Electrical costs for my pool

>just make sure it stays constant when you run the test

Yes, that is my issue. I have 5 refridgerators of varying sizes, some compact, under counter, etc. 2 AC units, freezer in the garage etc. I would need to shut them all down. And then monitor the usage over some time like a half hour correct and see what the difference is in KWhr ? My electric meter has a little wheel that spins like crazy, then 5 dials that directly show the KWhr used. If I monitor that over a half hour or hours time it could tell me the difference roughly as it's hard to tell half dial increments, etc.

If you use the horizontal wheel that spins very quickly as I suggested in my earlier post, you should not need to run the test more than five minutes. The pump uses enough power probably to give you 10 rotations in less than 2 miniutes. Without the pump, the rotations are so slow that one rotation should suffice. Time with and without the pump and use the formula I posted earlier. It is very easy to do. The other dials are not fine enough resolution to use effectively in a short period of time.
