In the United States, the color code for 3-phase wiring typically follows these standards:<\/p>

  • Phase 1 – Black: This color is used for the first live or “hot” wire.<\/li>
  • Phase 2 – Red: The second phase wire is usually red.<\/li>
  • Phase 3 – Blue: The third phase wire is typically blue.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
