Automotive supplier plants
Supplier plants run welding cells, press lines, conveyors and paint support equipment, and each of those has its own electrical signature. Welding cable carries the heavy current at the guns, tray cable runs power and signal between cells, and control cable interlocks the line so one fault stops everything downstream. A supplier plant also keeps spare drive cable, since a shielded run cannot be replaced with ordinary tray in a hurry.
Tooling changes are the main source of surplus. When a cell is rebuilt for a new model, the cable that fed the old layout is pulled out, and a good deal of it is still serviceable. We buy those lots by the pallet and price them on construction, since a tray cable with a shield is worth more than one without.

Machine shops and tool rooms
The shops that support the assembly plants run lathes, mills, robots and test stands on modest power. Their stores hold part reels of THHN and XHHW, armored MC for exposed drops, and cord for portable equipment. Most of it is bought in small quantities and used slowly, which is how part reels come to exist.
Shop surplus is small and spread out, and we treat it that way. A single visit can cover a tool room and a maintenance crib if they are on the same site, and pricing the whole lot together usually beats pricing each shelf separately for both sides.

Commercial work at the park gateway
US-129 carries visitors toward the Smokies, and the businesses that serve them renovate on a tourist calendar rather than an industrial one. Lodging, restaurants and retail fit-outs consume building wire, MC and service-entrance cable, and each renovation leaves a remainder in a contractor's shop or a maintenance closet. Lodging work in particular repeats the same layout many times over, which multiplies the leftovers.
That material is usually conventional and lightly used, which makes it easy to price. What it lacks is documentation, since a small commercial job rarely keeps a cable log. We identify by jacket print and by conductor count, and we quote on the assumption that the material is standard until proven otherwise.
