#4-3C Tray Cable With Ground — 100ft
Size: 4 AWG, Conductor Count: 3, Conductor Strand: 7/.0772. Best for short feeder runs in controlled environments where a compact length is needed. This product is well suited for panel wiring and clean installations in equipment rooms. Choose this if you need precise, shorter runs with a ground conductor for safety. Limitation: shorter length may require more splices for longer installations.
#4-3C Tray Cable With Ground — 300ft
Size: 4 AWG, Conductor Count: 3, Conductor Strand: 7/.0772. Better for medium-length runs in industrial settings or data centers where a stable ground is essential. This length balances ease of handling with installation efficiency. Avoid this if space constraints require very short segments or if additional splices are not desired.
#4-3C Tray Cable With Ground — 450ft
Size: 4 AWG, Conductor Count: 3, Conductor Strand: 7/.0772. Suitable for longer feeder routes or equipment rooms with fewer intermediate connections. Best for projects prioritizing fewer terminations and more continuous grounding. Limitation: longer runs may require careful routing to prevent physical damage.
#4/0-3C Tray Cable With Ground — 350ft
Size: 4/0 AWG, Conductor Count: 3, Conductor Strand: 19/.1055. Best for higher-current feeder applications where space permits larger conductors. Choose this if your system requires heavier conductors and a robust ground. Caution: significantly larger diameter may impact tray clearance and bend radii.
#8-3C Tray Cable With Ground — 450ft
Size: 8 AWG, Conductor Count: 3, Conductor Strand: 7/.0486. Best for lighter feeder duties in compact installations or where flexibility matters. Choose this if space is tight and you need easier routing around obstacles. Limitation: lower voltage and current capacity compared to larger gauges.
Buying Guide
Key considerations when selecting 4/3C THHN-PVC tray cable with ground:
- Conductor size and current needs: 4 AWG supports heavier loads; 8 AWG suits lighter feeders. Match to circuit requirements.
- Ground configuration: all recommended options include a ground conductor for safety and code compliance; assess grounding needs based on installation environment.
- Length and handling: choose lengths that minimize splices and maintenance while fitting tray layouts and bend radii.
- Insulation and tray compatibility: THHN-PVC insulation is common for tray systems; verify compatibility with your tray material and temperature rating.
- Environmental conditions: consider moisture exposure, chemical exposure, and ambient temperature when selecting insulation and conductor strands.
- Code compliance: ensure the chosen cable meets local electrical codes and installation standards for tray systems.
FAQ
- What does THHN-PVC Tray Cable mean?
- When should I use a ground-equipped tray cable?
- What gauge should I choose for high-current feeders?
- Can I mix lengths in a single tray system?
- Is there a difference between the 3-conductor and 4-conductor tray cables?
- Do these cables meet electrical codes?
THHN-PVC refers to conductor insulation (THHN) in a PVC jacket designed for installation in electrical trays or conduits.
Use grounded cables for safety and compliance in most feeder applications where a protective ground path is required.
For high-current feeders, 4 AWG or 4/0 AWG is typical, depending on distance, voltage, and current requirements.
Yes, but plan routes to minimize splices and maintain consistent grounding and safety margins.
These entries describe 3-conductor cables with a separate ground; 4-conductor cables are less common in this 3-conductor-with-ground format but verify exact configurations for your project.
