Tffn 16 Awg Stranded Blue Copper Wire 500ft 600V

Product Description

The tffn16strblu500r is a 16 AWG stranded TFFN-type building wire with a single fully annealed bare copper conductor insulated with PVC and a nylon jacket. Rated for 600 volts and 90 degrees C in dry environments, this wire is a standard choice for branch circuit wiring, fixture wiring, and general-purpose electrical installations. The 26-strand configuration provides flexibility during pull-through and termination. Supplied on a 500-foot spool, it suits jobs where a full reel minimizes mid-run splices. Licensed electricians and electrical contractors are the primary installers of this wire type.

TFFN wire is commonly used in residential and light commercial electrical work, including conduit runs, panel feeders to fixtures, and machine wiring where a flexible, thermoplastic nylon-jacketed conductor is specified. The 16 AWG size is a typical choice for lighting circuits and low-ampacity branch circuits. The blue jacket color supports color-coded wiring schemes and makes conductor identification straightforward in multi-wire installations.

Key Features

• 16 AWG fully annealed bare copper conductor with 26-strand configuration for flexibility
• PVC insulation with nylon jacket per TFFN designation
• 600-volt rating suitable for standard branch circuit applications
• 90 degrees C dry temperature rating
• 500-foot spool reduces splice frequency on longer runs
• Blue jacket supports color-coded wiring identification

Compatibility

Designed as a general-purpose TFFN-type stranded building wire for use in dry conduit runs and fixture wiring applications where 16 AWG, 600-volt conductors are specified.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits at the breaker panel and verify with a meter before handling conductors. TFFN wire is rated for dry locations only and must be routed through appropriate conduit per NEC requirements. Do not exceed the conductor ampacity ratings defined by the NEC for 16 AWG wire in the applicable installation method.
