Electrical panels, distribution boards and switchgear need clear, durable labelling - both for day-to-day operation and because UK wiring regulations expect certain information to be clearly and permanently identified. This guide covers what's generally expected on electrical panel labelling and where BS 7671 (the IET Wiring Regulations) comes in, though for a specific installation you should always confirm exact requirements with a qualified electrician or your electrical consultant, since requirements vary by installation type and BS 7671 is periodically updated.
Why Panel Labelling Is a Compliance Issue, Not Just a Convenience
BS 7671 requires that certain information about an electrical installation - such as circuit identification at distribution boards, warnings about isolation, and details of the maximum demand or supply characteristics - be clearly displayed so anyone working on or near the installation can identify it safely. Beyond the specific regulatory requirements, unclear or missing panel labelling is also one of the most common issues flagged during periodic electrical inspections, so getting it right the first time avoids repeat remedial work.
What's Commonly Labelled on Electrical Panels
- Distribution board and circuit identification (e.g. "DB1", "Circuit 4 - Sockets Office")
- Main isolator and emergency stop labelling
- Warning labels (e.g. "240V Supply", "Danger - Isolate Before Opening")
- RCD test labels and periodic inspection date labels
- Voltage and supply characteristic labels where required
The exact wording and format required depends on the installation, the type of board, and current BS 7671 guidance - your electrical contractor or consultant will usually specify what's needed for a given job.
Traffolyte: The Standard Choice for Panel Labels
Traffolyte is the material most commonly used for electrical and control panel labelling, for good reason - it's available in the standard colour combinations electrical labelling typically calls for, engraves cleanly with strong contrast, and holds up well indoors on panels and distribution boards. For panels in harsher or outdoor environments, stainless steel or aluminium labels are sometimes used instead.
Labelling a Whole Board or Site Consistently
Most electrical contractors need a full set of labels for a board or site at once, rather than one-off labels - main isolators, individual circuits, warning labels, and periodic inspection labels all needing to be consistent in size, colour and wording across the job. Sending a full schedule of what's needed, rather than ordering piecemeal, makes it easier to keep everything matching and means we can quote and produce the whole set together.
