About ElecAS: a practitioner-built Australian electrical design suite
What ElecAS is
ElecAS is a free suite of electrical design calculators built specifically for the Australian and New Zealand framework: AS/NZS 3000:2018 (the Wiring Rules) and AS/NZS 3008.1.1:2025 (cable selection). It covers the everyday design workflows: maximum demand (Tables C1, C2 and C3), cable selection and sizing, voltage drop and voltage rise, conduit and cable tray fill, earthing conductor sizing, current-carrying-capacity derating, power factor correction, UPS battery and generator sizing, and lighting design.
Every calculator runs in the browser with no sign-up to calculate and no paywall on the core calculation, and each result can be exported (with a free account) as a citation-rich PDF report that references the specific clause, table and formula behind the number: written to drop straight into a design submission or verification package.
Why ElecAS exists
Most general-purpose electrical calculators are built around international defaults and leave the engineer to reconcile them with the local standard by hand. ElecAS takes the opposite approach: it encodes the actual AS/NZS tables, formulae and worked examples directly, so the method on screen is the method in the standard. The goal is to make standards-correct Australian electrical design faster to produce and easier to check, without sacrificing traceability.
Standards-first by design
Each calculator is implemented from the primary standard rather than a second-hand summary, with the calculation logic separated from the interface as a pure, deterministic engine. Cable selection works against the current-rating, AC-resistance, reactance and grouping tables of AS/NZS 3008.1.1:2025; maximum demand follows AS/NZS 3000:2018 Appendix C; voltage rise references AS/NZS 4777 where inverter logic applies. The same engine that produces the on-screen value produces the value in the exported PDF, so there is no display-only rounding hidden between the two.
The calculation engines are covered by automated tests that run against the real checked-in standard reference tables on every change, and the methodology is documented in full on the Verification page.
Who builds ElecAS
ElecAS is designed, built and reviewed by Wisam Tozah, a practising electrical engineer based in Sydney, Australia: B.Eng (Electrical), MIEAust, CPEng, NER, NSW DBP, NSW PRE, APEC Engineer and IntPE(Aus). It is a practitioner tool: the same calculations it performs are the ones run on real Australian projects, and every calculator is reviewed against the source standard before release.
Frequently asked questions
Who is behind ElecAS?
- ElecAS is designed, built and reviewed by Wisam Tozah, a Chartered Professional Engineer (B.Eng Electrical, MIEAust, CPEng, NER, NSW DBP, NSW PRE, APEC Engineer, IntPE Aus) practising in Sydney, Australia. The full professional profile is on the creator page at elecas.com.au/creator.
Is ElecAS affiliated with Standards Australia or a cable manufacturer?
- No. ElecAS is an independent, practitioner-built tool. It implements the published methods of the AS/NZS standards and ships real Prysmian and Olex catalogue cable data, but it is not endorsed by Standards Australia, Prysmian or any other manufacturer.
How is calculation accuracy verified?
- Every calculation engine is a pure, deterministic module covered by automated tests that run against the real checked-in standard reference tables on every change, and the methodology is documented in full on the verification page. Each PDF report cites the clause, table and formula behind the number so the result can be independently checked.
Does ElecAS replace a certifying engineer?
- No. ElecAS is a documented design aid: it produces standards-cited calculations and reports, but final verification of design outputs remains the responsibility of the certifying engineer for each project, as required under the AS/NZS framework.
