Thhncu-generic tffn16strblk2500r Tffn 16 Awg Wire 2500ft

Product Description

The THHNCU-GENERIC tffn16strblk2500r is a 16 AWG stranded copper building wire rated for general wiring applications in conduit. Insulated with PVC and jacketed with a nylon outer layer, this wire carries a TFFN designation and is rated for 600 volts and 90 degrees C. The 26-strand configuration provides flexibility during pull-through in conduit runs. Each reel contains 2500 feet of black wire, making it well suited for large commercial or multi-unit residential wiring projects where bulk supply reduces job site waste and reel changes.

This wire is used in conduit installations for branch circuit and control wiring in residential, commercial, and light industrial settings. The black insulation color is standard for hot conductors in single-phase and three-phase systems per NEC color conventions. Electricians and electrical contractors typically use this wire for panel feeders, circuit drops, and motor control wiring where a flexible stranded conductor is preferred over solid wire.

Key Features

• 16 AWG stranded copper conductor with 26-strand configuration for flexibility
• PVC insulation with nylon jacket meets TFFN designation requirements
• 600-volt rating suitable for standard branch circuit applications
• 90 degrees C temperature rating for use in dry locations
• 2500-foot reel reduces reel changes on large projects
• Black insulation for standard hot-conductor identification

Compatibility

Designed for use in conduit as a general-purpose TFFN-rated building wire for 600-volt branch circuit and control wiring applications.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before making any connections. TFFN wire is rated for use in conduit and is not approved for direct burial or exposed outdoor use without appropriate additional protection. Pull tension limits for the conductor size should be observed to avoid damaging the insulation during conduit pulls.
