the kill-a-watt I have is showing at 1115 Watts at the wall.  Since just moving the box it has been shutting off quickly.  The only other thing that I have done is update the firmware a while back and have it set at 196M and 725 Volts.  I have a 18 gauge computer cable that showed some wear on one of the terminals.  I ordered a 14 gauge cable to replace it.  There's some dust inside, but other than that I'm not sure what is going on.  Anyone have this problem.  I'm close to retiring it anyway, but would still like to know if it works fine (and safe) until I shut it off completely.
