I don't know Keith... Normally, once whatever initiated the arc is vaporized, the arc goes away at 240 V. Not always, though. Even if the arc is sustained, the heat energy is normally not as high as for a 480 V fault. But you are in a class by yourself.

They keys are:"gap", availability of the conductor(electrode) maintaining that "gap" and the source. If the gap widens fast (conductors melting fast), then the arc dies out quickly.
The truth is, I never had a chance to observe it 'cuz I closed my eyes when I had my bad day once!
