Tungkol sa calculator na ito
How this is calculated
The tool checks whether two kinds of circuit may share a wiring system. It reads AS/NZS 3000:2018 Cl 3.9.8. It also gives the separation to keep from other circuits.
- Circuits. You pick the two circuit types, such as low voltage and extra-low voltage. The tool reads the rule for that pair from Cl 3.9.8.3.
- Wiring system. You pick the enclosure, such as a common enclosure or separate ones. The tool reads Cl 3.9.8.2.1 for the sharing of one system.
- Arrangement. You pick the arrangement in force. The tool checks it against the arrangements the clause permits.
- Result. The tool gives Yes or No, with the clause and the reason. It adds the separation to keep from a service or from data circuits nearby.
| Step | Table or clause | What it decides |
|---|---|---|
| Circuit pair | AS/NZS 3000:2018 Cl 3.9.8.3 | Whether the pair may share |
| Wiring system | Cl 3.9.8.2.1 | The enclosure the pair shares |
| Arrangement | Cl 3.9.8.3 | Which permitted arrangement applies |
Worked example
- Low voltage and extra-low voltage in one enclosure. The circuits sit in the same installation and occupancy, with no special arrangement. The tool answers No. They may share a wiring system only under one of three listed arrangements. The clause is Cl 3.9.8.3.
Limits
The tool reads the rules of Cl 3.9.8. It does not read the rules of a cable maker or a data standard. For telecommunications cable, check the cable own rules.
It does not size the separation by calculation. It states the rule. It does not cover induced noise or electromagnetic interference. Check the installation against the full clause before you rely on a Yes.

Mga tanong
Design aid ang resulta. I-verify ito laban sa kasalukuyang standard.
Ano ang ginagawa ng segregation tool?
Iniuulat ng tool kung puwedeng magbahagi ng pipe, conduit, cable, enclosure o tray ang dalawang circuit. Ibinibigay nito ang clause, ang arrangement na kailangan para sa mixed voltage, at ang minimum separation distance. Iniuulat din nito ang separation mula sa gas, tubig at telecommunications services.
Saang clause galing ang resulta?
AS/NZS 3000:2018 Clause 3.9.8. Sakop ng Clause 3.9.8.2.1 ang common pipe o cable, sakop ng Clause 3.9.8.2.2 ang segregation sa common enclosure, sakop ng Clause 3.9.8.3 ang voltage levels, at sakop ng Clause 3.9.8.4 ang gas, tubig at telecommunications services.
Ano ang minimum distance para sa segregation?
Nagbibigay ang Clause 3.9.8.2.2 ng 50 mm kapag distansya lang ang naghihiwalay sa mga circuit sa common enclosure. Ang ibang dalawang paraan ay cable na may sariling sheath at fire-resisting barrier. Hindi nalalapat ang rule sa switchboard kung saan nagsisimula o nagtatapos ang mga circuit.
Puwede bang magsama sa iisang wiring system ang low voltage cable at extra-low voltage cable?
Pinapayagan lang sa ilalim ng isa sa tatlong arrangement ng Clause 3.9.8.3. Sa una, ang low voltage cable ay nagbibigay ng proteksyon na katumbas ng double insulation. Sa ikalawa, ang bawat cable at bawat core dito ay may insulation na rated para sa pinakamataas na voltage sa run. Sa ikatlo, ang fixed continuous barriers ang nagbibigay sa low voltage cable ng sarili nitong compartment. Hindi kailanman puwedeng isama ang high voltage.
Nagbibigay ba ang tool ng separation distances para sa telecommunications?
Oo, yaong ipinapakita ng Clause 3.9.8.4(c) sa Figures 3.8 at 3.9. Sa ibabaw, o sa loob ng pader, sahig o kisame, panatilihin ang 50 mm o maglagay ng barrier. Sa shared trench sa New Zealand, panatilihin ang 50 mm sa pagitan ng mga conduit. Nasa AS/CA S009 at sa NZ TCF Premises Wiring Guidelines ang iba pang kaso. Wala sa hawak ng AmpSize ang alinman sa dalawang dokumento.
