The heavy gauge electrical boat marine wiring is designed with a thick protective outer insulation coating makes it perfect for heavy-duty marine and other harsh external outdoor wiring projects

Multi Use: the 14 gauge marine wire use in pontoon boat/bass boat/boat trailer/ fish finder/truck/RV/Van/ATV trailer electrical system:wiring light (spotlight,underwater light,flood light, navigation lights,headlight), solar inverters, shore power,bilge pump,extend new bank charger leads, speaker wire,electric brake wires, radio stereo, alarm etc

Type THHN; themoplastic insulation; high heat resistant; nylon jacket single conductor wire

Abrasion; moisture; gasoline; and oil resistant jacket

Annealed (soft); compressed stranded; copper conductor

☞Feature: 132 strands 0.295 mm tinned copper wire are inside each cable. Compared with aluminum materials, it has lower resistance and higher conductivity. Exclusive insulation is rated at 600 volts, 221°F / 105°C dry and 167°F / 75°C wet

☞10 Gauge Marine Wire: Positive (Red) and negative (Black) 2 Core marine wire. Black & red jackets allow for easy identification of polarity, Prevents potential mispolarity issues that could result in damage to PV equipment. External pvc jacket color is white cable lining.

☞Waterproof and Anti-Corrosion: Thick pvc jacket of wire is waterproof. We use thick gauge tinned copper wire to protect from salt and rusting due to high salt content on deep sea trips. Insulation resists salt water, battery acid, oil, gasoline, heat, abrasion, and UV resistant radiation

Branch, feeder and service power distribution in commercial, industrial, institutional and multi-residential buildings
