Kill A Watt EZ P4460 – Testing on a Known Power Consumer

I’m quite pleased, after leaving a single 60 Watt bulb on for nearly 10 days, here are the results from my Kill A Watt EZ P4460.
They confirm that the unit appears to be functioning correctly and that my last couple of posted results are probably accurate.
I was worried that the unit was under reporting.


Elapsed time: 237 hrs (I left the bulb on continuously for this test)
Measured Consumption (Watts): 60 <– this is what I was a little concerned about.
Measured Consumption (Amps): .5 <– also consistent with what I would expect.
Total Consumption (kWh): 14.6
Cost –
     Actual (for duration of test): $1.55
     Daily: $0.15
     Weekly: $1.08
     Monthly: $4.65
     Annual: $56.64

This puts a concrete dollar value on “we’ll leave a light on for you”. 🙂

One 60 Watt bulb, in my neck of the woods. With power supplied by Georgia Power, just under $57 per year.

Next, I’m hooking it up to my 12 year old Whirlpool refrigerator, I am almost scared to see what I’m paying to keep that running.
