Ancor Round Instrument Cable - 20/3 AWG - Red/Black/Bare - 100'

The Ancor Round Instrument Cable – 20/3 AWG – Red/Black/Bare – 100' is the marine electrician's go-to choice for instrument panel wiring and gauge connections aboard recreational and commercial vessels. Built to withstand the harsh saltwater environment, this cable delivers reliable signal transmission from your helm gauges, depth finders, and engine instrumentation back to their respective displays.

Whether you're running new gauges on a restoration project or replacing corroded wiring in an aging console, this Ancor cable meets the exacting standards that professional boat builders and serious DIY boaters demand. The 20/3 AWG construction—three 20-gauge conductors—provides the gauge and flexibility needed for instrument circuits while remaining compact enough to route through tight helm installations without kinking or binding.

Ancor's marine-grade PVC jacket resists UV degradation, oil, and moisture that corrode standard electrical wire within months on the water. The color-coded conductors (red, black, and bare) eliminate guesswork during installation and troubleshooting, reducing the risk of reversed polarity or crossed signals that damage sensitive electronics. The 100-foot spool length covers most single-vessel wiring projects with room to spare, minimizing joint splices that introduce failure points in critical gauge circuits.
