False. For AC power (50/60 Hz), skin effect is negligible at typical sizes (< 250 kcmil). A 10 AWG solid and 10 AWG stranded have the same ampacity. Stranded is just easier to bend. copper cable sizing

In the modern world, electricity flows like blood through a circulatory system. But unlike veins and arteries, which are fixed in size, the copper cables in our buildings, factories, and renewable energy systems are designed by human choice. And that choice—choosing the right thickness of copper—is far more nuanced than "the thicker, the better." Note: Always verify with local codes and actual
