@fcktheworld587 >someone getting close enough to cause an arc
I don't know very much about the behavior of electricity, but I would reckon that at the voltage and amperage that's running at, it won't arc (considering the metal terminals are separated by 2mm of air and there isn't any visible arcing) and getting close wouldn't be a problem - but you would clearly receive a shock if you touch it and you're an easier path for the electricity to travel.
