Sorry for my ignorance on this subject but I need to ask so I can feel safe before allowing work to proceed. I have a need to replace the wiring from my breaker panel to my pump and pool light. The old wiring is buried in conduit and , without a ridiculous amount of work can't be removed. Can the old wiring just be disconnected and left buried and new wiring installed? My concern is, by eliminating the old wiring, am I eliminating something else necessary to the "electrical safety" of the pool, like would the bonding sytem somehow be tied into the old wiring?
