Short answer: YES
Long answer: That is very likely the best way to do it, Measure at the breaker box with everything on, Or a plug in meter into an outlet.
The Kill-a-watt is a very useful meter.. Some functions (Frequency, Voltage) only require it be plugged in, (The rest apply only to things plugged into it)
It is rapidly becoming the lowest priced plug-in voltmeter on the market.
