Generator Cable, 1/3C w/ Ground + 18/9C, 130 Amps, 28kW, 600V

1/3C + 18/9C w/ Ground Generator Cable (TC-ER-JP) is a high-capacity, multi-conductor composite power and control tray cable specifically engineered for heavy-duty whole-house and light commercial standby generator installations rated up to 28kW.

Instead of routing multiple bulky feeders and control wires through rigid conduits, this integrated cable combines the 130 Amp power supply lines, the ground conductor, and 9 control/sensing wires into a single, compact, and durable outer jacket.

ELECTRICAL AMPACITY & RATING

• Current Rating: 130 AMPS (based on 75°C terminal temperature rating parameters per NEC rules).

• Generator Compatibility: Engineered for 28kW standby generator systems (such as Generac, Kohler, Cummins, and Briggs & Stratton).

• Voltage Rating: 600 Volts maximum.

Key Features

• All-in-One Composite Construction: Integrates heavy 1 AWG main power conductors, an insulated ground line, and 9 dedicated control wires under one heavy-duty sheath, saving hours of pull labor.

• Type TC-ER-JP Listed: Approved as Tray Cable - Exposed Run with Joist Pull (JP) certification, allowing open runs through residential floor joists and wall framing without needing continuous conduit runs (per NEC Article 336).

• Direct Burial & Weather Protection: Extruded with a heavy, sunlight-resistant (SUN RES) PVC jacket engineered for direct earth burial, open cable trays, or interior structural framing.

• Industrial Resistance: Rated for severe cold-bend installations (-40°C) and fully compliant with FT4 / IEEE vertical flame tests.

Cable Layer Architecture (From Core to Outer Sheath)

1. Power Conductors (3 x 1 AWG): Stranded bare copper cores insulated with THHN/THWN-2 (PVC/Nylon) for delivering 240V multi-phase generator output straight to the Automatic Transfer Switch (ATS).

2. Ground Conductor (1 x 6 AWG): Stranded bare copper grounding wire (typically insulated green) for full equipment bonding.

3. Control/Sensing Conductors (9 x 18 AWG): Stranded copper control wires utilized for utility voltage sensing, 24V signal relays, battery trickling, exercise clock circuits, and generator status indicators.

4. Core Fillers & Binder: Non-hygroscopic polypropylene fillers with mylar core wrap to ensure roundness and mechanical stability during tight pulls.

5. Outer Jacket: Heavy-duty, UV- and moisture-resistant Black or Orange PVC outer jacket.

Technical Specifications

• Power Conductor Size: 1 AWG Stranded Copper (3 Conductors)

• Ground Conductor Size: 6 AWG Stranded Copper (1 Conductor)

• Control Conductor Size: 18 AWG Stranded Copper (9 Conductors)

• Insulation Type: PVC with Nylon skin (THHN/THWN-2 rated)

• Jacket Material: Sunlight-resistant, direct-burial PVC

• Overall Outside Diameter: Approx. 1.25 to 1.35 inches

• Approximate Net Weight: Approx. 1,380 lbs per 1000 feet

• Temperature Limits: 90°C Dry / 75°C Wet (restricted to 75°C terminal ratings for ampacity calculations)

• Compliance Standards: UL Standard 1277 (Type TC-ER), UL 83, FT4/IEEE 1202 Flame Rated, NEC Article 336 (TC-ER-JP), RoHS Compliant

Technical Note Regarding Installation: When pulling 1 AWG composite TC-ER cable, always maintain recommended minimum bend radii (typically 8 to 12 times overall cable diameter) to prevent crushing internal control pairs. Where the cable enters panels, transfer switches, or junction boxes, use code-approved TC cable glands or strain-relief fittings to guarantee watertight seal integrity and secure mechanical retention.
