I am monitoring my subpanel with a CT monitor and the utility meter with a Zigby reader.
The meter shows consistently 3% higher. So it is either normal loss in the wire, or the utility is overcharging, or the CT monitor is inaccurate.
The breaker for the sub-panel is 90A.
Could anyone recommend a device with known power draw, so I can use it as a test load to trouble shoot? I could use Kill a Watt, but I am not sure about its precision.
