Hi and thanks for a wonderful and inspiring site. I notice that you are using one clamp only, and there's another site using two clamps (http://www.picobay.com/projects/2009/01/real-time-web-based-power-charti...). I am thinking of monitoring the power use in my home, and clamping the device(s) at the mains intake (before the breakers). I live in Norway, using 240V 50Hz. Is one clamp enough? I am struggling a little with the theory here. And I think I will try without the phase changes in the first place (although we use the washing machine constantly...), but could I measure the voltage in one outlet instead of in the breaker box?
