How much electricity can a 10 gauge wire carry?

Example relating to RVs: A 10 gauge wire can carry 30 amps of electricity at any voltage. Therefore, a 10 gauge wire can carry 360 watts (10 amps X 12 volts ) of 12 volt automotive power or 3,600 watts (10 amps X 120 volts) of 120 volt household electricity. The latter is ten times more energy through the same size wire!
