The unit worked fine when performing testing the power consumption of a device for a limited amount of time. However, I ran into a problem when was using the Kill A Watt to test or monitor the power used on a device for an extended period of time. The unit is rated at 1875 watts ( Max Current 15 Amp and Max Voltage if 125 VAC )
In my particular case the receptacle on the Kill A Watt began to melt and turn brown when attached to a device that draws about 1,311 watts (117 Volts at 11.5 Amps ) which is below the maximum ratings of the Kill O Watt.
