350 kcmil Copper Wire. 500 kcmil Aluminum Wire. 400 Amps. 400 kcmil Copper Wire. 600 kcmil Aluminum Wire. This table is quite easy to use. For example, let’s say you are trying to figure out the feeder wire size for 300 amp service. By checking this table, you can see you will need either 4/0 AWG copper wire or 300 kcmil aluminum wire to ...AWG Formulas. According to the American Wire Gauge (AWG) method, the highest Gauge of a wire is Nr. 36 AWG, and the smallest Gauge is Nr. 0000. The diameters of these two are 0.005 inches and 0.46 inches, respectively. There are 40 gauges between these largest and smallest sizes, or you can say 39 steps.The usual recommendation is 2 AWG Aluminum, which will handle up to 90A. Based on "6 space panel" and no mention of on-demand electric water heating (don't, just don't) or of EV charging, I can't imagine you really expect to use anything close to 100A peak/80A continuous. If you do, then jump up to 1 AWG Aluminum.
