I am ruuning power to a shower building at a camp. Exactly 8' away is another building (restrooms) that need power as well. I am mounting a 3R subpanel on the exterior of the shower building, on the wall facing the restrooms. Is it sufficient to use this subpanel as the disconnecting means for the restroom building, or should they get their own subpanel as well? There will be 3 circuits going into the restrooms. I know that I have to ground the piping + a ground rod at both of the buildings, however, it makes little sense to put up 2 subpanels 8' apart, when one will have more than enough capacity to serve both buildings.
Is 230.70 the right section to be reading for feeds to outbuildings? It says services, but I seem to remember part of the code referring me back to 230.70 when dealing with disconects on seperate structures.
Any help is apreciated!
