8 AWG 3C Shielded VFD Cable W/ 3 #14 Grounds

"8/3 Shielded VFD Cable W/ 3 #14 Grounds is a heavy-duty, 600V TC-ER / 1000V Flexible Motor Supply rated cable engineered for Variable Frequency Drive systems. Constructed with three 8 AWG stranded tinned copper conductors, XLPE insulation, dual-layer EMI shielding (100% aluminum/Mylar/aluminum tape plus tinned copper braid), and three #14 AWG grounds, this cable provides reliable motor power and noise suppression. Its rugged, direct-burial rated PVC outer jacket resists sunlight, moisture, oil, and abrasion across temperatures ranging from -40°C to 90°C."

Key Features & Benefits: 8/3 Shielded VFD Cable W/ 3 #14 Grounds

Standard power cable breaks down rapidly under PWM voltage spikes and floods adjacent control systems with severe noise. This specialized 3-conductor VFD cable solves these jobsite failures:

• Dual-Layer EMI/RFI Shielding: Combines a 100% coverage aluminum/Mylar/aluminum tape shield with a tinned copper braid to trap high-frequency noise and protect nearby sensors or PLCs.

• 3 Symmetrical #14 AWG Grounds: Features three stranded tinned copper grounds evenly distributed to balance magnetic fields and provide a low-impedance path for stray currents.

• Exposed Run (TC-ER) Rated: Complies with UL 1277 for continuous installation out of cable trays to the motor without rigid metal conduit.

• Heavy-Duty Industrial Jacket: Sunlight, oil, moisture, and abrasion resistant black PVC jacket approved for direct burial in wet or dry environments (-40°C to 90°C).

• Simplified Landing & Termination: The 3-conductor layout with symmetrical grounds simplifies wire routing into cramped VFD enclosures, reducing installation time and overall labor costs.

Common 8/3 VFD Cable Applications

• Industrial Conveyors & Pumps: Delivering clean power to 8 AWG 3-phase motor loads while blocking EMI from reaching nearby control panels.

• HVAC & Chiller Drives: Powering variable speed supply fans, roof-top units, and industrial pumping systems.

• Process Machinery Interconnects: Interconnecting heavy processing equipment in station trays with streamlined termination.

• Outdoor & Wash-Down Drives: Powering variable-speed drives in wet, direct burial, or outdoor environments where oil and UV resistance are required.

Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes.

• Industrial Conveyors & Material Handling Systems: Delivers reliable power to 8 AWG motor loads across automated distribution centers, sorting lines, and material handling plants. Dual-layer shielding (100% aluminum tape + tinned copper braid) prevents VFD noise from interrupting optical sensors and PLC logic.
• Commercial & Industrial HVAC Systems: Powers high-horsepower variable frequency drive fan motors, chillers, and large cooling towers. Engineered with high-dielectric XLPE insulation, it absorbs destructive reflected wave voltage spikes to protect motor windings from insulation breakdown.
• Municipal Water Treatment & Pumping Stations: Ideal for variable-speed booster pumps, blowers, and sludge processing equipment. Its heavy-duty PVC jacket is oil-, moisture-, and chemical-resistant, making it suitable for direct-burial runs between control buildings and outdoor drive motors.
• Factory Automated Machinery & Robotics: Handles high-frequency switching environments in automated machinery, machine tools, and stationary tray interconnects. The 133-strand tinned copper construction provides flexibility for smooth pulls through tight cable trays and raceways.
• Harsh Wash-Down & Outdoor Industrial Facilities: Built for food processing plants, chemical facilities, and outdoor industrial sites. Rated for wet/dry operation from -40°C to 90°C with full UV and sunlight resistance, holding up under high-pressure equipment wash-downs.
