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"
• 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 (per IEC 60446) — the number of cores and the cross-section. The summary adds a separate table aggregating by cable cross-section (number of runs, total length).

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
• 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

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 "Export ▾" in the toolbar
2. Choose "Save .eboard"
3. The file Project_name.eboard is saved to your downloads folder

Open an .eboard File#

1. Click "Export ▾" in the toolbar
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.

How to Export (PDF, BOM, Labels)#

1. Click "Export ▾" in the toolbar
2. Choose the option you need:
   • PDF + BOM — 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.
