia.
Ko tēhea putanga e pānuihia ana e te taputapu, ā, he aha ngā mea e waiho ana e ia?
Ka pānui te taputapu i AS/NZS 3000:2018 me ngā Amendment 1, 2 me 3. I whakahoungia e Amendment 2 a Clause 2.10.2.2. I tangohia anake e Amendment 3 ngā tohutoro AS/NZS 3439 i Clause 2.5.5. Kei te taputapu a Clauses 2.5.5 me 2.10.2.2, me ngā Paragraph K6.2, K6.4 me K6.5 o Appendix K. Ko ngā arotake rated diversity factor me te temperature rise kei te raupapa AS/NZS 61439, nō reira kāore te taputapu e pupuri ana i aua mea.
