Hi,
All I am saying is Volt x Amp is comprised of resistive Watts which is
producing work and reactive Watts which is wasted. Ratio of this two is
power factor in another expression. Real world estimation or whatever is
still based on theory. If you don't know theory or ignore it, sooner or
later you get into trouble. Worst case, fire, or getting someone killed.
That someone could be you. I hope not.

Tony, it seems you've got good intentions here, but please remember:

The original question was about efficiency and not safety. UL ratings in the
US rate an appliance at X watts for the absolute possible worst case
scenario. Pf, service inductance, and other factors are used for when you're
trying to squeeze the most out of your energy dollar, or engineering new
equipment. When that nameplate goes on any appliance that's UL listed, rest
assured the current ratings displayed there are the absolute highest that
piece can possibly consume.

BTW, the National Electrical Code dictates that we must provide for that
nameplate rating... plus 20 percent... to make it safe.

I'm certain everything Turtle does is safe, and I'm certain everything I do
is safe. The question was simply about efficiency.

We know theory, and how it's applied in the real world. Apparently you're
mssing that part.
