...I guess those engineers assumed they had been handed over
correctly installed equipment and never thought to check the
relay rating, pity they aren't brightly colour coded. Simulating
real life faults is simply not possible or wise.

Faults don't seem to be the issue. If the line went into overload
protection at a fraction of what it should have done, a simple test
of the line during commissioning (at 50% of rating) would have shown
this.
