It looks like it's a 20A version, but you should be able to change the coil and go to 30A. They say it is not calibrated but gives in the 3% range for accuracy, which is about what I would expect. If I were serious, I would calibrate each one in its final location against a very good ammeter. I will add the disclaimer that mixing low voltage wiring and high voltage AC is a risk. If you are not competent around mains AC , don't do this yourselves. Just putting this in a breaker panel as is would likely break building codes. jerry On 02/08/2014 07:24 AM, Daniel MacKay wrote: > Hello all! > > Does anyone have an inexpensive (say, under $50 type of thing) 1-Wire AC amp > (clamp type, obviously) sensor solution? > > I need to measure common household amps - so up to, say 30A would be fine, > say, with 0.5A accuracy (or so.) > > Any thoughts would be welcome. > > -dan > ------------------------------------------------------------------------------ > Managing the Performance of Cloud-Based Applications > Take advantage of what the Cloud has to offer - Avoid Common Pitfalls. > Read the Whitepaper. > http://pubads.g.doubleclick.net/gampad/clk?id=121051231&iu=/4140/ostg.clktrk > _______________________________________________ > Owfs-developers mailing list > Owfs-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/owfs-developers ------------------------------------------------------------------------------ Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.
