Which flexible cord is permitted to be immersed in water for powering a permanently installed fountain?

Type SO
Type SOW
Type SJO
Type SJOW

The correct answer is: Type SOW

The correct choice, Type SOW, is specifically designed for outdoor use and is rated for wet locations. This makes it suitable for applications where the cord may be immersed in water, such as powering a fountain that is permanently installed. Type SOW cables have a heavy-duty construction, including insulation that can withstand moisture and a high level of durability against environmental conditions. This is critical for safety and performance when electricity is involved in water features. While other types like Type SO have some moisture resistance, they are generally not rated for continuous immersion in water, which is a key requirement for the application in question. Types SJO and SJOW, while they offer flexibility and can handle some moisture, do not have the specific rating for continuous wet use as Type SOW does.
