Aluminum Generator Cable, 1-3C w/ Ground + 18/9C, 100 Amps, 17kW-24kW, 600V

1 AWG 3-Conductor Aluminum Generator Cable with Ground and 18 AWG 9-Conductor Control Bundle is a specialized, all-in-one power and intelligence composite cable engineered for standby home generators and light commercial backup systems. Designed to streamline complex multi-conduit runs into a single pulling operation, this dual-rated line is optimized to support 17kW to 24kW generator units, supplying up to 100 Amps of continuous emergency load capacity under a maximum 600V operating threshold.

This heavy-duty hybrid asset combines raw electrical power distribution with low-voltage system logic inside a rugged, sunlight-resistant, direct-burial polyvinyl chloride (PVC) outer jacket. The power core features three robust 1 AWG compact-stranded aluminum conductors accompanied by an insulated aluminum ground. Nestled alongside this main power run is a built-in 18 AWG 9-conductor control cable wiring harness, providing the necessary paths for automated utility sensing, battery charging, and generator command intelligence without requiring a separate layout pipe.

ELECTRICAL AMPACITY & GENERATOR RUN RATINGS

Engineered to match the high-demand continuous loads of automated emergency standby equipment, this composite cable features distinct power limits based on insulation parameters and structural cooling boundaries:

• Maximum Current Capacity (75°C Terminations): 100 AMPS

  This rating complies with National Electrical Code (NEC) Article 310 parameters for Type THHN/THWN-2 aluminum conductors terminated into standard 75°C equipment lugs.

• Power Output Handling Range: 17 kW to 24 kW

  Optimized explicitly for single-phase 240V residential generator applications, providing safe mechanical and thermal headroom during cold starts and sudden utility transfer load spikes.

Key Features

• All-In-One Unified Design: Combines heavy aluminum power conductors and a multi-conductor copper control bundle within a single outer jacket, slashing trench labor, minimizing conduit jam scenarios, and eliminating multiple pipe runs.

• Compact-Stranded AA-8000 Aluminum Alloy: Power conductors are extruded using advanced AA-8000 series aluminum alloy, providing excellent flexibility, reduced cable weight, and highly reliable connections at standard equipment lugs.

• Integrated 18/9C Copper Control Core: Features a dedicated 9-conductor, 18 AWG copper signaling bundle that provides smooth transmission for automated automatic transfer switch (ATS) communication, smart digital monitoring, oil pressure sensors, and float chargers.

• Dual-Rated THHN / THWN-2 Elements: Internal power lines are insulated with tough polyvinyl chloride (PVC) and topped with a slick nylon armor skin, rated for dry environments up to 90°C and wet subterranean environments up to 75°C.

• Direct-Burial Outer Armor Jacket: Protected by an industrial-grade, sunlight-resistant, moisture-impervious PVC outer shield. This jacket allows the cable to be run inside standard PVC conduit, heavy metal raceways, or laid directly into open underground trenches where code permits.

Common Applications

• Automated Standby Generator Connections: Linking 17kW through 24kW residential and light industrial generators safely to their respective Automatic Transfer Switches (ATS).

• Whole-House Backup Infrastructure: Running high-amperage backup links for estate homes, rural agricultural facilities, and critical municipal pump sites.

• Multi-Zone ATS Communication Paths: Providing the unified power feed and remote-start signaling circuit between isolated generator docks and internal building sub-panels.

Technical Note: To prevent localized oxidation and terminal failures over time, all aluminum-to-copper transitions or connections at the generator terminal blocks must be coated with a certified anti-oxidant joint compound (such as Noalox or Penetrox). Tighten all mechanical terminal lugs strictly to the manufacturer's specified inch-pounds of torque using a calibrated torque wrench.

DISCLAIMER: The technical information provided is for general reference only. Emergency standby generator systems and automatic utility transfer switches must strictly adhere to NFPA 70 (National Electrical Code), local utility company parameters, and the specific manufacturer’s wiring schematics. Always cross-reference the official engineering data sheet and local structural code books prior to pulling cable lengths or finalizing backup power hookups.

⚠️ The applications listed below are for informational and educational purposes only. Electrical code requirements vary significantly by region. Always consult a licensed electrician and your local building authority to verify compliance with the National Electrical Code (NEC®) for your specific project before purchasing or installing cable.

Common 1-3C w/ Ground + 18/9C Generator Cable Use Cases

• Standby Generator Power Integration: Functions as the primary all-in-one feeder cable connecting mid-to-large tier residential standby generators (rated 17kW to 24kW) directly to automatic transfer switches (ATS).
• Unified Control & Power Routing: Groups the 1 AWG aluminum power conductors and an 18 AWG 9-conductor control wiring harness under a single outer jacket, removing the need to fish separate control lines for battery chargers, digital control panels, and utility voltage sensing.
• 100-Amp Whole-Home Backup: Routes a continuous 100 Amps of 600V power to handle standard whole-house emergency loads, keeping central AC units, refrigerator networks, lighting grids, and water pumps operational during blackouts.
• Trench and Conduit Pulls: Engineered with a durable, low-friction jacket designed for efficient pulling through underground Schedule 40 or Schedule 80 PVC conduit from an outdoor generator pad into a residential basement or garage.
• Small Business Emergency Power: Deployed in light commercial settings, remote offices, and retail storage facilities to safeguard critical point-of-sale systems, refrigeration units, and security networks against grid failures.
