Does a residential boat house that is 20-30 feet off shore have to have its own ground rod driven in the ground on the shore and a GEC run from the ground rod to the panel on the boat house? Should (2)hots, (1)neutral and (1)equipment ground be run for the service panel to the boat house panel even though its run in PVC(120/240v single phase installation)or just (2)hots and a ground?
Any information relating to residential boat houses would be much appreciated.
