Contractor leftover wire from Springfield job trailers

What accumulates by the end of a job

A crew does not throw away usable wire. Every electrician on a job keeps the four-foot tail from a pull, the half coil of 12 AWG left after a lighting run, the box that was opened for six devices and closed again. Multiply that by a shift, a subcontractor and a year on a plant redevelopment and the trailer is full.

The composition is predictable. THHN and THWN in small and mid gauges, mostly 12 and 10, in several colors because nobody buys only black. MC cable in short lengths with the armour already cut. Fixture wire, control cable offcuts from a panel change, cord and cap assemblies, and a length of bare copper that was a grounding electrode conductor until it was cut too short.

Sorting is most of the work

A mixed pile of cut-offs is reviewed at the value of its worst component, because that is the only honest way to describe it. Sort it first and the same material becomes several lots with different characters: solid copper THHN by gauge, stranded control and machine tool wire, aluminum if any, bare copper, and a residual pile of cord, tape and scrap ends.

The sort does not need to be perfect. It needs to separate by conductor metal, by insulation type and by whether the length is usable. Three gaylords of sorted material can be described in a paragraph. One gaylord of everything cannot be described at all, and the seller ends up accepting a number based on the worst thing in it.

• Solid THHN / THWN, 12 and 10 AWG, sorted by color
• Stranded control and machine tool wire
• MC cable offcuts with armour cut back
• Bare copper and grounding tails
• Cord, cap assemblies and taped ends

Who owns the leftovers

On a redevelopment job the answer is less obvious than it sounds. Material bought on the contract belongs to the owner once installed and to the contractor while it sits in the trailer, and the two do not always agree about the coil that was never opened. Subcontractors leave material behind when they demobilize, and it becomes the general contractor's problem.

The practical rule is to settle ownership before the trailer is emptied, not after. A written note from whoever is running the job, naming the material and confirming it can leave, prevents the awkward call that arrives when a project manager returns from a site visit and finds the yard cleared.

Review and pickup at demobilization

The best time to review is the week the trailers are being pulled off site, because the material is still in the containers the crew used and the foreman is still reachable. Springfield's large former plants are spread along the I-70 corridor with CSX behind them, and a trailer or a straight truck usually fits the yard better than a full flatbed.

Review is by count and sample: how many coils, what gauge, is the print legible, is there aluminum in the pile. Weight is taken at a certified scale before the vehicle leaves. Terms are written against the sorted containers, so a pickup can proceed one gaylord at a time if the site needs the space back before the job is formally closed.
