Ross, Way off topic now, but from my time programming electrical meters I can tell you pulling the meter from its socket is potentiallyan extremely dangerous thing to do. If there is a load across the meter's poles the spark that results on disconnectcould kill the puller instantly. (You don't want to know what happens if the person isn't killed.) I don't know what property your admin type is trying to protect, but I'm inclined to let it burn and live to work throughthe insurance collection process. Oh, and +1 for timed escalation of a shutdown. Bob Lunney --- On Wed, 2/16/11, Ross J. Reedstrom <reedstrm@rice.edu> wrote: > From: Ross J.
