Water is condensing on the outside of the duct, because the air moving through the duct is much colder than the air in the attic. This normally happens in the summertime, when the air conditioning is blowing cold air through the ductwork, and the air in the attic is hot.

This can happen through convection, or through negative pressurization. check to see if you can feel air being drawn through the return in the house while the fan is off. The easiest way is to hold a piece of paper next to the return and see if
