No doubt

Don't know what you mean here. You mean reflected power by inductive loads,
so the current read by a typical meter is higher than the actual current?

I might, depending on what liability issues I have to deal with.

I don't know what you're refering to, and the list search engine is too
scary for me to attempt a search. Can you mail me Dave's spec's?
