Yes, GFI circuits often start with the GFI and connected in parallel beyond 2 or 3 outlets in RV's. They are mandated to be installed within reach of water. Therefore Kitchens low and high installs, baths and outside receps are required to be protected by GFI outlets or sometimes panel circuit breakers are installed for the above locations. If the GFI goes down, all circuits downstream will also open.
