Type TC-ER Cable 4 Core 10AWG UL1277

A single cable failure in an automated production line isn’t just a repair ticket. It’s unbudgeted downtime, cascading sensor faults, and a scramble to re-pull cable through packed trays. Most of these events trace back to one decision: using tray cable that isn’t truly built for exposed runs, constant flexing, or oil-saturated industrial air. The 4-core 10AWG TC-ER cable we ship directly from our factory closes that gap. It combines a UL1277-listed construction with an oil- and sunlight-resistant jacket, so you get one cable type for tray, conduit, and outdoor aerial use — fewer part numbers, simpler inventory, and significantly lower installed cost per foot.

Conductor sizing that matches the load, not the guesswork

Solid or stranded tinned copper, 10 AWG precisely drawn and bunch-stranded to UL 1581.
Stranding keeps the cable flexible enough for tight control panel bends, yet the cross‑sectional area holds a steady ampacity under continuous industrial loads.
What it means on your floor: you can standardize on 10 AWG for 30‑40 A motor branch circuits without worrying about thermal derating surprises during summer shifts.

Exposed-run approval (ER) without the “cheap jacket” compromise

TC-ER rating per UL 1277 means this cable is approved for use in cable trays and exposed runs — no conduit required where the NEC permits.
The jacket is a flame-retardant, sunlight-resistant PVC compound. It passes UL 1581 sunlight resistance and oil resistance testing.
For your project schedule: the same reel you use inside a tray at the machine level can route directly to a rooftop ventilator without a transition box or separate UV-rated conduit. Less labor, fewer joints.

Four cores, one clean bill of materials

4‑core configuration gives you three phases plus a ground, or two power conductors and two signal interconnects in a single jacket.
Concentric geometry keeps the outer diameter compact — easier pulls through ladder rack and tight conduit fills.
Procurement impact: you reduce the number of cable SKUs on a typical motor-control installation. One cable design covers VFD motor leads, disconnect loops, and bypass circuits.

Factory-direct lot traceability, not repackaged mystery reels

We manufacture under ISO 9001‑certified procedures. Every master reel carries a heat‑code traceable to the copper source batch and extrusion date.
This gives you full documentation when your end customer (or an underwriter) asks for the paper trail on a 9,200‑foot order.
Supply chain effect: you’re buying from the extruder, not a consolidator. Shorter chain means you’re insulated from the “substitute a similar cable” practice that inflates field acceptance delays.

Industry Applications & Scenario Validation

• Automated production line power distribution
  Handles continuous minor flexing and oil splatter near CNC machines and robotic cells without the jacket hardening that triggers early replacement.

• HVAC equipment and rooftop unit wiring
  TC-ER rated for exposed outdoor runs eliminates a weatherproof conduit transition at the roof penetration — one less sleeve to leak.

• Material handling and conveyor systems
  4‑core 10AWG feeds multiple motors along a single tray route; the compact diameter keeps fill rates legal inside long, crowded tray runs.

• Water and wastewater treatment facilities
  Withstands the daily thermal cycle and chemical‑laden humidity in aerator galleries and pump houses without jacket deformation.

• Portable power distribution and temporary site power
  A rugged jacket and stranded copper allow re‑deployment across job sites without the conductor fatigue that solid-core building wire would suffer.

FAQ

Does TC-ER cable need conduit when run exposed above a drop ceiling?
In most U.S. jurisdictions under the NEC, TC-ER cable is permitted in exposed runs where not subject to physical damage. If your installation is in a dropped ceiling used for air handling, check local amendments — we can provide a white‑print letter from our UL file to support your submittal package.

Can the jacket be printed with our project label and sequential foot markers?
Yes. Surface ink‑jet printing is done in‑line during extrusion. You can have your company name, reel number, footage markers, and a simple wire color table. There’s no extra charge for standard black‑on‑black or white‑on‑black printing on orders over 5,000 feet.

What is the factory’s lead time for 10 AWG 4‑core TC‑ER, and do you hold buffer stock?
We keep 10 AWG 4‑core in rotation for spot‑buy requirements. Typical shipment for stocked items is 5 to 7 business days after order confirmation. Made‑to‑length orders with custom printing usually ship within 14 business days. We ship on export‑grade wood reels with sealed polythene wrapping.
