Which is larger? #1 copper or #2 aluminum

When comparing wire sizes, it is essential to understand the American Wire Gauge (AWG) standards and the characteristics of different materials. In this case, #1 copper wire is larger than #2 aluminum wire when comparing the same gauge size.

Copper has a higher conductivity than aluminum, which allows for smaller sizes of copper wire to carry the same amount of current as a larger size of aluminum wire. The physical size of conductors is also an important consideration; #1 copper wire has a larger cross-sectional area than #2 aluminum wire, meaning it can handle more current with less resistance.

Therefore, #1 copper is larger and more efficient for electrical applications compared to #2 aluminum. This makes it the better choice for many wiring applications due to its superior electrical properties and lower resistive losses.
