#9 and #10 are absolutely confused :D
Secondary in a CT usually has a very High voltage (Primary= 1 Turn; Secondary= Many many Turns).
That`s why, if u leave Secondary open when the CT is Offline, a large voltage build up on the open Secondary causes a failure of its Insulation on Secondary, and renders the CT unoperational/BLOWN !!
