#4-3C THHN-PVC Tray Cable with Ground (100ft)
Size: 4 AWG; Number of Conductors: 3; Conductor Strand: 7/.0772. This grounded tray cable is best for moderate-length runs in trays common to commercial or industrial projects. It provides a durable insulation system suitable for indoor use where non-metallic protection is required. Best for: installers needing a ready-to-use, grounded option for compact runs in equipment racks or cable trays.
Caution: Data shows standard strand construction; verify compatibility with the specific tray and termination fittings before installation. Choose this if you need a compact yet grounded 4 AWG option for shorter runs.
#4-3C THHN-PVC Tray Cable with Ground (300ft)
Size: 4 AWG; Number of Conductors: 3; Conductor Strand: 7/.0772. This length provides flexibility for longer tray runs without splicing. Best for: projects needing extended reach within a single tray segment or plant-wide installations with consistent conductor count.
Caution: Longer pull lengths require careful protection against physical damage and proper bending radii. Choose this if you want fewer joints in a mid-size installation.
#4-3C THHN-PVC Tray Cable with Ground (450ft)
Size: 4 AWG; Number of Conductors: 3; Conductor Strand: 7/.0772. This is a long-run grounded option ideal for large facilities where minimal transitions are desired. Best for: high-capacity feeder runs in centralized equipment rooms or long cable trays.
Caution: Ensure adequate slack and protection during installation to avoid insulation damage over extended runs. Avoid excessive pulling force by using proper lubrication and aids.
#4/0-3C THHN-PVC Tray Cable with Ground (350ft)
Size: 4/0 AWG; Number of Conductors: 3; Conductor Strand: 19/.1055. This heavy-duty option supports lower voltage distribution with a thicker conductor. Best for: industrial installations requiring robust current carrying capacity over longer tray routes.
Caution: The thicker conductor may require larger terminations and connectors. Choose this if your system demands higher amperage in a grounded tray cable.
#4/0-3C THHN-PVC Tray Cable with Ground (450ft)
Size: 4/0 AWG; Number of Conductors: 3; Conductor Strand: 19/.1055. This option balances high current capability with length, making it suitable for larger installations or runs through multiple trays. Best for: facilities needing a single high-capacity grounded run across a substantial distance.
Caution: Ensure that the tray and pathway can accommodate the weight and bend requirements of 4/0 conductors. Consider staged pulling if needed.
Buying Guide
- Grounded vs No Ground: All shown options include a ground conductor. Grounded cables improve fault protection and equipment safety in tray environments.
- Conductor Size: Choose 4 AWG for mid-range power needs and 4/0 AWG for higher amperage requirements. Heavier conductors handle more current but require larger terminations and pathways.
- Length Considerations: Shorter runs reduce voltage drop and ease installation. Longer runs reduce splice points but demand careful routing and pull planning.
- Conductor Strand: The strand count (e.g., 7/.0772 or 19/.1055) affects flexibility and strength. Higher strand counts offer easier pulling but may be bulkier to terminate.
- Installation Environment: Ensure the tray cable rating aligns with indoor use, UV exposure, or chemical resistance as needed by the facility.
FAQ
- What is THHN-PVC tray cable used for? It is designed for electrical distribution in trays, offering insulation and protective jacket for indoor installations in commercial or industrial settings.
- Why choose a grounded cable? Grounded cables provide a dedicated grounding path that improves safety in fault conditions and protects equipment.
- How do I determine the right conductor size? Consider the load, distance, voltage, and allowable voltage drop to select an appropriate AWG size.
- Can I mix different lengths in a single project? Yes, but plan for splices and maintain continuous grounding continuity where required.
- What installation precautions are essential? Use proper pulling techniques, correct bend radii, and compatible terminations to avoid insulation damage.
- Are these suitable for outdoor use? The listed products are intended for tray installations typically indoors; check product specifications for outdoor suitability if applicable.
