01
University and institutional maintenance
The University of Tennessee at Martin keeps the kind of store a campus needs: building wire for renovations, armored cable for corridor and classroom runs, and control wire for mechanical equipment. Work is planned, so material is ordered to a schedule and the remainder goes back on a shelf with its tag still attached and its length noted.
Campus surplus is usually clean and clearly marked. What it lacks is volume in any one size, since a renovation may leave forty feet of 10 AWG and nothing else. We buy those lots as a group and price the mix rather than the single reel, which is fairer to the seller than quoting each stub separately.

Weakley County processing plants
Agricultural processing in the county runs on motors, augers, conveyors and cold storage. That equipment draws THHN and XHHW for feeds, tray cable for runs between buildings, and cord for anything that has to move during a shift. Plants also keep pump cable for wells and washdown points on the site. Cold storage in particular keeps a spare reel of control cable, since a failed compressor will not wait for a purchase order.
When a line is reconfigured, the cable that served the old layout is cut away and coiled. Some of it is reusable and some is not, and the difference is usually visible at the ends: crushed armor or a stretched jacket means that run is finished. We look at the ends before we look at the footage.
03
Contractors and farm service work
Electrical contractors working out of Martin cover a wide radius of farmland and small towns. Their trucks carry part reels, and their shops carry more: service-entrance cable for barn services, pump cable for well work, and cord for equipment repairs. At the end of a season, a good deal of it is still on the shelf.
Farm leftovers are the least documented lots we see. A coil of SER pulled from a barn may carry no tag at all, only a memory of which building it came from. We identify it by conductor count, insulation and jacket marking, and we tell the seller what we found before any number is discussed.
