I recall making a simple amp meter years ago by wrapping a strand of wire around the line and hooking it to a voltmeter. It's just a crude transformer. But that was only a few amps, I'd like to make a larger one to measure 200A. Meter CT's for that size are expensive, anyone have a lead on how to make your own? Does your power meter have the flat aluminum disk with the black mark of it that can be seen spinning faster & faster with more load? If yes, I can tell you how to use it to measure what you want, excepting pf?

I would interested in how you can measure the draw,if not too much trouble?
