An electrical arc can reach temperatures as high as what?

An electrical arc can indeed reach temperatures as high as 35,000 degrees Fahrenheit. This temperature is significant because it showcases the immense heat generated during an electrical fault or arc flash event. Such high temperatures can lead to severe burns, ignite flammable materials, and cause extensive property damage. Understanding the potential for these extreme temperatures is crucial for linemen and other electrical workers to implement proper safety measures, use appropriate personal protective equipment (PPE), and follow industry standards designed to protect against arc flash hazards.

The other options suggest even higher temperatures, which exceed documented values for typical electrical arcs. While some phenomena may generate extremely high temperatures, in the context of electrical arcs encountered in utility work and training, the maximum commonly recognized is around 35,000 degrees Fahrenheit. Therefore, knowing this helps reinforce the safety protocols needed when working near electrical equipment.
