I think I know the answer to this one, but I wanted to check. Using a Clamp-on MM, on a single phase 220VAC, static load, no motor. Attempting to measure actual current usage.
Measure each side and add them together or measure one side and use that?
Measure one side. The opposite side just completes the circuit back to the source.

Exception would be if the equipment does connect to the Neutral and some parts of it run on only one side (115 VAC).

Let's assume they are balanced. If one "leg" says 1 amp, then the total amount used (for both legs attached to the appliance) is 1 amp? And in an hour that is 1 Ah? Even though both legs are pulling the same amount at the same time?
Just checking.
Yes. Think of the 230 VAC line as the secondary of a transformer (which it is). Then, with no Neutral, the currents must be equal.

Okay, yup, yup, yup. I got it now. Thanks, Sam!
