I've come across quite a few underground pool pump & light ridgid installations that were correctely wrapped but had rusted out anyway and eventually caused the wires to either short and/or open, and the pool pump quit in residential homes. Usually takes 5 to 10 years.

No matter how well you wrap it, I think water gets through over time. The soil here in AZ is acidic too.
