Ancor Red/Yellow 18/2 AWG Flat Safety Duplex Cable 500-Foot

The Ancor Red/Yellow 18/2 AWG Flat Safety Duplex Cable is a 500-foot spool in a white common jacket, with Type 3 Class K stranding.

This is the ABYC-coded version of the lightest duplex, using yellow negative rather than black. Even on signal-level circuits the convention is worth following consistently, because a technician tracing a fault years later reads colors before anything else.

Eighteen gauge suits indicator lights, sensors, control signals and low-draw electronics rather than anything carrying real current. Its limitation is voltage drop over distance, so a long 18 gauge run to a device drawing a couple of amps will misbehave rather than fail outright.

A 500-foot spool is a large quantity of a wire used in short lengths, appropriate for an instrument or control rewire. The white common jacket identifies the cable as safety-coded from outside, and Type 3 Class K stranding resists corrosion, vibration and flexing fatigue. Explore more duplex and triplex cable.
