Record the circuit
Which feeder, which voltage, which service. That single line tells a buyer what duty the cable saw and whether the insulation was stressed by load or environment.
Record the removal
Date, who removed it, and how. Cable pulled with a tugger and cable cut out in sections are different propositions, and the difference shows at the ends.
Record the condition at removal
Sealed ends, jacket damage, moisture exposure, kinks from coiling. Notes taken at removal are credible; notes written a year later are not.
Photograph before storage
Photographs taken at removal, with the reel tag in frame, settle most later questions and prevent a good lot being priced as unknown.
