Thanks,that's what I was prety much looking for. I had tried my previous searches with kill-a-watt always in the text.
The eum-2000 etc looks like it should work.
A look through the Electrosonic cataloge did show an abundance or 0-120V and 0-5 amp meters plus the appropriate CT's and PT's, frequency meters and KW hr meters. The cost of each little part was going to add up beyond a factory built data unit.
