How this is calculated
The tool gives the supply arrangement and the RCD protection for a construction or demolition site. It reads AS/NZS 3012:2019.
- Supply arrangement. You pick the source, such as a distributor main. The tool finds the supply clause, here Cl 2.1.1(a).
- Additional protection. It reads Cl 2.4.6.1 for the circuit type and the exceptions. It says whether RCD protection is required.
- Residual current. It gives the maximum rated residual current for that circuit.
- Test intervals. It reads Table 6 for the inspection and test interval of the equipment.
- RCD tests. Table 6 also gives the push-button test and the operating time test.
- Switchboard points. It points at Cl 2.3.4 for socket‑outlets and Cl 2.4.4 for the isolating switch marking.
Worked example
- Final subcircuit from a distributor main, portable equipment. RCD protection is required at 30 mA. The inspection and test interval is 3 months. The operating time test is also 3 months. The push-button test is daily while the RCD is in use.
Limits
The RCD must trip on every active conductor and the neutral. Where a board feeds two or more lighting circuits, spread them across the RCDs. New Zealand sites also complete a Record of Assessment in the Appendix G form. The tool does not size cable. It does not check the cord length.
The tool gives one supply arrangement at a time. Pick the arrangement that matches the board in front of you. Then read the clause the tool names. Test the RCD on the site, as the intervals say. Record the results with the date.

He aha te mahi a te taputapu Puna Hiko Wāhi Hanga?
Ka whakaatu te taputapu i ngā whakaritenga supply e whakaaetia ana i tētahi wāhi hanga, wāhi whakaheke rānei, i te RCD protection mō te ara iahiko, me ngā wā arotake me te whakamātautau mō ngā taputapu. Ka mahi ia i raro i AS/NZS 3012:2019.
He aha te RCD e hiahiatia ana e tētahi wāhi hanga?
Ka whakamaru a Clause 2.4.6.1 i ia rere final sub‑circuit mai i te papa hiko wāhi hanga me tētahi RCD 30 mA te nui rawa, ka whakakore i ia kaikawe ora me te neutral. E toru ngā whakahāngaitanga: ka raru pea te mahi mīkini, te puna SELV, PELV rānei, me tētahi transformer wehe haumaru.
He aha te auau o te whakamātau i ngā RCD wāhi?
Tōmua he RCD pūkaha, ka tīmata rānei te generator, te inverter e mau ana i tētahi, kātahi ka pāwhiri i tana pātene whakamātau i mua i te hono taputapu. Mahia tēnei ia rā ka whakamahia. Pāwhiritia te pātene whakamātau o tētahi RCD whakatū ia marama. Mahia te whakamātautau wā mahi ia 3 marama mō tētahi RCD pūkaha, ia 12 marama mō tētahi RCD whakatū.
Ko ēhea ngā puna hiko e whakaaetia ana i tētahi wāhi?
Ka whakaae a Clause 2.1.1 i te main a tētahi kaiwhakawhiti hiko, i tētahi papa hiko o te whakaurunga pūmau, i tētahi huanga whakaputa voltage iti e whakaaetia ana e te whakaurunga ki AS/NZS 3010, i tētahi inverter ki AS/NZS 4763. Koia AS/NZS 3012:2019; i te putanga 2010 i ingoa anō a AS 2790 mō te generator. Ko ngā momo wiriwiri motuhake ka tuku anake ki tētahi ara wehe.
Ka uru te taputapu ki te aukati insulation mō ngā kaiwelder?
Āe, engari mō ngā arc welder kua hangaia ki ngā generating set anake, ko tērā te whānui e hoatu ana e Clause 3.5.4 ki Table 7 o AS/NZS 3012:2019. Ko ētahi atu taputapu ka whai i AS/NZS 3760; ka uru te taputapu Test and Tag a AmpSize ki aua arotake.
