"A high-performance cable engineered for industrial automation panels, signal monitoring loops, and commercial communication infrastructure. Housing three precision-insulated 18 AWG conductors in a compact, round configuration under a heavy-duty PVC outer jacket, this 600V Type TC-ER cable easily routes through crowded containment trays, factory raceways, and structural conduit pathways where space is at a premium."
When wiring intricate enclosures, machine stations, or packed trays, physical reliability equals efficiency. The 18/3 VNTC balances a compact physical footprint with industrial-grade durability. Featuring stranded copper TFFN conductors encased in a flame-retardant, UV-resistant PVC jacket, its compact round core design maximizes containment space, handles tight corners effortlessly, and slashes installation time.
Exposed Run (TC-ER) Certified: Fully code-listed to transit safely outside of protective cable trays or conduits in unprotected open-air spans directly to mechanical enclosures when properly supported.
Versatile Routing Approvals: Fully code-compliant for deployment in open-air trays, supported by messenger wire, pulled through structural conduits, or laid in deep under-floor ducts.
Direct Burial & Outdoor Rated: Built with a sunlight-resistant, moisture-proof outer shield that permits direct underground trenching and exposed outdoor installation.
Compact Round Core Assembly: Features conductors cabled tightly together with or without fillers and finished with a protective binder tape to form a perfectly round profile for smooth pulls.
TFFN Conductors: Individual conductors feature fine copper stranding to deliver superior bend radii and defend control circuits against physical fatigue from machinery vibration.

An 18/3 Tray Cable is engineered to transmit low-amperage command signals, sensor data, and communication relays rather than supply raw machinery power. It is heavily utilized to link industrial control buttons, emergency shutoffs, automated valves, and facility thermostats back to central processing panels and PLC boxes.
Following the standard industrial triad layout (ICEA Method 1, Table E-2), this 3-conductor cable contains one Black, one Red, and one Blue conductor, with each wire numbered for fast field matching. Please note that this specific tray cable configuration contains no white neutral wires, green grounding wires, or colored stripes.
Yes, absolutely. The dual-layer protection of the tough PVC/Nylon wire coatings combined with the specialized outer Polyvinyl Chloride (PVC) jacket makes this cable fully certified for direct burial in underground trenches, wet settings, or concrete encasements. It features a robust sunlight-resistant rating, meaning the jacket will not degrade, crack, or bake when exposed to harsh outdoor UV rays.
This 18 AWG copper conductor carries an absolute maximum allowable ampacity of 6 Amps at a continuous 90°C thermal threshold. Because control lines are engineered strictly for low-load data pulses and system triggers, continuous operational equipment draw should always be capped safely below this 6-Amp ceiling.
Wire America supplies an extensive inventory of tray cable cut by the foot or on master reels. We ship directly from our regional hubs located across the United States, delivering most orders right to your shop or job site within 2 to 4 business days. We prioritize shipping tray cable from the warehouse nearest to your job site to keep transit times minimal. Expedited shipping options are available at checkout for time-sensitive contractor deadlines.
