Which statement regarding the fault current of an arcing short-circuit condition is accurate?

The statement regarding the fault current of an arcing short-circuit condition being more due to additional resistance of the arc is accurate. When a short circuit occurs, the circuit is shorted directly by conductors, leading to a situation known as a bolted short-circuit. In this case, the fault current is at its maximum because there is minimal resistance in the path of the current flow.

In contrast, during an arcing short-circuit, the arcing creates a significant resistance due to the ionized air or gas between the conductors. This resistance reduces the overall fault current compared to a bolted short-circuit condition. However, the presence of the arc and the manner in which it conducts current can result in varying levels of fault currents that are typically higher than non-arcing conditions, but still less than bolted shorts. This distinction is crucial for understanding how arcing impacts fault current levels and the resulting effects on electrical systems.

Choosing this option reflects an understanding of the differences in fault current dynamics between arcing and bolted short-circuit scenarios, particularly regarding resistance and its effect on current flow.
