4/0 al @ 75 deg is good up to 180 amps [see nec table 310.15(b)(16)]. Best outcome is you use a cable thicker than you need and waste money, worst case your cable is too thin and you start a. The neutral wire is often one or two sizes smaller than the two hots.

Going back to the example i share above, if we simply bump the load to 125a, you’ll already need a 2/0 aluminum wire instead, which is obviously entirely different from the 125 amp wire size copper i mentioned. I think what they're trying to say is your wires can have a temperature rating of 60c or 90c your wire can have a temperature rating of 60c if your control panel is 100a or less (yours is 100a) your wire should have a rating of 75c or 90c if your panel is 125a or higher (this is not your case) the voltage drop for the wire bringing power to your control panel is figured by the run length. Distance is 160 foot from meter to breaker panel.

Table 310.15(B)(16) Says That 1 Awg Copper Is Good For 130 Amperes At 75C.
