What can the temperature of arc terminals reach during an arcing-fault event?

During an arcing fault event, the temperature of arc terminals can reach extremely high levels due to the significant energy released in the form of heat. The correct answer indicates that these temperatures can peak at around 35,000°F. This is particularly alarming as such high temperatures can cause extensive damage to electrical components and related infrastructure.

Arcing faults occur when there is an unintended electrical discharge between conductors or between a conductor and the ground. The heat generated from this discharge is sufficient to vaporize metals and can lead to fires, equipment failure, and safety hazards. Understanding this temperature range is crucial for professionals in the field, as it emphasizes the importance of implementing adequate safety measures and protective devices to prevent arcing events and enhance overall electrical safety.
