It's all about the resistance of the wire. More resistance = more power loss.



But, if you only have small gauge wire, using higher voltage allows it to
conduct more power.

My Coax has performed pretty well at 100V at 8A..
The heat dissipation is minimal. But if I were using really small wire,
with a lot of resistance, it could get hot and even melt in half.
