How this is calculated
The tool checks the RCD protection of show, carnival and fair ground wiring. It reads AS/NZS 3002:2021 and the Electricity (Safety) Regulations 2010.
- Method of supply. You pick how the event wiring is supplied. The tool reads Cl 3.2.1 for that method.
- Rated residual current. It reads the maximum from Cl 3.2.1.2 and compares your device with it.
- Final subcircuit rating. It says whether the clause caps the rating of the subcircuit it applies to.
- Device and conductors. It names the device the clause calls for, and the conductors it must operate in.
- Enclosures. It gives the lowest IP rating for an HRC fuse base (Cl 2.4.2.1) and a connection facility (Cl 2.7.6.2).
- Interval. It gives the reg 75(1) assessment interval for a carnival or fair ground.
Worked example
- Event wiring from a connection facility, 20 A socket‑outlets, 30 mA RCD. The maximum rated residual current is 30 mA, so the device passes. The clause sets no cap on the subcircuit rating. The assessment interval is 1 year maximum.
Limits
The tool compares the rated residual current only. It does not check the device type or the number of poles. It does not decide whether an exception applies. The depth and height checks cover installation wiring only. AmpSize holds pages 1 to 21 of the standard. It does not hold Section 4, or Appendices C and D.
The tool suits a check of event wiring before it connects. It compares the rating you enter with the clause. It does not replace the check by a competent person that Cl 3.2.1.1 describes. Record where the overcurrent and RCD devices sit, so supply can return fast after a trip.

He aha te mahi a te taputapu show me te carnival?
Ka whakaatu te taputapu i ngā tauāhua RCD e whakaritea ana e AS/NZS 3002:2021 mō te waea whakaurunga me te waea huihuinga. Mō te waea whakaurunga, ka arotake anō ia i te hōhonu trench ina hiahiatia ngā pega roa, me te teitei aerial. Ka whakarārangi i ngā IP ratings mō te tūāpapa HRC fuse me te enclosure o te wāhi hononga. I Aotearoa, ka whakaatu i te wā regulation 75.
He aha te RCD e hiahiatia ana e tētahi carnival, huihuinga rānei?
Ko te Clause 2.5.1 mō ngā waea whakaurunga. Ka tono ia i te RCD 30 mA ki ngā final subcircuit tae atu ki te 32 A: ngā ara iahiko ki ngā socket‑outlet, ki ngā rama, ki ngā taputapu hono tōtika rānei he nui ake te tūraru hiko. Ka tono te Clause 3.2.1.2 i te RCD 30 mA ki ngā waea katoa o ngā huihuinga, ahakoa te reiti. Ko te taputapu he Type A, he pai ake rānei, ā, ka tapahi i ia active me te neutral.
He hōhonu pēhea me whai tētahi taura i raro i te whenua i tētahi wāhi show?
Mō ngā waea whakaurunga, e tono ana a Clause 2.7.4 kia 1.0 m neke atu ina tino tatari ngā pēke roa. Ko te roa he pēke, he kōwae taunga ki runga ake i te 400 mm. Me whakamaru tōtika anō te awaawa kaingā, ā, ka rārangi te taputapu i aua tikanga e whā ngā wā katoa. He clause tōna mō ngā waea huihuinga, kāore a AmpSize e pupuri ana.
He aha te kore e hoatu ai e te taputapu ngā tawhā kaikawe aerial?
Ina ngā pou o Table 3.1 i Clause 2.7.5.4.3 i tā a AmpSize, kei waho i te rārangi. Nō reira kāore e taea e AmpSize te whakatauritea te momo kaikawe me te rahi ki tētahi tawhā. He tūtohi haumaru ora tēnei, nō reira kua waiho atu e AmpSize. Pānuihia te tawhā i te paerewa.
He aha te auau o te aromatawai i tētahi whakaurunga carnival?
I Aotearoa, ka whakaae te reg 75(1)(d) kia kaua e neke atu i te 1 tau i waenga i ngā aromatawai ki AS/NZS 3002. Kei a AmpSize ngā whārangi 1 ki te 21 o taua paerewa. Nō reira kāore e uru ana ki te tikanga i Section 4 me Appendices C me D. Ka whakatakoto a Ahitereiria i tōna wā i roto i tētahi clause kāore a AmpSize e pupuri ana.
