Wired for Purpose: Every Cable, Every Function

Wire and cable types show up everywhere in the field, and knowing the basics helps you choose the right product, avoid installation issues, and keep systems running reliably. This glossary highlights the most commonly used cable types across power, low‑voltage, data, and control work—giving you a quick, practical reference for the options you’ll encounter most on the job.

With this foundation, the glossary below outlines the key wire and cable types used across power, data, control, and low‑voltage work—highlighting their basic characteristics and common applications to support clearer selection and safer installations.
