電力容量/分電錶/總開關要求?(SA)
electrical-capacity · 州別版02數字表
| 要求 | 數值 | 條文 | 適用情況 |
|---|---|---|---|
| 供電相數門檻(Table 1-1) | — | Section 1.16–1.17(esp. Table 1-1, clause 1.17.8) +1 條 | NSW SIR Table 1-1: ≤100A per phase → 1/2/3 phase; >100A per phase → 3 phases + neutral; motor >2kW → 3 phase |
| 入線/總掣容量 vs 最大需求 | — | Prescribed electrical installation work requiring inspection | NSW SIR: replace where current carrying capacity exceeded by maximum demand per AS/NZS 3000 |
| NSW 總掣 >100A 加碼條文 | — | —(未引條文) | NSW SIR clause 1.17.8 'Main switchboards rated above 100A' |
| VIC prescribed work 檢查 | — | —(未引條文) | ESV reg 249: COES + licensed electrical inspector before connection to supply |
03Inspector 實睇乜
- 按 AS/NZS 3000 計 maximum demand,對現有 consumers mains/總掣額定,唔夠就申請升級
- 大功率設備(焗爐、熱水、冷氣、灶頭)加埋會唔會過每相 100A
- 三相設備/2kW 以上馬達有冇三相到點
- switchboard 有冇版位裝新 breaker+安全距離
- NSW:總掣 >100A 有冇跟 1.17.8;VIC:prescribed 工序有冇 COES+inspector 簽
- 多租戶分電錶/sub-meters 由電力公司/installer 出紙確認
04做錯幾多錢 + 幾時要決定
做錯成本:升級 consumers mains/換總掣視乎距離+容量,常見五位數(A$,practice 估);distributor 接電申請要以月計排期,誤開業日成本更高。
幾時要決定:簽租約後第一步查容量+問 distributor 報價(升級申請排期以月計);電工落場前定案。
最常撞板:
- 冇計 maximum demand 就落單買設備,接電先發現入線唔夠
- 全電化商用廚房冇升三相
- switchboard 冇位加 breaker,臨門改圖趕工
- VIC prescribed 工程冇 COES,接唔到電,開業日延誤

06常見問題
兩份官方文件:(1) NSW《Service and Installation Rules》(June 2025 版,energy.nsw.gov.au,Ausgrid/Endeavour/Essential 通用;注意封面印住『SUPERSEDED – FOR REFERENCE ONLY』,下格要查有冇新版):Table 1-1——maximum demand 唔超過每相 100A 可用 1/2/3 相+中性線;超過每相 100A 要 3 相+中性線;2kW 以上馬達要 3 相;最大需求一律按 AS/NZS 3000 計。原句:『existing services, consumers mains and service equipment shall be replaced (by the customer) to comply with these Rules, where their current carrying capacity is exceeded by the maximum demand determined in accordance with AS/NZS 3000』。clause 1.17.8 另有『Main switchboards rated above 100A』專節。(2) VIC Energy Safe《Prescribed and non-prescribed work》:總掣相關部分、consumer's mains、main earthing 等屬 prescribed electrical installation work(Electrical Safety (General) Regulations 2019 reg 249),原句:『a Certificate of Electrical Safety for prescribed electrical installation work is required to be issued and the work inspected by a licensed electrical inspector before connection to electricity supply』。其他州各有對應 SIR,本格只核實 NSW+VIC,其餘下格補。數值跨兩份快照,requirement value 照 KB5-009 先例用 null、數字收喺 applies_when/quote。
電力容量/分電錶/總開關要求?
駁電前先按 AS/NZS 3000 計 maximum demand 對現有入線/總掣容量:每相需求大過 100A 就要三相,2kW 以上馬達要三相;現有載流量唔夠就要由客戶出錢換;NSW 總掣額定 100A 以上有加碼條文;VIC 總掣/入線級別工程屬 prescribed work——要出 COES+持牌 inspector 驗完先接得電。
呢條係法定要求定係行業做法?
有官方文件、條款號、快照同 sha256,數值喺原文 grep 得到。
做錯會點?要幾時決定?
升級 consumers mains/換總掣視乎距離+容量,常見五位數(A$,practice 估);distributor 接電申請要以月計排期,誤開業日成本更高。 時間點:簽租約後第一步查容量+問 distributor 報價(升級申請排期以月計);電工落場前定案。
