Key facts

  • The calculation engines are identical on every plan; paid tiers never change the results.

Who this page is for

Engineers, contractors and consultancies comparing free and paid electrical design tools for Australian standards work.

What this tool helps with

  • Free plan: every AS/NZS calculator with no sign-up to calculate, unlimited calculations, save to your device, and free PDF export with a free account.
  • Pro plan: cloud save and sync across devices, unlimited saved calculations, custom logo and accent colour on PDF reports, project workspaces and priority support.
  • AI Pro plan for designers who describe a job in plain English and get the calculation back.

What is free in ElecAS, and what Pro and AI Pro add

The free plan is the whole calculator suite

Every ElecAS calculator is free to use with no sign-up required to run a calculation: cable selection, voltage drop, voltage rise, maximum demand (Tables C1, C2 and C3), conduit and cable tray fill, earthing, derating, power factor correction, generator sizing, UPS battery sizing, LED inrush, arc flash and the rest of the suite, plus the EleCAD single line diagram builder. There is no calculation cap and no daily limit.

Exporting is free too: downloading the branded PDF report (or the DXF from EleCAD) requires only a free account. The free-tier PDF carries your name, company and accent colour with full standards citations.

What Pro adds

Pro is for practitioners who live in the tools: cloud save and sync across devices, unlimited saved calculations, project workspaces that group calculations by job, a custom logo on PDF reports and priority support. The calculators themselves are identical on every plan; Pro changes how your work is stored, branded and organised.

What AI Pro adds

AI Pro extends Pro with a much larger AI Mode allowance. AI Mode lets you describe a job in plain English (the run length, the load, the installation method), and get the calculation back, run by the same engines as the calculator pages and exported as the same PDF. Usage is metered in tokens, and every plan shows the remaining balance on the AI Mode page.

Frequently asked questions

Is ElecAS free to use?

Yes. Every ElecAS calculator (cable sizing, voltage drop, maximum demand, conduit and cable tray sizing, earthing, power factor correction, generator sizing, UPS battery sizing and more) is completely free, including PDF export. No account or sign-up is required to calculate.

What does ElecAS Pro add over the free plan?

Pro adds cloud save and sync across devices, unlimited saved calculations, removal of ElecAS branding from PDF reports, your own company logo and accent colour on reports, project workspaces with folders, and priority email support.

Do I need an account to use the calculators?

No. All calculators work without an account. An account is only needed if you want to save calculations to the cloud, sync between devices or apply custom branding to PDF reports.

Do the paid plans unlock better calculations?

No. The calculation engines, standards tables and results are identical on every plan. Pro and AI Pro add storage, branding and AI Mode (cloud sync, project workspaces, custom logo, a plain-English assistant), never accuracy or extra standards.

Is PDF export free?

Yes. The branded PDF report is free on every calculator; downloading it requires only a free account. Pro adds a custom logo on the report, and AI Pro adds a larger AI Mode allowance.

Can I use the free plan commercially?

Yes. The free calculators are used daily by engineers, contractors and electricians on real projects across Australia and New Zealand. Responsibility for verifying design outputs remains with the certifying engineer, as with any design tool.
