Conductors larger than which gauge are typically expected to be stranded?

Conductors larger than 8 AWG are typically expected to be stranded due to a combination of flexibility and practical installation considerations. Stranded conductors are composed of multiple small wires twisted together, which allows for greater flexibility as compared to solid conductors. This flexibility is especially beneficial in applications where the wires need to be routed through tight spaces or subjected to movement, such as in commercial installations or when connecting to equipment that experiences vibrations.

For larger sizes, like those above 8 AWG, the increased flexibility of stranded conductors makes them easier to handle and install in various configurations. Generally, solid conductors are more commonly used in smaller gauges because they can be more economical and easier to terminate. However, as the gauge size increases, the tendency shifts toward stranded conductors to accommodate installation challenges encountered in electrical systems.

In conclusion, the expectation for larger conductors to be stranded reflects industry practices aimed at improving installation efficiency and ensuring durability in various applications.
