There was someone working on a building about 150' away from the main building. The crew must have had some extension cords. The cords they had didn't quite reach to the job site. So, they just went and added 2 pieces of 10 AWG THHN. They wrapped the wire around the plug so that the cord was now able to reach their job site.
In the main building the wires were attached to a circuit breaker, not even GFCI protected even though they were working outside.
