That's a revelation to me.
So, if I size a PVC conduit large enough to slide the pump cord and cord cap through, and
the pump is used for a fountain, that is, Chapter 6 Special Equipment, then the raceway
can become an approved enclosure
After the cord is in, I could plug the male adapters, or bell ends, with duct seal, thus allowing ready removal, and run the PVC from the shrubs at the edge of the stone to the edge of the sump.
