This THHN building wire provides a 12 AWG stranded copper conductor with a thermoplastic high heat-resistant nylon jacket. The stranded construction offers greater flexibility compared to solid wire, which simplifies installation in conduit and junction boxes. The PVC insulation and nylon outer sheath provide protection against abrasion and heat up to 90°C in wet or dry locations.
This wire is suitable for general purpose wiring in residential, commercial, and industrial applications. It is commonly used for branch circuits, feeders, and control circuits. The black insulation identifies it as an ungrounded conductor within a system.
