Thhncu-generic tffn16strred2500r Tffn 16 Awg Wire 2500ft

Product Description

The THHNCU-GENERIC tffn16strred2500r is a single-conductor TFFN/Nylon-jacketed building wire rated for 600 volts and 90 degrees C. It features a 16 AWG stranded copper conductor with a 26-strand configuration and PVC insulation covered by a nylon jacket. The red color coding aids circuit identification in panel wiring and branch circuit work. This reel contains 2500 feet of continuous wire, making it well suited for larger electrical installations where minimizing splices is a priority. Licensed electricians and experienced electrical contractors are the primary installers of this wire type.

TFFN wire is used in conduit-fed branch circuit wiring, fixture wiring, and control wiring applications in both residential and light commercial construction. The nylon jacket provides additional abrasion resistance compared to standard TFF wire, supporting use in dry and damp locations where wire may be pulled through conduit or raceways. The 16 AWG gauge is common in lighting circuits, low-load branch circuits, and control panel wiring where conductor ampacity requirements fall within the 16 AWG range per NEC tables.

Key Features

• 16 AWG stranded copper conductor with 26-strand configuration for flexibility during installation
• PVC insulation with nylon jacket meeting TFFN designation requirements
• 600-volt rated for standard branch circuit and control wiring use
• 90 degrees C temperature rating supports higher conduit fill ampacity calculations per NEC
• Red jacket color coding for circuit identification and phase marking
• 2500-foot continuous reel reduces splice points on large runs

Compatibility

Designed for use in conduit, raceways, and other recognized wiring methods where TFFN or THHN-type single-conductor building wire is specified. Suitable for dry and damp locations in residential and light commercial electrical systems.

Installation Notes

Installation of TFFN branch circuit and control wiring must comply with NEC Article 310 and applicable local electrical codes. De-energize all circuits and verify with a meter before working on any existing wiring or terminating new conductors. A licensed electrician should size conduit fill, determine conductor ampacity, and make all terminations. Avoid exceeding the wire's minimum bend radius during pulling to prevent insulation damage.
