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 and no paywall on the core calculation, and each result can be exported 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.
