#4-3C Tray Cable With Ground — 200ft
The 200-foot version of the #4-3C tray cable with ground is designed for mid-length runs in tray systems. It features a 4 AWG size, three conductors, and a 7/.0772 strand count for flexible handling and reliable current capacity. The ground conductor provides a protective return path, meeting common electrical code requirements for exposed tray installations. This option is well-suited for service feeders and branch circuits in commercial spaces where space and durability matter. Consider pairing with standard tray fittings for efficient routing across cabinets or ceiling spaces.
#4-3C Tray Cable With Ground — 100ft
The 100-foot variant provides a compact option for shorter runs or initial installations. It maintains the same 4 AWG conductor size and a trio of conductors with a dedicated ground. The 7/.0772 strand arrangement supports reasonable flexibility for routing inside trays or across utility corridors. This length is advantageous in retrofit jobs or projects with strict space constraints, ensuring consistent electrical performance with minimal splicing requirements.
#4-3C Tray Cable With Ground — 350ft
The 350-foot option balances length and manageability for larger installations. With 4 AWG conductors and three conductors plus ground, this cable is suitable for feeders or distribution runs within cable trays. The strand count of 7/.0772 supports good flexibility without sacrificing current capacity. Use in applications requiring longer spans between junctions, while maintaining uniform voltage delivery across connected equipment.
#4/0-3C Tray Cable With Ground — 450ft
This 450-foot variant uses a larger 4/0 AWG conductor for higher current capability, suitable for heavy feeders in large installations. Three conductors plus a ground deliver robust power paths across long tray runs. The 19/.1055 strand count enhances flexibility for intricate tray routing while preserving mechanical strength. Ensure compatibility with panel feeders and distribution blocks when sizing for the expected load and temperature ratings.
#8-3C Tray Cable With Ground — 750ft
The 750-foot version uses smaller 8 AWG conductors, still delivering three conductors plus ground. This length is well-suited for expansive tray layouts or multi-panel installations where long uninterrupted runs reduce the need for splices. The 7/.0486 strand arrangement simplifies bending and routing through trays and supports consistent impedance along the run. Ideal for light to medium-load distribution lines within warehouses or manufacturing floors.
Buying Guide
Key purchase considerations help determine the best 4/3C THHN-PVC tray cable with ground for a project. First, verify conductor size and current requirements. Larger AWG sizes (such as 4/0 or 8) suit higher loads or longer runs, while smaller sizes fit lighter loads or tighter spaces. Second, confirm the presence of a ground conductor for safety and code compliance in tray applications. Third, assess the length needed to minimize splices and inventory complexity; longer runs reduce joint points but may require careful handling and bending radii.
Material and construction impact performance. PVC jackets offer moisture resistance and flame retardance, but ambient temperature ratings and tray exposure should guide derating and insulation choices. Stranding affects flexibility; finer strands improve bendability but can be prone to damage if mishandled. In addition, ensure compatibility with local electrical codes, especially in commercial spaces with stringent safety requirements. Finally, consider supplier reliability and product documentation, including certificates and test data, to support inspections and warranty considerations.
From a procurement perspective, balance cost with electrical capacity and installation practicality. Shorter lengths reduce waste and storage needs, but may require more splicing points. Longer cables enable fewer connections but may complicate handling. For project planning, map run routes within trays, anticipate future expansion, and confirm connector and termination compatibility with existing equipment. A comprehensive approach helps ensure long-term reliability, safety, and compliance across diverse installations.
