Distribution switch cabinet
We had a substation (115 kV to 12kV) go down coincident with a fire in a 12 kV switch cabinet down the road a ways. The linemen inspecting the wreckage located the remains of two very well done rats. Theory was that rats could jump onto and off of the bare bus bars with no problems. But when one saw his buddy passing by on an adjacent phase, they decided to touch noses. The resulting arc conducted enough current (and the individual circuit breakers were mis-coordinated) so that the high side fuses blew first and took out several square miles of power downtown.
