Where's the live on the secondary of an isolating transformer? If you connect yourself between HT and chassis when the device is powered by via an isolating transformer you'll get a shock, likewise if its powered via an RCD only, an RCD is designed to trip if there's a sufficient difference in current flow between the live and neutral downstream of it such as that provided by a current path to earth.
