Southwire 946050518 16 Awg Copper Hook-up Wire 500 Ft

Product Description

The SOUTHWIRE 946050518 is a 16 AWG stranded copper hook-up wire designed for low-voltage control and signal wiring applications in residential and commercial systems. Built with 26 strands of copper for flexibility, the wire features a clear white PVC jacket with a brown color indicator and measures 0.23 inches in outside diameter. Rated for operating temperatures from -4 degrees F to 140 degrees F, this wire meets UL Type CL3 and NEC Article 725 standards, making it suitable for Class 3 remote-control and signal circuits. It is sold in 1-foot increments with a 250-foot minimum cut length from a 500-foot total coil. Electricians and low-voltage control technicians will find this wire well-suited for panel wiring, thermostat circuits, and control system runs.

This hook-up wire is used in a wide range of low-voltage control wiring applications including HVAC control boards, security systems, audio and video signal runs, and automation wiring. Its flexible 26-strand construction makes it easier to route through conduit or tight enclosures compared to solid conductor wire. The PVC jacket provides resistance to common shop and field contaminants. It is appropriate for both new installations and service replacement wiring where Class 3 circuit compliance is required.
