Main Isolator (Grid)

This label carries the engraved wording "Main Isolator [Grid]", giving the grid-side main isolator its own clear identity on a switchboard where multiple isolators can otherwise cause confusion. It's built for electricians and switchboard fitters who need permanent, unambiguous circuit identification in place of handwritten notes or generic tags that leave installers guessing which isolator governs grid supply.

The white Traffolyte material carries the engraved wording as a permanent cut, rather than a surface print, so it stands up to handling, cleaning and general switchboard wear without the text fading or lifting over time. Measuring 18mm x 18mm, the tag is sized to sit comfortably within a standard label run, keeping multiple isolator markings legible and consistent across a busy panel without overwhelming the surrounding layout.
