Not as much as you might think.

superconductors have *three* "critical" values to worry about.

Critical temp: above this they aren't superconducting anymore

Critical current: get more amps than this flowing and it quits being
a superconductor. And a short time later it will explosively
vaporize.

Critical field: If the magnetic field strength exceeds this, it quits
being a superconductor.

When you are running massive amounts of power thru the cable, *any*
of those happening will result in a positive feedback loop as the
cable goes from zero resistance to rather high resistance. which
increases the temp which increases the resistance which...

Like I said, positive feedback loop. With an end result of "Boom" as
the cable explosively vaporizes.
