Which statement about arcing faults is correct?

The statement indicating that shorter duration arcing faults release less energy is correct because the energy released during an arcing fault is directly related to the duration of the fault. When an arcing fault occurs, the energy is dissipated in the form of heat and light, with the amount of energy being contingent on how long the fault persists.

With shorter-duration faults, there is less time for energy to build up, resulting in a lower total energy release. Conversely, if an arcing fault lasts longer, it has more time to generate heat and sustain an arc, leading to a higher energy release, which is critical in understanding the risks associated with electrical faults.

Understanding the relationship between fault duration and energy release is essential for implementing appropriate safety measures and determining the severity of potential hazards associated with electrical systems.
