ElecAS
Electrical Design Guides — Interactive AS/NZS & NCC Walkthroughs
A growing library of free, interactive electrical design guides for Australian and New Zealand engineers, electricians and designers. Each guide is a self-contained, step-by-step walkthrough of a real design task — the standard behind it, the method worked line by line, an interactive calculator to try your own numbers, a worked example and the compliance check. Current guides cover inverter and solar voltage rise to AS/NZS 4777.1, and emergency and exit lighting to AS/NZS 2293.1 and NCC 2022 Part E4. Every guide links straight to the matching ElecAS calculator for production design work and a branded PDF report.

This static content is published so the canonical route has meaningful crawlable HTML even before the interactive application hydrates.
Who this page is for
Australian and New Zealand electrical engineers, CEC accredited solar designers, licensed electricians, electrical designers and students learning the AS/NZS and NCC design framework.
Relevant standards
- AS/NZS 4777.1:2016 (Grid connection of energy systems via inverters — voltage rise)
- AS/NZS 2293.1:2018 (Emergency escape lighting and exit signs — design)
- NCC 2022 Volume One Part E4 (Emergency lighting, exit signs and warning systems)
- AS/NZS 3008.1.1:2025 (Selection of cables — conductor impedance)
What this tool helps with
- Interactive, step-by-step design guides — read the method, then try it live in an embedded calculator.
- Solar and inverter voltage rise to AS/NZS 4777.1 — the 2% limit, the formula worked line by line, and how to fix a failing design.
- Emergency and exit lighting to AS/NZS 2293.1 and NCC 2022 Part E4 — where it is required, luminaire classification and spacing.
- Each guide links to the matching ElecAS calculator for real project work and a branded PDF report.
- Written and reviewed by a Chartered Professional Engineer (CPEng, NER).
