Thhncu-generic tffn18strpur500r Tffn 18 Awg Wire 500 Ft

Product Description

The THHNCU-GENERIC tffn18strpur500r is an 18 AWG stranded copper conductor wire insulated with PVC and a nylon jacket, rated TFFN type. It is designed for use in control wiring, low-voltage applications, and panel wiring where a color-coded conductor is required. The wire carries a 600-volt rating and a 90 degrees C temperature rating, making it suitable for a wide range of indoor electrical installations. It ships on a 500-foot spool, providing enough length for larger jobs or stocking in a service vehicle. Licensed electricians and electrical contractors are the primary installers of this product.

This wire is commonly used in residential and light commercial control panel wiring, motor control centers, and switchboard applications. The purple color coding supports organized, easy-to-trace wiring in multi-conductor installations. The 16-strand configuration provides flexibility during routing through conduit or around tight bends in enclosures. It is well suited for branch circuit control wiring, thermostat wiring, and other low-current signal applications where TFFN-rated wire is specified.

Key Features

• 18 AWG stranded copper conductor with 16-strand configuration for added flexibility
• PVC insulation with nylon jacket rated TFFN type for durability in conduit
• 600-volt rating supports a broad range of control and signal wiring applications
• 90 degrees C temperature rating suitable for indoor panel and conduit installations
• Purple color coding for clear conductor identification in multi-wire installations
• 500-foot spool quantity minimizes mid-job splicing and supports stocking needs

Compatibility

Designed as a general-purpose TFFN-type 18 AWG stranded control wire suitable for use in conduit, panels, and enclosures where 600-volt, 90 degrees C rated single-conductor wire is specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits before making connections and verify with a meter before handling conductors. TFFN wire is rated for use in conduit or enclosed raceways and should not be used as a direct-burial or exposed outdoor conductor unless additional protection is provided. Follow conduit fill requirements per NEC Chapter 9 when routing alongside other conductors.
