PVC Tape: the Colour Code by the Roll

The 19mm x 33m standard in every declared colour: Unicrimp’s rolls run black, blue, brown, white and yellow, and Greenbrook’s Norslo line matches with black, blue, brown, grey and green/yellow, so line, neutral, earth sleeve marking and every phase convention pulls its identification off the same shelf.

Frequently Asked Questions

Identification and dressing: marking conductors to the colour code and insulating and tidying where a wrap is the right tool.

The harmonised code: brown for line, blue for neutral, grey for the second phase set and green/yellow reserved for earth.

It marks, sleeving dresses: use each per the practice the inspection expects.

Adhesive and stretch differ: branded electrical grades hold their wrap and colour over years, which is what these are.

Half-lap under tension: the stretch activates the adhesive and the overlap seals the wrap.

The marking moment: conductor identification comes up mid-job, not at the wholesaler.
