Ancor 131710 Triplex Cable 16/3 AWG Flat - Marine Grade, 100ft

In this review the Ancor 131710 Triplex Cable is evaluated for marine wiring tasks where corrosion resistance and flexibility matter most. The reviewer finds it ideal for boaters and marine electricians who need a flat, three-conductor run of 16/3 (3 x 1mm2) wire in a 100ft length; the single biggest reason to buy is its tinned copper stranding, which markedly reduces corrosion and electrolysis risk in saltwater environments while remaining ultra flexible for routing in tight spaces.

Key Features

• Tinned copper stranding: Provides superior corrosion protection and easier soldering for long-lasting connections in marine conditions.
• Ultra flexible stranding: Resists fatigue from vibration and frequent flexing, making it simple to run around bulkheads and through conduits.
• Premium vinyl insulation: Rated for 600 V and stays flexible in extreme cold, which helps maintain integrity from -40 DegreesF/C to hot engine spaces.
• Chemical and UV resistance: The insulation resists salt water, battery acid, oil, gasoline and ultraviolet exposure for longevity on deck.
• Flat triplex form: Three conductors in a flat assembly keep runs neat and simplify mounting under trim or along hull surfaces.

Who It's For

Boat owners, marine electricians, and DIYers who install shore power circuits, lighting feeds, accessory runs or instrument wiring will appreciate this cable's combination of flexibility and corrosion resistance. Its flat, three-conductor layout suits low-voltage DC applications aboard small craft and sport boats where routing in confined spaces is required.

Those needing heavier gauge primary power feeds, higher voltage shore power wiring, or individual insulated conductors for complex control panels should look elsewhere; this product is designed for 16/3 marine-grade DC or accessory circuits rather than heavy AC or high-current battery main feeds.

Pros & Cons

Pros

• Excellent corrosion protection from tinned copper, suitable for saltwater exposure.
• Very flexible Type 3 stranding makes routing and soldering terminals straightforward.
• Durable vinyl insulation resists heat, oil and UV for extended service life.

Cons

• Length reports are mostly accurate, but a few customers noted up to 1 ft variance in delivered length.
