How this is calculated
The tool compares your measured test values with the limits for the circuit. Tick the tests you did. The tool checks only those.
- Insulation resistance. The tool reads the minimum and the test voltage from AS/NZS 3000 Cl 8.3.6. It also reads the AS/NZS 3017:2022 figure from Cl 4.5.4.
- Earth continuity. It reads the limit for the earth conductor size from Table 8.2. It also reads the limit at 80 % of the rated current. AS/NZS 3017:2022 Cl 4.4.4 gives the main earth and bonding limit.
- Loop impedance. It reads the maximum Zs for the device and disconnection time from Table 8.1.
- RCD trip time. It compares your measured time with the limit for the rated residual current.
- Polarity. You confirm polarity and connections. The tool does not measure them. It points at AS/NZS 3017:2022 Cl 4.6.4.
- Verdict. The result passes only when every test you ticked passes.
Worked example
- Lighting circuit, 2.5 mm² on a 20 A B curve breaker. Insulation is 50 MΩ against a 1 MΩ minimum. Earth continuity is 0.3 Ω against a 0.9 Ω maximum. Zs is 1.2 Ω against a 2.9 Ω maximum. The verification passes.
Limits
The tool does not take your readings. It does not correct a loop reading for temperature. A pass here is not a certificate. A competent person signs the verification. Use the loop impedance calculator to predict Zs before the test.

Mga tanong
Design aid ang resulta. I-verify ito laban sa kasalukuyang standard.
Ano ang ginagawa ng Test Results tool?
Ikinukumpara ng tool ang mga value na sinukat mo sa site sa acceptance limit ng AS/NZS 3000 Section 8. Sinusuri nito ang insulation resistance, earth continuity, loop impedance at RCD trip time. Ang bawat check ay nagbibigay ng pass o fail. Ang pangkalahatang verdict ay pass, fail, o not verified.
Ano ang minimum insulation resistance?
Ang Clause 8.3.6.3 ay nagbibigay ng 1 megohm sa 500 V direct. Ang sheathed heating element ay 0.01 megohm, at ang RCD functional earth connection ay 0.05 megohm. Kapag may surge protective o electronic equipment, puwedeng ibaba ang test voltage sa 250 V.
Aling loop impedance limit ang ginagamit nito?
Ang nakalistang maximum Zs mula sa AS/NZS 3000:2018 Table 8.1 para sa uri ng device, rating at disconnection time. Iniuulat din ng tool ang maximum Rphe at Re ng Table 8.2 sa 80 porsyento ng rated current, na kapaki-pakinabang sa pagsubok na walang load.
Bakit sinasabi ng tool na Not verified?
Hindi nagawa ang test na hiniling mo. Walang row sa Table 8.1 para sa device rating, o walang test na napili. Hindi nag-uulat ang tool ng pass sa check na hindi nito nagawa. Baguhin ang rating, o gamitin ang loop impedance tool.
Saan pumapasok ang AS/NZS 3017:2022?
Ibinibigay ng AS/NZS 3017:2022 ang mga paraan para sa bawat verification test. Tugma ang insulation at main earth limits nito sa Section 8, kaya binabanggit ng tool ang dalawa. Nire-round sa isang decimal ang loop impedance table nito, kaya ginagamit ng tool ang Table 8.1 para sa Zs.

Background
- The order of verification testsWhy AS/NZS 3017 tests earth continuity before insulation and loop impedance before RCDs, which circuits take which test, and where each limit comes from.
- Testing to Section 8: what each test provesThe Section 8 test sequence, what each test shows, and how a calculated earth fault loop impedance compares with the value a tester reads on site.
