Blue Phase Discs

Our Blue Phase Discs make electrical phase identification clear, accurate, and compliant with standard colour-coding practices. They’re widely used by electricians, contractors, and maintenance teams working across construction sites, facilities, and MRO operations.

Supplied on easy-to-handle sheets, these discs are simple to store, transport, and keep organised. The sheet format ensures you can quickly select the right size and apply it without wasting time on-site.

Manufactured from self-adhesive vinyl with a permanent adhesive, they adhere securely to clean, dry surfaces such as cables, panels, and distribution boards. The bold blue colour provides high visibility, helping to prevent wiring errors and maintain safe electrical systems.

Available sizes:

• 10mm diameter

• 15mm diameter

• 20mm diameter

Typical applications include:

• Phase marking in electrical distribution systems

• Colour-coding for compliance with wiring regulations

• Identification in control panels and switchgear

• Long-term labelling in industrial and commercial environments

We offer fast delivery and bulk order discounts, ensuring you can keep your marking supplies well-stocked for ongoing and future projects.
