What Is Quadruplex Wire Used for?

Ewcswire04 Jul, 2025Business

To put things as simply as possible, quadruplex cable is a cable that contains three phase conductors in parallel, along with a ground or neutral wire for a total of four, hence the name. The neutral wire is typically marked prominently to distinguish it, although sometimes it is a bare lead. This differentiates it from triplex wire which is similar, but which has two conductors and a ground or neutral wire, for a total of three.
