We are on a project and the electrical contractor was pulling in a 480v 3 phase 400A 520' long parallel 350 MCM pull into the building. During the pull at about the 250' mark, one of the conductors slid off the pully and sliced the insulation to the copper. The electrical contractor attempted to repair the damaged insulation on the conductor with a combination of heat shrink and liquid electrical tape and not tell anyone. Once we were made aware we told them they had to replace the conductor. Other than best practices where can I find in the code book that this is not acceptable?
