Here is an easy way to remember. 10 Ga wire has 1 ohm per 1000 feet. The resistance changes as power dB. going 10 more gague numbers to 20 gaue gives you 10 ohms per 1000 feet.
The usual sizeing for long distances is a 2% voltage drop maximum
Fusing current is 333 A for the 10 Ga wire with again the power dB rule.
The general short length limits are 30 A for 10 Ga and scaling by a factor of 4 for 10 Ga number differences.
Voltage and current are VERY dependent upon insulation type, not just the gauge of the wire. The insulation usually melts before the wire when put to the limits concerning current. The voltage rating is completely dependent upon insulation. I have a chart regarding this info but I can't upload info till Monday (it's at work). You can look to wire manufacturers tech info web pages for more info (check out www.belden.com ).
