At what temperature does an arc flash occur?

An arc flash can occur at extremely high temperatures that result from an electrical fault, where the energy released can create an intense heat and light. The correct answer indicates that arc flashes can reach temperatures between 5,000 to 35,000 degrees Fahrenheit. This range is significant because it highlights the potential for severe burns and damage to materials in proximity to the arc flash, illustrating the dangers faced by electricians and individuals working with electrical systems. Temperatures in this range can quickly ignites clothing and other flammable substances, which is why stringent safety measures and protective equipment are critical in environments where high-voltage electrical work is conducted. The other temperature ranges provided do not accurately encompass the high-energy and thermal effects associated with an arc flash phenomenon.
