Consumer unit and fuse board label maker

Label My Board lays out your consumer unit or distribution board exactly as it's wired and prints colour-coded labels that fit it. It works with DIN-rail boards, the kind used across the UK, Ireland, Europe, Australia and New Zealand, whether you're an electrician labelling a new install or a homeowner finally working out which breaker is which.

How it works

  1. Build your board. Add breakers left to right along each rail, and rows down the board, just as they sit in the box.
  2. Name each circuit. Tap a breaker and type what it feeds. The colour and icon follow the name, and the label appears under the breaker as you type.
  3. Print and cut. Download a PDF, print it at actual size and cut along the lines.

What you can print

  • Label strips for the window on the board's cover, one per row, sized to the row's exact width.
  • A circuit list to keep inside the board door or with the house papers.
  • A test-fit sheet with strips at several heights, so you can find the one that fits before printing the real thing.

Made for real boards

Main switches, RCDs, RCBOs, MCBs, surge protectors, AFDDs, isolators, timers and blanks are all available, 1 to 4 modules wide. Labels are laid out in millimetres and written in CMYK so colours print strongly on a home inkjet.

Questions

Will the labels fit my board?

Label My Board works with DIN-rail boards, where each module is usually 17.5 mm wide, and you can change the module width if yours differs. Label windows vary a lot in height, so print the test-fit sheet first: it shows the strip at several heights so you can pick the one that fits your board.

How do I print the labels at the right size?

Print the PDF at Actual size or 100%, never Fit to page. Every page has a 100 mm ruler: measure it before cutting. If it isn't exactly 100 mm, your printer scaled the page.

What do the label colours mean?

Each colour shows what a circuit feeds: red for the main switch, slate for surge protection and RCDs, yellow for lighting, blue for sockets, orange for kitchen appliances, purple for heating and water, green for outdoor and outbuildings, and teal for solar, batteries and EV chargers. The name on each label is always the authority, and labels stay readable in black and white.

Do I need an account?

No. Your board is saved in your browser on this device. Nothing is uploaded unless you save a .board.json file or copy a share link.

Does it work with North American breaker panels?

No. Label My Board is for DIN-rail consumer units and distribution boards, as used across the UK, Ireland, Europe, Australia and New Zealand.

Does Label My Board check my installation?

No. It only makes labels. Electrical work must be carried out by a qualified, registered electrician.
