Everything you need

Complete electrical diagram software, no install

From single-line panel diagrams to multi-line power and control circuits, ElectroCAD covers your whole design flow.

Standard electrical symbols

Over 400 symbols (IEC): protections, motors, contactors, switchgear — aligned and ready to wire.

Smart wiring

Connection points snap automatically for clean, straight three-phase links without stray angles.

Templates and A0 to A4 title blocks

A0 to A4 title blocks, residential diagrams, panels, motor starters — start in one click.

PDF, SVG and PNG export

Export to high-resolution PDF, SVG or PNG, ready for print or documentation.

100% in-browser

No install, no plugin. Your diagrams are saved in your browser, not on our servers.

Read-only share link

Generate a view-only link to share a diagram without granting edit access.

Use cases

What you can draw with ElectroCAD

Home electrical panel (single-line)

Main breaker, 30 mA residual-current devices, lighting with one-way or two-way switching, sockets grouped per circuit, and a dedicated circuit for each appliance: cooktop, oven, water heater, EV charger, heat pump.

Three-phase motors: power and control (multi-line)

Direct-on-line starting in one or two directions (motor reversing), star-delta, stator resistance starting, DC injection braking. Power circuit marked L1/L2/L3 (Q, KM1, F1, M 3~) and control circuit with self-holding, interlocking and timers.

Solar PV installation

Panel strings, DC disconnector, one or more inverters, AC breaker, meter, battery and grid connection, including solar carports.

Layout and documentation

A0 to A4 title blocks, grid-aligned symbols, PDF, SVG or PNG export for your files, and a read-only share link to get a diagram reviewed.

FAQ

Frequently asked questions

Is ElectroCAD free? Do I need an account?

Yes, ElectroCAD is free and works without signing up: open the editor and start drawing.

Single-line or multi-line diagram: what is the difference?

A single-line diagram shows each circuit as one line, whatever the number of conductors: it is the overview of an electrical panel. A multi-line diagram draws every conductor (L1, L2, L3, N) and is used for power and control wiring, for example of a three-phase motor. ElectroCAD handles both.

Are the diagrams compliant with electrical codes such as NF C 15-100?

ElectroCAD helps you draw; it does not check compliance. The AI assistant applies a few common distribution rules (circuits grouped under 30 mA residual-current devices, at most 8 sockets per circuit), but sizing and compliance must still be validated by a professional.

Which formats can I export to?

PDF, SVG or PNG for print and documentation, and ElectroCAD's XML format to reopen the diagram later.

Where are my diagrams stored?

In your browser: your diagrams are not saved on our servers. The text of your requests to the AI assistant is sent to the generation service, and the Microsoft Clarity analytics tool records browsing sessions, including the assistant window.

How do I share a diagram?

Generate a view link: the diagram is encoded in the link itself, and whoever opens it can view it without being able to edit it.
