At what voltage are hot line tools factory tested per foot?

Hot line tools are essential for ensuring the safety of workers who operate on or near energized electrical lines. The factory testing of these tools is conducted to guarantee that they will perform effectively and safely under high voltage conditions.

The industry standard for testing hot line tools is to ensure they can withstand significant electrical stress. A testing voltage of 100,000 volts per foot reflects the rigorous safety and durability requirements set for tools used by professionals in the field. This high level of testing ensures that the tools can effectively prevent electrical shock hazards during operations.

The other voltage options do not meet the required standards for hot line tool testing, as 100,000 volts per foot is established as a benchmark to provide sufficient insulation and protection for users working with live electrical systems. Therefore, the correct answer signifies the requisite level of safety and reliability for these vital tools.
