6-4 Type G Portable Cord, Black, 2000V

G-GC cord is a heavy-duty, portable power cable used in industrial and mining settings, featuring a main power circuit plus extra grounding, specifically with a bright yellow "ground check" conductor (the "GC") to monitor the integrity of the safety ground, quickly de-energizing equipment if the ground path breaks to prevent electrocution. The "G" signifies grounding, and it typically contains three power conductors, two standard green grounds, and one yellow ground check conductor, making it suitable for demanding applications like mining equipment, cranes, and conveyors.
