At what sizes do power cables typically use solid conductors?

Power cables typically utilize solid conductors for smaller sizes, particularly those smaller than 2 AWG, due to several important factors. Solid conductors are advantageous in these smaller sizes because they are more flexible and provide greater ease of handling during installation. Additionally, solid conductors exhibit lower resistive losses in the smaller gauge sizes, making them more efficient for applications that do not require the greater flexibility afforded by stranded conductors.

In contrast, as the sizes of conductors increase, particularly at or above 2 AWG, the demand for flexibility and ease of installation in certain applications often makes stranded conductors more desirable. Stranded conductors, made up of multiple smaller wires, can bend and twist more easily, accommodating complex installations while still delivering the necessary electrical performance.

Thus, when looking at the size of power cables where solid conductors are most commonly used, those smaller than 2 AWG are indeed the standard choice due to these specific benefits.
