If you compare two conductors, 4 AWG and 6 AWG, which is larger in diameter?

Explanation:
In the AWG system, smaller gauge numbers mean thicker conductors. So a 4 AWG wire has a larger diameter than a 6 AWG wire. This reflects more metal cross-section, which also means lower resistance per length and higher current-carrying capacity. Since you’re asked which is larger in diameter, the thicker, lower-numbered wire is the correct choice.
