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

The Ancor Round Instrument Cable – 20/3 AWG – Red/Black/Bare – 100' is a marine-grade electrical cable engineered to meet the electrical demands of instrumentation systems on vessels of all sizes. Built to exceed UL 1426, ABYC, and US Coast Guard Charter boat (CFR Title 46) standards, this cable combines durability with reliable signal transmission in harsh marine environments where standard electrical wire fails.

The 20/3 AWG construction provides three individual conductors rated at 600V with premium vinyl insulation that maintains flexibility at temperatures as low as –40°F and resists salt water, battery acid, oil, gasoline, heat, abrasion, and ultraviolet radiation. The combination of red, black, and bare copper conductors allows for power distribution and ground returns across instrument panels, navigation systems, and onboard electronics. The 100-foot length accommodates wiring runs on boats from 25 to 50+ feet without requiring multiple splices, reducing potential failure points in critical electrical circuits.

This cable is designed for weekend fishermen running basic fish finders and depth sounders as well as serious offshore anglers with complex integrated electronics including GPS plotters, radar, autopilot systems, and redundant instrumentation. Saltwater exposure degrades inferior wiring within months; Ancor's marine-specific formulation resists corrosion far longer than automotive or general-purpose cables. Proper gauge selection (20 AWG) ensures voltage drop remains minimal over extended runs while avoiding oversizing that wastes installation space and adds unnecessary weight to a vessel.

Ancor's commitment to ABYC and Coast Guard compliance standards reflects the brand's position as a manufacturer trusted by marine surveyors and professional boat builders. Whether upgrading original equipment, extending existing circuits, or building out a new wiring harness, the 100-foot spool provides sufficient material for most vessel installations while the multi-conductor configuration reduces the number of individual cable runs required during retrofit projects.
