Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:

These specifications cover the equipment making up the temporary grounding system used on de-energized electric power lines, electric supply stations, and equipment. These specifications for a system of protective grounding utilizing copper cables are covered in four parts, as follows: clamps, ferrules, cables, and temporary protective grounds. Each of the four parts is an entity of itself, but is listed as a part of the system for completeness and clarification. The clamps shall be subject to design tests for determining mechanical torque strength and electrical short circuit capacity. The ferrules shall be tested for electrical short-circuit capacity and continuous current rating. The elastomer or thermoplastic making up the jacket of the flexible cable shall be tested according to the specified methods.
