1) Affix amp probe around cable, any indication of current means the cable is energized. Amp probes will still indicated current even on a shielded cable because they work off magnetism and magnetism will pass through copper shielding.
The amp probe will also pickup the current in a concentric neutral, summing it with the primary current. You'll get a zero reading on a single phase cable. Cable without current does not mean it's not energized.

2) Strip off the outer PVC jacket layer for about a foot, while in full PPE, down to the shield. Rip off the the shield. Do this without any damage to the insulation below the shield. Now use your tic tracer, if it whines -cable is hot, do not cut. go back to your identification process. If its low tics, cable is de-energized.
Now that the shield is removed, the insulation itself is a shock hazard because the voltage gradient is gone. Center conductor and the surface of the insulation is at the same potential. There is also likely to be a difference in potential between the two shield ends. Do you have a similarly prepared energized cable to test the tracer with? I'd rather be at the end of a shotgun tool using the spiking ground linked above.
