What Is the Difference Between Romex 12/2 and SOOW 12/2?
There are many differences between Romex® and SOOW cables because they were engineered to fit different applications. Some applications are indoors, some are outdoors, some are underground and some have a large amount of daily impact that the copper will need protection from.
Romex® 12/2 wire is designed with one strand of solid 12 AWG copper while SOOW 12/2 has 65 copper strands in each of the conductors designed specifically for flexibility. Since Romex® is more commonly snaked through walls and conduit it’s much easier for installers to have a stiff cable that holds its form while being pushed up a wall. On the other hand SOOW is a type of portable cord which is the same cable used to build extension cords. Having a flexible extension cord is always a bonus because it helps the coiling and uncoiling process along with carrying it from one location to the next.
