I have personlally removed whiskers from tin plated metal pots on Basler power supply regulators that were upwards of 3/8" in length and about 30 or 32 ga in diameter, more than enough to carry a sizable current. I had another board that had a hole in it from a short, suspected a whisker but the proof had poofed, although the pots looked like they had mold growing on them. The boards were 35 or so years old.

That's quite a bit of amperage for a 1-2 micron whisker, I didn't know they were that hearty.
