This reminds me of the time I visited the John Deere
foundry in Waterloo, IA.  They had an arc furnace with
graphite rods the size of small utility poles.  I
remember the meters indicating 50,000 amps at 208 volts.

Anyway, they told me that they had to call the power company
and get permission before turning this thing on, or
it might stall the generator.  One time they forgot
to call, and got fined $10,000 or something like that.
