Electrician’s 3-Phase Wiring Color Reference Sticker – Black • Red • Blue

This professional-grade reference sticker is designed to make 3-phase wiring colors clear and accessible on the job. Featuring the standard Black, Red, and Blue phase color chart, it’s a quick visual aid that helps reduce errors and saves time in the field.

Made from heavy-duty, waterproof, and UV-resistant vinyl, it adheres securely to toolboxes, panels, binders, water bottles, phones, or hard hats.

As an electrician myself, while terminating wires in panels and disconnects, I like having a colorful reference chart on my hard hat and other item instead of referring to my tape measure or doing the divide by 6 / remainder method.
