STOW Marine Cable Technology

This cordset features Type STOW marine cable, specifically engineered for the demanding marine environment:

? Advanced Insulation System

EPDM Insulation: Ethylene Propylene Diene Monomer provides superior resistance to ozone, weather, and chemical exposure common in marine applications.

?️ Marine-Grade Jacket

CPE Construction: Chlorinated Polyethylene jacket offers exceptional toughness against abrasion, saltwater, and UV exposure.

⚡ Optimal Conductivity

#6 AWG Copper: Heavy-duty copper conductors minimize voltage drop over the 50-foot length while maintaining full amperage capacity.

? Marine Environment Rated

Harsh Condition Performance: STOW cable is specifically designed to withstand the toughest marine elements including temperature extremes and moisture exposure.

IP56 Waterproof Protection System

The boat-side connector features IP56 ingress protection rating, providing robust defense against marine environmental hazards:

IP5X - Dust Protection

  • Limited dust ingress permitted
  • Prevents harmful dust accumulation
  • Maintains electrical integrity in dusty conditions
  • Suitable for marina and boatyard environments

IPX6 - Water Protection

  • Protects against high-pressure water jets
  • Withstands 100 liters per minute at 100 kPa pressure
  • Resistant to heavy rain and spray conditions
  • Tested at 3-meter distance for 3+ minutes

Advanced Sealing Technology

The metallic threaded sealing ring creates a watertight interface between the cordset connector and vessel inlet, preventing water ingress that could cause electrical faults or safety hazards.

Extended Reach Applications

The 50-foot length provides solutions for challenging docking situations where standard cordsets are inadequate:

?️ Wide Slip Configurations

Perfect for wide slips where power pedestals are located at significant distances from the vessel's shore power inlet, common in mega-yacht and commercial vessel facilities.

⛵ Mediterranean Mooring

Ideal for stern-to or Mediterranean-style mooring where vessels anchor out and tie stern lines to shore, requiring extended reach to shoreside power connections.

? Marina Service Areas

Essential for service docks and boatyards where vessels may be positioned at various distances from power sources during maintenance or repairs.

? Multi-Hull Vessels

Accommodates catamarans and trimarans with wide beams where the shore power inlet may be located far from the dock edge due to vessel configuration.

Professional-Grade Construction Features

? Metallic Threaded Sealing Ring

Creates a positive, watertight seal when connected to the vessel inlet, preventing water ingress and electrical faults. The threaded design ensures consistent, reliable connections.

? Factory Pre-Wired Assembly

Completely pre-wired with molded-on devices eliminates field wiring errors and ensures consistent, professional connections. Factory assembly guarantees optimal electrical integrity.

? Bull Ring Strain Relief

Integrated bull ring design provides superior strain relief on terminals, preventing conductor fatigue and maintaining electrical connections under repeated flexing.

? Copper Crimp Barrel Terminations

Professional-grade copper crimp barrels provide more reliable connections than screw terminals, with lower resistance and greater longevity in marine environments.

? Molded Flex Control

Molded-in flex feature controls cord entry angle and prevents water ingress at the critical junction between cable and connector.

✨ Corrosion-Resistant Materials

Nickel-plated brass contact blades and shell provide superior corrosion resistance and positive electrical connections in saltwater environments.

Installation & Usage Considerations

Cable Management

The 50-foot length requires proper cable management to prevent damage and ensure safety:

  • Use cable organizers or hooks to keep excess cable off the dock
  • Avoid sharp bends or kinks that could damage internal conductors
  • Ensure proper strain relief at both connections
  • Route cable to avoid foot traffic and equipment areas
  • Consider using cable protectors in high-traffic areas

Voltage Drop Considerations

Extended length requires attention to voltage drop characteristics:

  • #6 AWG conductors minimize voltage drop over 50-foot length
  • Monitor voltage at vessel's electrical panel during high load conditions
  • Consider load balancing for 125/250V split-phase applications
  • Verify proper voltage levels for sensitive electronic equipment

⚠️ Extended Length Safety Requirements

ABYC Compliance

Ensure extended length installations meet ABYC E-11 requirements for voltage drop and circuit protection.

ELCI Protection

Equipment Leakage Circuit Interrupter protection is critical for longer cordsets to detect ground faults.

Regular Inspection

Increased length means more exposure - inspect entire length regularly for damage or wear.

Frequently Asked Questions

Why choose a 50-foot cordset over a standard 25-foot version?

The 50-foot length provides twice the reach of standard cordsets, essential for wide slips, distant pedestals, Mediterranean mooring situations, and large multi-hull vessels. It eliminates the need for extension cords which can create safety hazards and voltage drop issues.

Does the extended length affect power delivery?

The #6 AWG STOW cable is sized to minimize voltage drop over the 50-foot length. While there will be slightly more voltage drop than a 25-foot cord, it remains within acceptable limits for marine applications when properly sized for the load.

What is Type STOW cable and why is it used?

STOW cable features EPDM insulation and CPE jacket specifically designed for marine environments. This construction provides superior resistance to ozone, weather, saltwater, and physical abuse compared to standard cable types, ensuring long-term reliability in harsh marine conditions.

Is IP56 rating sufficient for marine use?

IP56 provides protection against high-pressure water jets and limited dust ingress. While higher ratings like IP67 offer better protection, IP56 combined with the metallic threaded sealing ring and proper installation provides adequate protection for most marine applications when the connector is properly mated.

How should I manage and store this 50-foot cordset?

Use proper cable management techniques including dock hooks or organizers to keep excess cable off the ground. Store in large, loose coils to prevent kinking. Consider a dedicated storage reel or bag designed for marine shore power cables to extend service life.

Can I use this cordset for both 125V and 250V applications?

Yes, this cordset supports both 125V (single-phase) and 250V (split-phase) applications. The 3-pole 4-wire grounding configuration provides two hot legs (L1, L2), neutral, and ground, allowing flexible power distribution based on your vessel's electrical panel configuration.

Extended Length Advantages

✅ Eliminates Extension Cords

No need for potentially dangerous extension cord connections that can create water ingress points and increase resistance

✅ Single Connection Point

Direct vessel-to-shore connection reduces potential failure points and maintains electrical integrity

✅ Professional Installation

Factory-assembled construction ensures consistent quality and eliminates field wiring errors

✅ Flexible Positioning

Extended reach allows optimal vessel positioning without being constrained by power pedestal location

Technical Compliance & Standards

✓ UL Listed Meets Underwriters Laboratories safety standards
✓ Marine Rated Designed specifically for marine environmental conditions
✓ ABYC Compatible Suitable for ABYC E-11 compliant installations

Professional Installation: While this cordset is designed for reliable plug-and-play operation, ensure your vessel's electrical system meets ABYC E-11 standards and includes proper ELCI protection. Consult with qualified marine electricians for complex installations.
