Online electrical schema software: build a readable, exportable plan

An online electrical schema should clearly represent every device in a home, without forcing you into a heavy CAD tool. The goal is to start from the real floor plan, drop electrical symbols on it and send a PDF that anyone can read.

What is an electrical schema tool for?

An electrical schema tool helps you visualise power points, light points, switches, dedicated circuits, data points and safety equipment in a home.

For a house or unit, the main need is rarely an industrial schematic. What you want is a readable electrical plan on a PDF, useful for the quote, conversations with the electrician and on-site follow-up.

  • Locate equipment precisely on the floor plan.
  • Identify rooms and intended uses.
  • Prepare an automatic legend.
  • Export a shareable PDF.

Electrical schema, electrical plan and wiring plan: what is the difference?

The electrical plan shows where equipment sits in the home. The electrical schema explains how controls, circuits and connections are organised. The wiring plan focuses more on how elements connect to each other.

Planelico combines these needs for residential work: drop symbols on the PDF, add per-room zones and draw the connections you need to make the document usable.

How to pick the right online tool for residential work

For a home installation, prefer a tool that accepts a PDF floor plan, ships symbols consistent with IEC 60617 — the international set the Australian and New Zealand drawing conventions are based on — and exports a clean document.

A generic drawing tool can work, but a specialised tool dramatically cuts the time you spend re-creating symbols, a legend and a summary.

  • Direct PDF floor plan import.
  • Electrical symbol library.
  • Per-room and per-floor management.
  • PDF export with legend.

    Add the important links between controls, lights and dedicated circuits.

  5. 5

    Export the PDF

    Generate a shareable document for your electrician or client.

Frequently asked questions

Can I build an electrical schema without installing software?
Yes. A web tool like Planelico lets you build an electrical schema right in the browser, starting from a PDF floor plan, and then export the result.
Is an online electrical schema enough for a real project?
It is often enough to scope the need, request a quote and work with the electrician. The licensed electrician remains responsible for the design checks, the installation and its certification.
Do I need to know how to use a CAD tool?
No. For a home, a specialised tool with drag-and-drop electrical symbols is generally faster than a generic CAD application.
