Control cable: 600 V multiconductor, numbered and shielded
Control cable is the smallest cable in the plant and the one that stops the plant. A 14 AWG multiconductor with numbered conductors and a foil shield is worth more as a reel than as copper, and that is the whole argument.
- 600 V multiconductor
- 14, 12 and 10 AWG
- Numbered and shielded
The standard product is a 600 V multiconductor with 14, 12 or 10 AWG conductors, laid up or twisted in pairs, numbered or colour-coded, jacketed in PVC or a low-temperature compound, and often shielded with an overall foil and a drain wire. Conductor counts from two to thirty or more are ordinary. A Type TC rating to UL 1277 puts it in tray, and TC-ER puts it in exposed runs.
Control cable carries the signals that make a motor starter pull in, a valve stroke or a permissive pass. It is not sized for ampacity the way power cable is; it is sized for mechanical robustness and for voltage drop over a long run. That is why 14 AWG dominates, and why one plant can hold thousands of feet of it in twenty conductor counts that no other kind of building would stock.
We buy partial reels from plant change-outs, full reels from cancelled projects, and the mixed pallets that come out of an MCC room when a line is rebuilt. Numbered conductors with legible print are the easiest to place. Twenty short cut-offs with the numbers worn off are not, and we say which is which before terms are set. A reel with a tag and a legible print is stock; a coil of loose ends is recovery.
What we buy in this family
Condition and documentation decide the basis, not the family alone. These are the forms this material usually arrives in.
- 600 V multiconductor control cable
- Numbered and colour-coded constructions
- Shielded control cable with drain wire
- Type TC and TC-ER tray rated
- 14, 12 and 10 AWG conductor counts
- Partial reels from MCC change-outs
- Armoured and interlocked variants
What a control cable lot is actually made of
A pallet from an MCC room is a history of the plant. There will be a part reel of 19 conductor cable from the last line addition, four coils of 7 conductor in two sizes, a reel of shielded 12 AWG for a drive permissive, and a box of ends too short for anyone to label. Nobody sorted it when it went on the shelf.
That mixture is normal and it is not a problem, provided the seller describes it as a mixture. We review each grouping on conductor count, size, shielding and remaining length, then write one set of terms naming what is included and what is treated as recovery.
Shielding, numbering and the details that place a reel
An overall foil shield with a drain wire is the most common shielded construction, and the drain is what fails first in storage, because it is a single small conductor that kinks when a reel is handled carelessly. Braid shields cost more and tolerate more abuse. Either way, a broken drain is a repair decision.
Numbering is what turns a reel into stock. Print that reads 1 through 19 in a legible sequence can be trusted on a job. Print that has gone pale must be rung out and re-identified before an electrician will use it, and that labour is what a buyer is trying to avoid.
Storage, jacket damage and the cost of a missing tag
PVC jackets harden with age and heat, and a reel that spent a decade in an unventilated mezzanine will crack when it is bent rather than flex. That is not visible in a photograph of the flange, which is why we ask for a picture of the exposed end as well as the tag. Where the tag is gone, the print carries the same information at a cost to the seller.
Where this cable turns up in the two states
Textile plants left the Carolinas with more control cable in their walls than any modern building holds. Relay logic, pushbutton stations and motor control centres were wired in multiconductor cable, and a change-out in a former mill building still turns up reels and cut lengths of it. Upstate automotive plants generate the same family in newer constructions at far higher conductor counts.
Charleston’s chemical plants and the paper and manufacturing sites across the Piedmont run control and instrument cable on tray for the length of a process unit, and a turnaround produces partial reels with the tags still on them. Columbia’s manufacturing base does the same at a smaller scale, usually in 14 and 16 AWG counts and usually without anyone recording what is left.

Control cable questions
What is the difference between control cable and tray cable?
Tray cable is a rating, not a construction. A multiconductor control cable built to Type TC is tray cable as well, and both descriptions can be true of the same reel. At review what matters is whether the print shows a tray rating, what the conductor count and size are, and whether a shield is present, not which of the two names the seller uses.
Do numbered conductors add value?
They add usability. A reel of 19 conductor cable with clear numbers can go straight onto a job, while the same reel with the numbers worn off must be rung out and re-identified before anyone trusts it. That is a labour question rather than a copper question, and it decides how quickly a reel can be placed.
Can you take control cable with a damaged jacket?
Yes, and we will tell you what it does to the basis. A nick that exposes the shield braid is a repair or a cut-back. A jacket abraded along a whole length by dragging is a length question. Water that travelled under a damaged jacket is worse than the damage itself, particularly in a foil-shielded construction.
Is 16 AWG control cable common in the Carolinas?
It is common in older plants and in machine tool work, and less common in new construction, where 14 AWG is the default for control circuits. A reel of 16 AWG is perfectly usable, but the market for it is smaller, and a lot made up mostly of 16 AWG counts and odd conductor numbers takes longer to place than a clean 14 AWG lot.
