What voltage is considered "high voltage"?

The understanding of what constitutes "high voltage" is critical in the electrical field, particularly for outside linemen. According to industry standards, "high voltage" typically refers to any voltage level above 1000 volts for alternating current (AC) systems. This classification is set by organizations such as the National Electrical Safety Code (NESC) and the International Electrotechnical Commission (IEC).

Thus, the provided answer stating 600 volts as high voltage is misleading because it falls below the threshold that is generally recognized in most electrical safety standards. High voltage systems present unique hazards and require specialized training, tools, and safety measures. Recognizing the correct threshold ensures that linemen approach their work with the appropriate precautions and awareness of the risks involved.

Only alternatives that are 1000 volts or higher are accurately classified as high voltage, making it crucial for professionals in the field to have a clear understanding of these classifications to maintain safety and compliance.
