True, without a load on the CT secondaries they may even explode. This was discussed in detail in a previous thread. Shorting out the secodaries eliminates the problem, unless someone removes the jumpers. If you are that concerned, make up crimp splices to "piece together" the lines.
BTW,
I've had CTs for motor load monitoring that were supposed to go to a recording device, shorted out for years with no problem.
