Wire sizes get larger as the gauge number gets lower, from 40-gauge all the way down to 0-gauge or 0.325 inches. Sizes larger than 0-gauge are listed as 00, 000 and so on. Wire with a low gauge will be harder to work with, and larger wire cutters may be necessary. AWG is measured differently for solid wire than it is stranded wire.

The answer to your question is per the NEC Table 315 (B) (6), which states that for a service of 400A, 400 kcmil conductors are needed for the phases and the neutral for copper wire and 600 for aluminum. For the grounding conductor, the size would be taken from table 250-66 of the NEC, and would be 1/0 for 350-600 kcmil if copper and 3/0 if ...

You are correct that 600kcmil is the right size for using a single wire per leg for the service entrance, though -- this gives you 340A at 75°C, just enough to meet our 332A requirement. Furthermore, it is about $0.50/ft cheaper at the time of this writing than the parallel conductors, and also takes up slightly less conduit area, albeit not ...And what size wire do you need according to 310.15(B)(7) Remember you are sizing your full 195 amp load of this chart, using 2/0 hots.
