I wanted to run power to my barn which is 500 ft away from the main panel. I'm on a tight budget and wanted to still be able to do it correctly without causing fires or too much drop in voltage. I was considering using either 500 ft of uf-b 8/3 or two separate lines of uf-b 12/3. In the barn I'll have my office upstairs that will have a 13.5 amp portable heater running along with a few lights about 5 amps. Down below about 5 amps of lights for the animals and a small heater also pushing 13.5 amps. If I use the uf-b 12/3 will there be any issues? thanks.
