New 10/2 Awg Marine Duplex Cable 100Ft Tinned Copper 2-Conductor Red Black Gray Jacket Compatible

UNIVERSAL MARINE WIRE — 10/2 AWG ROUND DUPLEX GRAY JACKET BOAT CABLE 100 FT SPOOL:

GRAY-JACKETED MARINE CABLE — OEM SPEC AND DIFFERENTIATION APPLICATIONS:
This is the gray-jacketed variant of Cobra's standard 10/2 marine duplex cable. The gray outer jacket provides circuit differentiation from standard white-jacketed DC cables and matches OEM boat builder harness color specifications on certain vessels. Internal conductors meet SAE J1128 / ABYC E-11 with traditional red positive + black DC negative color coding.

CABLE CONFIGURATION:
• 2 Conductors x 10 AWG Each (Red + Black per SAE J1128 / ABYC E-11)
• GRAY Round Outer PVC Jacket — Differentiation From Standard White Marine Cable
• Class K Type 3 Tinned-Copper Stranding (Type III, Finely Stranded)
• 600V Voltage Rating
• 105°C Dry / 75°C Wet Temperature Rating
• UL Listed BC-5W2 Boat Cable per UL 1426
• 100 Foot Spool

WHY CHOOSE GRAY JACKET vs STANDARD WHITE:
• OEM Boat Builder Harness Color Match (Specific Vessels Use Gray)
• Circuit Differentiation in Installations With Multiple Cable Types
• Industrial and Commercial Marine Applications Where Gray is Preferred
• Visible Cable Run Aesthetics — Gray Often Desired for Visible Installations
• Match Existing Harness Color for Repair and Extension Work
• Differentiation From Standard White DC Cable in Engine Rooms / Service Areas

INTERCHANGE: ROUND vs FLAT GRAY 10/2 OPTIONS:
• COB-B6G10T-21 (THIS ITEM) — ROUND profile gray cable
• COB-B7G10T-21 — FLAT profile gray cable (alternative profile, same conductors)
Both provide identical electrical specs — round preferred for conduit/loom routing, flat preferred for behind-panel installation.

ABYC E-11 DC COLOR CODE — RED + BLACK INNER CONDUCTORS:
Inner conductors follow ABYC E-11 / SAE J1128 standards:
• RED = Positive 12V Ungrounded Conductor
• BLACK = Traditional DC Negative / Ground Return Conductor
Black remains acceptable per current ABYC standards (yellow has been preferred since the 2008 revision for new construction).

WHEN TO USE 10/2 — MEDIUM-CURRENT DC APPLICATIONS (~30-40A):
• 16/2 / 14/2 / 12/2 = lighter gauge for accessory branches
• 10/2 THIS ITEM (~30-40A) = MEDIUM-CURRENT distribution feeds, smaller inverters
• 8/2 (~80A) = high-current main feeds, larger inverters

COMMON 10/2 GRAY JACKET MARINE APPLICATIONS:
• OEM Boat Builder Cable Replacement (Vessels Originally Wired with Gray)
• Distribution Panel Feeds Where Gray Cable is Specified
• Larger Bilge Pump Dedicated Runs (1500-2000+ GPH Pumps)
• Macerator Pump Dedicated Power Cable
• Smaller Windlass / Anchor Winch Power Cable
• Trolling Motor Dedicated Run (12V Medium-Power Systems)
• Inverter Input Cable (500-1000W Marine Inverters)
• Battery Charger Output (10-30A Smart Chargers)
• Solar Charge Controller Output (Medium Solar Arrays)
• Marine Refrigerator Dedicated Feed (Medium Units)
• Subpanel Feed in Mid-Size Vessels
• Engine Compartment to Switch Panel Runs (Visible Installations)
• Industrial Marine Equipment Power Cables
• Commercial Vessel DC Distribution
• Engine Room Service Wiring (Differentiated from White Standard Cable)
• Stereo Amplifier Dedicated Power (300-500W)
• Cabin Heater Power Cable (Smaller Units)
• Trim Tab Pump Dedicated Power
• Marine Air Conditioning DC Feed (Smaller Units)
• Dual Battery Bank Distribution

NOT RECOMMENDED FOR (USE LARGER GAUGE OR DIFFERENT CABLE):
• Main Battery Cables — Use Heavy Gauge Single-Conductor (8, 4, 2, 1/0 AWG)
• Engine Starter Wiring — Use Heavy Gauge Single-Conductor
• Large Inverters (1500W+) — Use 8/2 or Larger Cable
• Large Bow Thrusters — Use 8 AWG, 4 AWG, or 2 AWG Single-Conductor
• High-Current Loads Above ~40 Amps Continuous — Step Up to 8/2
• AC Circuits — Use AC Triplex Cable (Black/White/Green)
• Bonding/Safety Ground — Use Single-Conductor Green Wire

COMPATIBLE VESSEL TYPES:

• OEM Boats Originally Wired with Gray-Jacketed Cable
• Industrial and Commercial Marine Vessels
• Sterndrive and Inboard Engine Compartment DC Distribution
• RV and Trailer Marine-Grade Medium-Current Wiring

STANDARDS COMPLIANCE:
• UL Listed UL 1426 Boat Cable Standard
• UL Listed BC-5W2 Boat Cable Classification
• ABYC E-11 Compliant (American Boat & Yacht Council)
• Inner conductors meet SAE J1128
• United States Coast Guard (USCG) Approved
• Made in USA

FITMENT NOTE:
Universal multi-conductor round duplex marine cable with GRAY jacket — fits any marine application requiring 10/2 AWG paired DC conductors with gray outer jacket for OEM spec match or circuit differentiation. Not vehicle-specific. Per ABYC E-11, red is positive 12V and black is the traditional DC negative. Inner conductors are identical to standard white-jacketed cable — only the outer jacket color differs. For flat profile use COB-B7G10T-21 (alternative). For standard white jacket use B6W/B7W series. For higher current step up to 8/2; for branch circuits step down to 12/2 or 14/2.
