Export and Print

ElectroBoard lets you export a panel project in several formats for use on site, and save the project to a file to hand off to colleagues or keep as a backup.

---

Panel Diagram PDF#

The main export is a PDF with a visual diagram of the panel. Open it from the "Export" menu in the toolbar.

What's included:

• An SVG image of the panel with every device, busbar, and wire — in landscape orientation
• Load labels above each rail — the full name (Refrigerator, Kitchen lighting, and so on) in the style of standard DIN stickers, with control over orientation, font, and which parts are shown (type / rating / phase). Configured on the "Labels" page (/labels) — changes apply automatically to the wiring diagram too. If no name is set, the label is hidden automatically.
• The project name and the network parameters

The PDF is produced through the browser's standard print flow, so you can save it as a file or print it directly.

Wiring Diagram (Connection Schema)#

A separate printable section with every wire and its number — what the electrician needs at the panel to see which wire goes where.

What it shows:

• The panel with all wires between devices, busbars, and combs
• Wire number (W-number) next to each terminal — a "pill" label with a leader to the exact terminal. The numbering is stable — the same number appears on the diagram and in the connection list
• Labels are laid out so they don't overlap one another or sit on busbar bodies; on devices they stack as a ladder in terminal order with a comb connector, so the leaders don't cross
• In/out direction: a solid label border = an input into the device, a dashed one = an output; devices also get an arrow on the connector (filled = input, outline = output)

The marking scheme can be switched (a selector above the diagram) — the same modes as in the editor:

• W001 number — a sequential wire number (default)
• Terminal address — each end shows the address of the opposite terminal (e.g. QF1:2)
• Nodes L1-1 — numbering by potential: every terminal of one electrical node carries the same number (L1-1, N-2), as on an industrial wiring diagram. A terminal is marked with its real number (1/2 top/bottom per IEC), with no prefixes

The label font size is also adjustable (7–16 pt).

The connection list prints on its own page — a table of every wire: each row is one physical wire (from-terminal → to-terminal, cross-section, length). In "Nodes" mode the rows are grouped by a node column (L1-1), so you can see which wire goes to which terminal. Numbers and lengths come from the same source as the diagram.

Bill of Materials (BOM)#

The BOM (bill of materials) is a table listing every device in the panel. It is generated together with the PDF and shown in portrait orientation.

What's included for each device:

• Type and name
• Rating
• Number of modules on the DIN rail
• Characteristic (tripping curve) — where applicable
• RCD type and residual operating current — for RCDs and RCBOs
• Cable (cross-section, installation method, length) — for internal cables the length is filled in automatically from the router, marked "auto"
• Cable composition — if the N or PE cross-section differs from the phase one, it is stated separately, for example 5×16 (N 25) or 5×25 (PE 16); the same in the wire list
• ATS / changeover input cables (main + reserve — on separate rows)
• Power-source role — for incoming devices with an assigned role (grid / generator / inverter, and so on)

Busbars in the BOM: the specification includes a separate section listing PE/N busbars and combs — type, number of terminals, rail. This lets you account for the busbars when ordering materials.

PDF alignment: the BOM table is automatically fit-and-centered on the page regardless of the number of rows.

Cable cores in the BOM: every cable is shown in the n×s mm² format — the number of cores and the cross-section. The summary adds a separate table aggregating by cable cross-section (number of runs, total length).

Conductor material in the BOM: if the material of an automatically sized cable is not yet confirmed and copper and aluminium would give different cross-sections, the BOM and the wire list print both options — for example Cu 5×10 / Al 5×16 — so that copper nobody chose is never printed. Once the material is confirmed, one value remains. The material comes from the panel rule, so it is the same for device, comb and bar cables (see Cable System).

The BOM is convenient for putting together an order at the electrical store — you see the exact list of what to buy.

Bill of Materials — Download (XLSX / CSV)#

A dedicated procedure for suppliers — the "📥 Specification" button on the export page opens a menu with a format choice:

• Excel (XLSX) — a rich format with coloured tabs, frozen headers, formulas, and filters. It is built as a full Excel table — add your own rows at the bottom, and the formulas (quantity × price) and the dashboard on the Summary sheet recalculate automatically.
• CSV — a universal format for importing into Google Sheets, Numbers, or accounting systems (UTF-8 BOM, ; separator, decimal comma — tuned for the regional Excel format).

File structure (5 sheets):

• Devices — modular devices, with filters by category / type / manufacturer / supplier / status / location
• Cables — cross-section, marking, flexibility class, runs, length; manufacturer and part number (also for a bus bar's feeder cable — the same appear in the cables table in the PDF)
• Busbars — PE/N and L+N, with material (Cu / brass / Cu + gold plating)
• Combs — pin-combined, with the power source and the conductor combination
• Summary — quantity metrics, cost (SUM across sheets), and order progress (COUNTIF by status, % complete, items with no price)

Columns to fill in (empty by default, complete them in the spreadsheet):

Field	What to enter
Manufacturer	ETI / Hager / Schneider / ABB / Legrand — the brand
Model	ETIMAT 6 / MTN116 / iC60H — the series/line to look up an SKU
Part number	The supplier's exact SKU (KZS-1M, A9F77116)
Supplier	Your distributor or store
Unit price	Price per unit (retail, tax-inclusive where relevant)
Sum	Auto-formula quantity × price (XLSX) — enter the price, get the sum
Status	Not ordered / Ordered / Delivered / Installed (XLSX drop-down)
Order date	dd.mm.yyyy
Location	"Panel 1 / DIN 3 / pos. 5" — where to mount it
Notes	Replacements, RMA, a product link

Conditional formatting highlights rows automatically:

• Colour by status — each status ("Not ordered", "Ordered", etc.) gets its own background.
• Red — the row has a device type but no price filled in (a reminder to complete it).
• Bold amber — a rating of 63 A or more (high-power devices worth a closer look).
• Grey — a zero total (not yet calculated).
• A row with the "Installed" status is fully dimmed, to set finished items apart.

Panel Labels#

Printable labels for marking the breakers inside the panel. Open them from the "Export" menu → "Labels".

Each label contains:

• The device name (for example, "Kitchen sockets")
• The rating (for example, "16 A")
• The phase (L1, L2, or L3)

The labels are print-optimized — sizes are given in millimetres to match the standard windows on the panel cover. Print, cut out, and slot them into the panel.

Label generator features:

• Label width — 18.5 mm (the standard DIN-module width); presets of 17.5 and 18 mm are also available
• Orientation — vertical by default (text bottom-to-top), switchable to horizontal
• Adaptive height — the label height adjusts to the length of the name text
• Side column — a short vertical column (phase or rating) sits beside the main text rather than on a separate line — saving space
• The font is optimized for fine print: crisp and legible even on 18.5 mm strips
• Labels for the PE/N busbars are included as a separate section
• Check against the device body — the label width is calculated from the device width in modules. If the measured device body does not match it (for example, a 43.75 mm socket against 36 mm of space), a warning with a list of such devices appears above the labels; you can type the width of an individual cell by hand — click the cell

Project File (.eboard)#

ElectroBoard supports saving and opening projects in its own .eboard format — an ordinary JSON file with all the panel data.

Why You'd Use It#

• Hand a panel to a colleague — send the file over a messenger or by email
• A backup — keep a local copy on your computer
• Move between accounts — open the panel under a different login
• An archive of completed jobs — keep a panel after the site is done

Save a Project to a File#

1. Click the pill with the project name at the left of the toolbar (on a phone — the "Project" sheet)
2. Choose "Save .eboard"
3. The file Project_name.eboard is saved to your downloads folder

Open an .eboard File#

1. Click the pill with the project name at the left of the toolbar (on a phone — the "Project" sheet)
2. Choose "Open .eboard"
3. Pick the file in the file dialog
4. A confirmation appears — click "Open"
5. A new project is created from the file's data, and you are taken to it

⚠️ Note: Opening an .eboard file always creates a new project. Your current project is left untouched.

If the file is corrupt or in an incompatible format, an error message appears, and your current project stays unchanged.

Single-Line Diagram (SLD)#

The single-line diagram is a standard technical document with IEC symbols, needed for handing over sites and for project documentation.

Open it from "Export ▾" → "SLD".

The diagram shows every device with IEC symbols (MCBs, RCDs, RCBOs, meters, and others), the L/N/PE phase busbars, protection groups, and labels with ratings.

More detail: Single-Line Diagram

How to Export (PDF, BOM, Labels)#

1. Click "Export ▾" in the toolbar (on a phone — the ≡ menu → "Export")
2. Choose the option you need:
   • PDF panel — opens the export page with a preview of the panel diagram, the wiring diagram, and the specification
   • Labels — opens the page with the printable labels
   • SLD — opens the single-line diagram
3. Use the print panel on the export page (see below) or the browser's standard print (Ctrl+P)

Tip: To save as a PDF — in the print dialog choose "Save as PDF" instead of a printer.

Print Panel and Page Orientation#

The export page has a two-tier print bar:

Tier 1 — settings:

• Page orientation — Auto (derived from the diagram's proportions), Landscape, or Portrait
• Wiring-diagram label settings — the label content and the font size (see the "Wiring Diagram" section)

Tier 2 — print: a separate button per section, each printed in the orientation best suited to its content:

• Print panel — the panel diagram only
• Print wiring — the wiring diagram + the connection list
• Print labels — the panel labels (forced landscape — wide rails don't fit portrait)
• Print spec — the BOM (portrait)
• 📥 Specification — XLSX / CSV download
• Print all — every section in one document

Each section prints on its own page and auto-scales to A4.

Exporting from a Shared View#

If someone has sent you a link to a panel for viewing, you can export the PDF and the labels as well. The "Export" menu is available in view-only mode too.

In a shared view the wiring-diagram labels are shown with default settings: your personal label settings are stored only in your own browser, so the other person sees the standard look.
