If I run 100' of underground wire, which size would I need to operate radio, two lights, bugzapper, and a electrical cooler. 12-2 UF-B W/Ground 600 volts 20 amps, or could I use 14-2 UF-B W/Ground 600 Volts 15 amps, or do I need something larger. Dont want to run the wrong size and drop to many volt getting there.
