How does the arcing current at 208 volts compare to the arcing current at 480 volts?

Arcing current increases with voltage due to the characteristics of the electrical arc. At higher voltages, the potential difference facilitates a stronger and more sustained electrical discharge, resulting in a greater arcing current. Specifically, 480 volts represent a higher potential difference than 208 volts, which enables more current to flow through the arc when conditions permit. Therefore, while arcing current at 208 volts can still present serious hazards, it generally exhibits a lower magnitude compared to that at 480 volts. This principle is fundamental in understanding electrical safety and the risks associated with high-voltage systems, particularly in terms of protective measures and equipment ratings.
