Conductor colours

Inside the jacket, two languages

Strip a North American cord and you find black, white and green. Strip a harmonized one and you find brown, blue and green with a yellow stripe. Same job, different alphabet — and a cord built for export must speak the one its destination reads.

The two codes

North American (NACC)

  • Black — line
  • White — neutral
  • Green — ground
  • Red — second line
  • Blue — third line

Harmonized (HAR)

  • Brown — line
  • Blue — neutral
  • Green/yellow — earth
  • Black — second line
  • Grey — third line

On the reels here

The SJT, SJTOW, SJOOW and SOOW families carry the North American code (NACC on the label). The H05VV-F and H07RN-F reels carry the harmonized code. The universal reel carries the harmonized colours, as its HAR listing requires, and is accepted under UL and CSA with them.
