Hi. I recently purchased and installed on of your B014W3D1OC meters (volt, amp, power, power used) for AC up to 100A.

I wired it up to a 220V panel to neutral and 1 leg for voltage, and then ran one leg thru the current ring one direction and the second leg the opposite direction.
In essence this should tell me my 110V amps. ie if I used the stove at 15 ampsx220 it would read 30 amps 110. It appears to be working this way, however the power number doesn’t seem to correspond.

I would think 30×110 would be 3300 watts, or 30×120 would be 3600- and after an hour of being on at a constant draw would read 3.3 or 3.6 kw/h. The meter seems to read it at 2200, or 2800, but not where it “should” be. Different amperages give different numbers (1 amp is 75 watts, whereas 8 reads 850) Can you explain this? Is it how I wired it, is the product defective, or is the power calculation more complicated than I think?

Thanks in advance,

your customer
