Who this page is for
Engineers, reviewers and clients checking the qualifications and engineering judgement behind the ElecAS calculators.
What this tool helps with
- Standards-first: every calculator traces back to the relevant clause in AS/NZS 3000:2018 or AS/NZS 3008.1.1:2025.
- Practitioner-built: created by an engineer who runs the same calculations on real projects.
- Full credentials: B.Eng (Electrical), MIEAust, CPEng, NER, NSW DBP, NSW PRE, APEC, IntPE(Aus).
Wisam Tozah: the electrical engineer behind ElecAS
Who builds ElecAS
ElecAS is designed, built and reviewed by Wisam Tozah, a practising electrical engineer based in Sydney, Australia. Rather than a generic calculator wrapped around international defaults, ElecAS is a practitioner tool: the same maximum demand, cable sizing, voltage drop and earthing calculations it performs are the ones run day to day on real Australian electrical projects.
Credentials and registration
Wisam holds a Bachelor of Engineering (Electrical) and is a Member of Engineers Australia (MIEAust), a Chartered Professional Engineer (CPEng) and listed on the National Engineering Register (NER). He is registered as a NSW Design and Building Practitioner (DBP) and NSW Professional Registered Engineer (PRE), and holds APEC Engineer and International Professional Engineer (IntPE(Aus)) recognition.
These registrations sit behind the engineering judgement in ElecAS: every calculator is traced back to the relevant clause in AS/NZS 3000:2018 or AS/NZS 3008.1.1:2025 and reviewed before it reaches production.
Why a practising engineer built ElecAS
ElecAS started from the work itself: running the same standards calculations repeatedly across projects and wanting them faster, traceable and consistent. Building the suite as a practitioner means the calculators are shaped by how the standards are actually applied on site and in design submissions, not just by the letter of the formula. Each tool exposes the inputs, intermediate values and the clause or table it relied on, so a reviewer can re-trace the result by hand.
Engineering responsibility
ElecAS is a design aid for qualified electrical professionals, not a substitute for one. It confirms that the calculation method and its implementation are correct, but the user remains the engineer of record: responsible for selecting the right method, validating inputs and confirming results against current standards and project conditions before issue, construction, energisation or certification. The Verification page documents the testing and review process in detail.
Frequently asked questions
Who created ElecAS?
- ElecAS is created and maintained by Wisam Tozah, an Associate Electrical Engineer based in Sydney, Australia, holding B.Eng (Electrical), CPEng, NER, MIEAust, NSW DBP, NSW PRE, APEC and IntPE(Aus) credentials. He builds and reviews every calculator against the primary Australian Standards.
Are the ElecAS calculators reviewed by a qualified engineer?
- Yes. Every calculator is implemented from the relevant Australian Standard, validated against worked examples and reviewed by a Chartered Professional Engineer (CPEng) before release. The Verification page documents the testing and review process in detail.
