I'm not an expert but I've seen some circuit diagrams that explain how a mechanical short can trigger a massive power surge.

Basically the circuit draws unreasonably hard, this might be because you've plugged 4 huge LCD screens into a granny plug.
Then you create a short, and all the draw that was being held up is discharged at once and it causes a massive spike.
While individually all the circuits drawing might be shielded, the wire before them is not.
If you were using a chinkshit board that isn't surge protected a winner could be you.

Again I'm not an expert, so I refrain from fucking around with electricals.
