Re: widespread misconception (pig kVA)

The Weather Network once showed, during a heat wave in Toronto when everyone
had their Air Conditioning on, a picture of a pig on a pole, and the
secondary wires were glowing orange hot, and most of the case was
discolored. Somehow this thing kept on working. I don't know what the pig's
rating was, but the current must have been at least a thousand amps.
