Know the weight
To easily determine how much wire is left on a partial spool, buy a small luggage scale. Weighing a full spool so you can calculate the weight per foot for each wire gauge. We keep one on each truck. The cost savings from being able to efficiently use partial spools will pay for the scales quickly. Even more significant is eliminating the time and frustration that results from having a conductor that is a bit too short.
A few years ago, we needed to cut about 2,000 boxes in ¼-in. steel wall at a prison. The requirement was to install a splice box over each hole on the back side in the secure chase, then drill and tap the grind smooth on the prisoner side. This would take an extensive amount of time. Instead, we purchased a stud welder to weld studs on the secure side, using a jig for location. We attached a washer and nut very quickly, which saved about 1,000 man-hours.
