01Identify Type TC-ER Cable Before Requesting an Offer
Type TC-ER is multi-conductor copper tray cable used for power and control circuits. The cable described here carries a 600 V rating and uses THHN/THWN-2 or XLPE conductors under a PVC jacket. UL 1277 covers tray cable, and NEC Article 336 addresses its installation and use.
A typical jacket marking reads “TYPE TC-ER 3/C 12 AWG CU THHN/THWN-2 600V W/G.” TYPE TC-ER identifies the cable type and exposed-run designation; 3/C identifies three circuit conductors; 12 AWG gives their size; CU means copper; THHN/THWN-2 identifies the conductor insulation designation; and W/G indicates a grounding conductor.
The ER marking permits exposed-run applications under applicable NEC conditions, not unrestricted installation anywhere. Have a licensed electrician or engineer determine suitability for a particular installation. For a buying review, photograph the complete marking and reel tag. Our reel tag and jacket print guide explains which identification details to capture.
02Sizes, Conductor Counts and Put-Ups We Buy
We review TC-ER cable in these conductor sizes: 18 AWG, 16 AWG, 14 AWG, 12 AWG, 10 AWG, 8 AWG, 6 AWG, 4 AWG, 2 AWG, 1/0 AWG, 2/0 AWG, 4/0 AWG, 250 kcmil, 350 kcmil and 500 kcmil. Include the size exactly as printed rather than estimating it from the cable’s outside diameter.
Conductor count matters alongside gauge. Report the complete count shown on the jacket or tag, and note whether the cable includes a grounding conductor. Do not assume every reel has the same construction because the outer jackets look alike.
We buy full reels, partial reels, cut lengths, coils and boxed surplus when the material is reusable. Identify each separate length and distinguish measured footage from estimates. For mixed inventory, group matching cable by size and construction. Our wire reel selling page covers reel-based surplus; loose cable also deserves review when its identification and condition are clear.
03Why Sell Tray Cable as Reusable Surplus?
Reusable tray cable is usually worth more than its scrap, or melt, value because its value includes a finished cable construction, not just copper content. Clear identification, useful continuous lengths and sound packaging help establish whether the cable can remain usable material. An incomplete reel can still deserve review.
Our offer considers the copper market, cable type and current demand, conductor size, footage, reel or packaging condition, manufacturer and date code. Total quantity and pickup logistics also affect the assessment. A heavy reel alone does not establish its reusable value, and weight does not tell us the available continuous length.
Short pieces, burned cable, cut-up material and heavily damaged cable may be better suited to scrap. We focus on reusable material and will tell you what appears reusable rather than treating every load as resale inventory. Keep intact lengths separate from damaged offcuts so the review reflects each group’s actual condition.
04Check Ends, Jackets and Reels Before Sending Photos
Start with the cable ends and work outward to the reel or packaging. Sealed ends help show how the material was stored, but they do not prove the cable is undamaged. Photograph open ends honestly, especially if there is visible moisture, contamination or conductor damage.
Use this checklist when preparing your inventory:
- Show whether ends are sealed, capped or open.
- Photograph jacket cuts, crushing, abrasion or heat damage.
- Show reel flanges, the barrel and any broken packaging.
- Capture the manufacturer, date code and complete cable marking.
- State the available footage or weight and how it was determined.
Keep damaged portions visible rather than hiding them under wraps. If a reel has been partly used, tell us whether the remaining cable is one continuous length or several separate pieces. The date code is one pricing factor, not a substitute for reviewing storage history and physical condition. We verify the material on site before payment under the written offer.
05Houston Plants and Contractors With Surplus TC-ER
Power and control tray cable is common in Houston plants, and surplus often remains after expansions and turnarounds. Contractors may have unused project reels or cut lengths, while plant maintenance teams may hold material that no longer matches an active job. Storeroom inventory can also include partial reels with readable tags and useful remaining footage.
We review material from refineries and petrochemical plants, industrial plants and MRO storerooms, and other Greater Houston sellers. Keep project leftovers grouped by cable type so TC-ER does not get mixed with superficially similar control or specialty cable.
Our service area is Greater Houston only: Harris, Fort Bend, Montgomery, Brazoria, Galveston, Chambers and Waller counties. Houston Wire Buyers is at 6402 McGrew St, Houston, TX 77087, in southeast Houston’s Mayfair area near I-45 and I-610. Include the actual material location when requesting an offer, because pickup logistics are part of the review.
06Get a Written Offer for Your TC-ER Cable
For sellers comparing TC-ER cable buyers, a useful offer starts with identifiable inventory. Text 951-403-5738 or email industrial832@gmail.com with clear photos of reel tags and jacket print, footage or weight, and the material’s location. Include overall reel photos and close-ups of any damage so we can review condition alongside the specifications.
We review your information and provide a written offer. After that, we schedule pickup at your site or arrange an appointment for drop-off. We verify the material on site, and payment follows the written offer. Do not assume a photo review replaces the physical verification.
You can also request an offer when you have your inventory details ready. Drop-off at McGrew St is by appointment only; call first before transporting cable. If footage, condition or inventory changes after your submission, let us know before scheduling so the offer can reflect the material actually available.
07Tray Cable Compared With Related Cable Types
Cable appearance is not enough to establish its type. A PVC-jacketed multi-conductor cable may resemble TC-ER without carrying that designation. Read the complete jacket print and use the reel tag to confirm construction; do not label mixed surplus as tray cable solely because it came from a tray installation.
THHN/THWN-2 building wire can be used as the insulated conductors inside the tray cable described here, but individual building wires are not the same finished product as a jacketed multi-conductor TC-ER cable. Control cable describes a functional category that can overlap with tray cable when the cable carries the appropriate type marking.
VFD cable may have construction features selected for drive applications; a TC-ER marking alone does not establish suitability for that duty. Keep each marked type separate for review. For installation, substitution or circuit design, ask a licensed electrician or engineer rather than relying on a surplus buying description.
FAQQuestions sellers ask
Can I submit TC-ER cable if the reel tag is missing?
Yes. Send readable jacket-print photos, overall cable photos and your available footage or weight information. Tell us the reel tag is missing rather than recreating its specifications from memory. We can review what is documented, but missing identification may limit our ability to evaluate the cable as reusable surplus.
Should I strip the PVC jacket before requesting an offer?
No—leave potentially reusable cable intact for review. Removing the jacket changes the finished product and can eliminate its reusable cable value. Photograph its markings and condition first. If the material is already stripped or severely damaged, explain that clearly so we do not assess it as intact TC-ER.
Can I offer several different TC-ER sizes together?
Yes. Submit the inventory together, but list each size, conductor count and separate length individually. Label photos so we can match them to the correct reel or coil. A combined weight without those details makes it harder to distinguish reusable cable from mixed or unidentified material.
Does a 600 V marking mean this cable is medium-voltage cable?
No. The tray cable covered on this page is rated 600 V; it should not be described as medium-voltage cable. Copy the actual voltage and type markings into your inventory submission. If the printing differs from this page’s example, send a photo rather than assuming the cable has the same rating.
Is Houston Wire Buyers affiliated with the cable manufacturer?
No. Houston Wire Buyers is not affiliated with Houston Wire & Cable Company or any manufacturer. We buy surplus material based on its documented specifications, condition and market factors. Keep manufacturer information visible because it helps identify the cable, not because we represent that manufacturer or provide installation approval.
