Explaining Part Numbers

Cerrowire® Part Numbering Conventions

1. A single conductor, finished goods part number consists of the product line code, a dash, size/construction code, color code and a finished put-up suffix:

{product line} - {size/construction}{color}{put-up}

Example:  12 strand THHN, blue, 500 ft spool would be "112-3604J"

2. A multi-conductor, finished goods part number consists of the product line code, a dash, size/construction code, number of conductors and a finished put-up suffix:

{product line} - {size/construction}{#conductors}{put-up}

Example:  14-3 NM-B w/ground, 1000FT reel would be "147-1403K"
