Doing that means it is no longer an isolating transformer!
If floating then touching either secondary wire, or indeed any part of the connected circuit, has little effect because there is no solid path to earth - something that earthing it totally ruins! It only kills you if you touch both wires - something that is also lethal with the mains and is the situation where the RCD just sits and watches you die.
