ElectroSchema
Residential electrical installation design.
Fast. Correct. I7-compliant.
The only web app for licensed electricians in Romania that automates electrical installation design: I7 compliance, 2D floor plan, visual consumer unit and a complete bill of materials — fast, correct and professional.
Built for licensed electricians
ElectroSchema is aimed at licensed electricians who design electrical installations for houses and flats. It is not a repurposed architecture tool and it is not intended for industrial installations. It is a vertical tool, built exclusively around the specifics of residential electrical installations in Romania.
Independent electricians
You design on your own and need speed and accuracy. ElectroSchema removes the repetitive manual work.
Electrical contractors
Small team or large — projects are stored in the cloud, accessible from anywhere, with no lost local files.
Installation designers
Complete technical documentation: 2D plan, visual consumer unit, BOM, I7 compliance — everything the client requires.
For the professional electrician
The difference between a good electrician and one clients keep recommending
The app doesn’t design in your place — it helps you miss nothing important, turn up prepared and leave behind a correct installation.
No more materials forgotten off site
The bill of materials automatically works out everything you need from the context of the installation: cables with spare allowance, corrugated conduit by diameter, Wago connectors per junction box, cable lugs, mounting boxes, EPD, ECUB. You turn up at the client prepared — no more going back twice for a box of connectors.
Spot problems before it’s too late
Missing RCD protection, overloaded circuit, undersized cable, equipment in a prohibited IP zone next to the bath/shower, uncoordinated cascaded RCDs, incomplete two-way/intermediate switching chain. 55 automatic checks show you what endangers lives — before energisation, not after.
Balance the phases from the first draft
The power distribution across R, S, T is visible in real time, for every consumer unit. You correct imbalances at the design stage, not after the cables are pulled — avoiding overvoltages, burnt-out equipment and awkward conversations with the client.
Know exactly what’s done and what’s left
Mark circuits as “installed” as you complete them. On a site with a ground floor, two upper storeys and dozens of circuits, you no longer mix up what’s finished with what’s pending. Filter instantly: all / not installed / installed.
Consumer unit documented visually
The visual consumer-unit editor shows every DIN row, every protective device with its parameters, and the upstream–downstream hierarchy between protections. Any electrician working on it later understands the installation immediately — and the client can see you know what you did.
Socket-outlet counts meet the code automatically
Validation checks the socket-outlet density per room against I7: whether the kitchen has at least 3 socket-outlets, whether hallways have their own lighting, whether utility rooms have a service socket-outlet. Details that make the difference at handover.
Features
Everything you need in a single app
Interactive 2D editor
Draw rooms, doors, windows and storeys on an intuitive canvas. Dimensions appear in real time; the plan takes shape exactly as it does on site.
Specialised electrical equipment
A complete library: socket-outlets, switches, lighting points, household appliances, consumer units, MCBs, RCDs, surge protective devices — each with its standardised symbol.
Colour-coded cable routing
L (brown/red), N (blue), PE (green-and-yellow), R/S/T conductors — each with its cross-section in mm², conductor material (CU/AL) and length calculated automatically from the 2D plan.
Visual consumer unit
Drag-and-drop consumer-unit editor: DIN rows with colour-coded L/N/PE busbars, a clear upstream–downstream hierarchy, MCB/RCCB/RCBO/SPD configuration with all technical parameters.
I7-2011 code validation
Automatic checking of 55 rules from the I7-2011 wiring code plus the 2023 amendments: cable cross-sections, RCD protection, socket-outlet density, bathroom IP zones, two-way/intermediate switching wiring, cascaded RCD coordination. Every error cites the exact article and proposes the correct fix.
Bill of materials (BOM)
The automatic list includes cables (with spare %), corrugated conduit by diameter, Wago 221 connectors per junction box, cable lugs, mounting boxes, EPD and ECUB — all calculated from the context of the installation, without you having to ask. CSV export for ordering or quoting.
Detached diagram per room
Automatic generation of the circuit diagram in detached representation: L/N/PE busbars, IEC 60617 symbols, terminal and switch numbering. PDF export with circuit legend and engineering title block.
Single-line diagram per room
Automatically generated single-line tree: MCB → junction boxes → switches → loads, with /N notation on every segment. Dynamic layout, SVG/PDF export with IEC 60617 symbols.
Composite diagram per room
All the room’s circuits brought together in one drawing: L/N/PE busbars, the MCBs from the consumer unit, loads and junction boxes. Automatically detects junction boxes carrying 2+ circuits and marks them explicitly. PDF export with the circuit table and the multi-circuit junction box section.
Diagnostics and phase balancing
Power distribution across phases R, S, T per consumer unit. Green/amber/red visual indicator for three-phase imbalance. Fix it before you install.
Smart home ready
Wiring prepared for Shelly/Sonoff systems: an N+PE run through the switch is included automatically when you enable the “Smart-ready” option.
Workflow
From zero to a complete project in 7 steps
Create the project
Name + site address. The editor opens with the Ground floor active.
Draw the plan
Rooms with real dimensions, doors, windows, additional storeys.
Place the equipment
Socket-outlets, switches, consumer units, lighting points — from categorised palettes.
Route the cables
Colour-coded conductors with cross-section, material and orthogonal routing.
Configure the consumer units
Drag-and-drop protective devices onto DIN rows, set rated and residual currents.
Check compliance
One click — an I7 report with errors, warnings and cited articles.
Export the materials
Complete BOM with quantities, CSV for ordering or a client quotation.
Competitive advantages
What sets it apart from other solutions
I7 code natively integrated
There is no other electrical design application in Romania that automatically checks compliance with the I7-2011 wiring code and cites the exact article for every issue found.
Designed exclusively for residential work
It is not a repurposed AutoCAD or a stripped-down industrial tool. ElectroSchema was built from the ground up for houses and flats — with the room typology, mounting heights and circuits specific to residential installations.
Visual consumer unit with a clear hierarchy
Upstream–downstream relationships between protective devices are shown directly in the consumer-unit editor. You see instantly which breaker protects which circuit and whether the RCD correctly covers the MCBs on its row.
Cable lengths calculated automatically
You draw the cable on the 2D plan and its length is calculated from the rooms' real distances plus the mounting heights defined for each room. No manual measuring, no guesswork.
Inter-floor connections
Cables between consumer units on different floors are treated as distinct entities, with the length calculated from the horizontal distance plus the height of the pass-through in the floor slab.
Romanian language and terminology
The entire interface, all error messages and all reports are in Romanian, using the terminology used on site and in the Romanian codes — not machine translations.

Compliance with the I7-2011 wiring code
The I7-2011 code for electrical installations, amended in 2023, defines the mandatory rules for designing residential electrical installations in Romania. ElectroSchema automatically checks compliance with 55 rules — from minimum conductor cross-sections and RCD coordination through to bathroom IP zones and the correct wiring of two-way and intermediate switching circuits. All 55 checks cite the exact article of the code and propose a concrete fix.

Zones 0/1/2 around the bath/shower — prohibited equipment, insufficient IP rating, water heater without a dedicated circuit, water heater without a 30 mA RCD (Art. 7.7 + 5.3.2.4 of I7)
Consumer unit
Protection per circuit, PE protective conductor, upstream–downstream selectivity between protective devices
Two-way / intermediate switching wiring

Rules that cannot be checked automatically from the 2D plan — such as workmanship quality, protective conductor continuity or insulation resistance — are included in the app as a checklist for the electrician, with the code article cited, so that nothing in the code is missed at the installation handover.
