Cable Markers & Identification

Cable Markers & Identification: Durable Labelling Solutions for Circuits, Cables and Switchboards

Cable markers and identification labels keep circuits traceable long after an installation is signed off, which matters the moment a fault call comes in months or years later. This range covers clip-on letter, number and symbol markers, permanent ID tags, labelling tape and accessories such as blank clip-in labels for custom text, suited to switchboards, distribution boards and cable trays alike. For a closer look at keeping boards compliant and easy to trace, see our guide to labelling switchboards correctly.

What's in This Range

• Brass cable markers — a permanent metal option for cables that need to hold their ID for the life of the installation.
• Cable end marker sets — numbered 0–9 clip-on sets for fast, consistent circuit numbering across a board.
• Cable ID labelling tape — printable tape for continuous runs where individual clip markers aren't practical.
• Marker positioning tool — a dedicated fitting tool that speeds up placing clip-on markers accurately.
• Cable marker transporter — a loading strip for 15–25mm markers that keeps bulk labelling jobs moving.
• Letter cable markers — 15–25mm clip-on letter sets for phase, circuit or terminal reference coding.
• Colour-coded cable ID labels — 10mm colour-coded labels for quick visual sorting on busy cable runs.
• Die-cut circuit ID label kits — a full circuit identification system designed for board directory labelling.

Who Uses This

Electrical contractors reach for clip-on letter and number markers during switchboard upgrades and commercial fit-outs, where every circuit needs to match the board directory before handover. Data and comms technicians favour labelling tape and colour-coded labels for patch panels and structured cabling runs in offices, schools and warehouses. On larger infrastructure and civil works, brass markers and die-cut circuit ID kits get specified where labels have to survive years of plant vibration, weather exposure or repeated panel access.

Cable Markers & Identification — Common Questions

Which cable marker size should I use for my cable diameter?

Marker size needs to match the cable's outer diameter so the clip grips securely without splitting. Smaller cables and control wiring typically take 4–6mm or 5–15mm markers, while general power cable and switchboard tails suit the 15–25mm range. If a job mixes cable sizes, a clip-in tag holder gives more flexibility than a fixed-size marker.

Do I need different markers for earth or symbol identification?

Yes — earth conductors and specific functions like AC or DC circuits are best identified with dedicated symbol markers rather than letters or numbers, since the symbol is recognisable at a glance during fault-finding or an inspection. Mixing symbol markers with your letter and number sets on the same board keeps identification consistent for anyone working on it later.

How long do cable markers last in industrial or outdoor environments?

Lifespan depends heavily on material and exposure — plastic clip-on markers hold up well indoors but can fade or become brittle under prolonged UV or extreme temperature swings, while brass markers are built for long-term outdoor or industrial use. For a wider comparison of tag and marker materials for different environments, our article on electrical cable tags breaks down which type suits which application.
