Thhncu-generic tffn16strred500r Tffn 16 Awg Wire 500ft

Product Description

The THHNCU-GENERIC tffn16strred500r is a TFFN-rated, 16 AWG stranded copper building wire on a 500-foot spool, finished in red insulation for circuit identification. The conductor is fully annealed bare copper with a 26-strand configuration, making it flexible and well-suited for pull-through-conduit work. PVC insulation with a nylon outer jacket meets TFFN designation and carries a 600-volt rating and a 90 degrees C dry temperature rating. Electricians and panel technicians reach for this type of wire on light-commercial and residential branch circuit, control circuit, and fixture wiring runs where conduit installation is required.

This wire is appropriate for use in dry locations where TFFN or THHN-style conductors are specified. Typical applications include conduit fills in junction boxes, panel feeders for low-ampacity branch circuits, control wiring in HVAC equipment, and fixture whip assemblies. The red jacket color is commonly assigned to specific phase legs or control circuits to aid in job-site traceability and inspection compliance. The 500-foot spool quantity suits full-run pulls on medium-scale commercial or multi-unit residential projects without mid-run splices.

Key Features

• 16 AWG fully annealed bare copper conductor with 26-strand configuration for flexibility during conduit pulls
• TFFN type rating with PVC insulation and nylon jacket for dry-location installations
• 600-volt rating suitable for standard branch circuit and control circuit applications
• 90 degrees C dry temperature rating for use in warmer enclosure environments
• Red insulation for phase or circuit identification per job-site color-coding practice
• 500-foot spool length reduces the need for mid-run splices on longer pulls

Compatibility

Designed as a standard TFFN 16 AWG stranded copper wire suitable for dry-location conduit installations in residential, light-commercial, and HVAC control wiring applications where 600-volt rated conductors are specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local amendments. Confirm that conduit fill ratios comply with NEC Chapter 9 tables before pulling multiple conductors. De-energize and lock out all circuits before terminating or splicing conductors. This wire is rated for dry locations only and must not be installed in wet or damp environments without verification of appropriate wet-location ratings.
