I have a question regarding the common household service entrance power
meters.  I have a non-ratcheting type meter.  When I kill the main circuit
breaker the meter still creeps along at about 1 centimeter in about 8 or 9
seconds.  I have confirmed that there is no power to any circuit that is
available to my dwelling.  I know meters consume a very small amount of
power, but I have experimented with power consumption metering in the past
in various apartments that I have lived in over the years and i've never
seen one turn "so fast" when the main circuit has been shut off.  Is this
normal?  Usually they come to a near dead stop.

    You may have more than one breaker panel hooked directly into the
meter.  Perhaps a second refrigerator located in a garage.

Your meter wheel is graduated in 100's.  
    How long does it take to make one complete revolution..
    Time it with a watch..   What is the calibration number printed on
meter.   see..

Your sure that you killed the main?  gotta ask.

Call your utility and ask them to check the meter. I have seen 4 bad in 30
years. There should be no movement of the meter in the off position
