marine duplex wire

Marine duplex wire refers to a type of marine-grade electrical wire that consists of two individually insulated conductors within a single cable.  It is commonly used for low-voltage electrical wiring applications in marine environments.

Here are some key features and characteristics of marine duplex wire:
1.  Construction: Marine duplex wire typically consists of two stranded copper conductors that are individually insulated with a durable and moisture-resistant material, such as PVC (Polyvinyl Chloride) or Tinned Copper.  The two insulated conductors are then paired together within a single outer jacket.
2.  Size and Gauge: Marine duplex wire is available in various sizes and gauges to accommodate different electrical requirements.  The wire size is usually specified by its American Wire Gauge (AWG) rating, which indicates the diameter of the wire.  Common sizes for marine duplex wire range from 10 AWG to 18 AWG, with larger gauges indicating thicker wire diameters.
3.  Voltage Rating: Marine duplex wire is typically designed for low-voltage applications, such as 12V or 24V systems commonly found in boats and yachts.  The voltage rating of the wire should match the voltage requirements of the specific electrical circuits it will be used for.
4.  Insulation and Jacketing: The individual conductors in marine duplex wire are insulated to provide electrical insulation and protection against moisture, chemicals, and abrasion.  The outer jacket of the wire provides additional protection and durability.
5.  Marine-grade Properties: Marine duplex wire is specifically designed to withstand the harsh marine environment.  It is typically resistant to water, oil, fuel, UV radiation, and other corrosive elements commonly found in marine environments.  The wire's insulation and jacketing materials are chosen to provide excellent resistance to moisture and corrosion.

Marine duplex wire is commonly used for various electrical applications on boats and yachts, including lighting, navigation systems, instrument panels, and other low-voltage circuits.  It is important to select marine-grade wire that meets the relevant industry standards, such as ABYC (American Boat and Yacht Council) or UL (Underwriters Laboratories), to ensure its safety and reliability in marine applications.

Proper installation, routing, and securing of marine duplex wire are essential to maintain its integrity and prevent damage.  It is recommended to consult with a qualified marine electrician or technician for any wiring installations or modifications on your boat or yacht to ensure compliance with safety standards and regulations.
