01
Set the panel basics
Name the project, choose 1 or 3 phases, set the incoming current, enclosure width and voltage standard.
From an idea to a panel you can inspect
Build an electrical panel without losing the logic behind it.
Voltcraft turns rooms and electrical loads into a calculated panel, a wiring view, an editable layout and an interactive 3D model. This guide shows what to do, what every result means and what Pro unlocks.
Calculated 2D panel
Protection groups, DIN layout and cable routes remain readable as one system.
The basic workflow
Four steps to your first calculated panel
You can test one 1-phase panel as a guest. Register before starting important work so your project is stored in your account.
02
Add rooms and loads
Create floors and rooms, then add sockets, lighting, appliances and other consumers. Adjust watts, circuit breaker rating and RCD sensitivity when needed.
03
Choose equipment and mode
Select the devices you want in the panel and choose Realistic, Maximum safety or Economy calculation.
04
Calculate and review
Save the project to generate the panel. Review component placement, protective groups, wiring and estimated market prices.
Configurator + AI
Describe the building, then keep full control.
Build floors, rooms and individual loads manually, or ask the AI configurator to prepare or change them. AI suggestions update the local draft first, so you can review every value before saving.
Text, voice and floor-plan input
Watts, breaker and RCD settings
Explicit save before generation
Market estimates from the parts catalog
AI configurator
Draft changes remain reviewable
Create two floors, separate kitchen sockets and add a three-phase cooker.
I prepared the floors, rooms and loads. The three-phase option requires Pro. Review the values, then save to calculate the panel.

Your result
The calculation is a workspace, not a static picture
Open the result in 2D, inspect prices, edit the physical layout and continue in 3D. The saved schema is shared between these views.
2D panel editor
Turn the generated result into the panel you intend to assemble. Connections understand component terminals, while validation catches placement and wiring conflicts.
- Drag DIN devices between rows and slots
- Add, replace or remove compatible components
- Create terminal-aware wire connections
- Undo, redo and validate before saving
- Use the AI schema assistant for guided edits
- Keep the same saved layout in 2D and 3D
Interactive 3D
Inspect the enclosure from the front, top or perspective view. Use assembly steps, fit the panel to screen and see the same saved components and wires in depth.
Documents are coming next
The Pro button for schematic and documentation generation is already visible. It is clearly marked “Coming soon” until the export is implemented. The current 2D result can be printed or saved as PDF.
WebXR · Pro
Pro highlight
Walk around the panel in VR. Align it with reality in MR.
VR/MR is built for reviewing scale, placement and assembly in a way a flat drawing cannot provide. It works through WebXR on supported devices and remains linked to the same project schema.
- Open the panel at physical scale in a WebXR headset
- Inspect or edit with controllers and hand pinch
- Move around the workshop and recenter the enclosure
- Use Mixed Reality alignment with a real enclosure
- Switch between viewer, editor and assembly guidance
Availability depends on WebXR support in the browser and headset. Desktop 3D remains available without a headset.
