Tony,

It seems you need some help here. If you were in the military, for the US or
one of our allies... Thank You.

Looks like you're coming from Canada, so you may have some trouble
understanding what I'm saying.

Please feel free to e-mail me off list and I'll be happy to continue this
discussion further.

Jake

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.

Hi,
I don't think so. Look at a motor for an example. Does it show start
surge current? You said absolute highest.
I am military background. Most of my life I wokred on mil-spec stuffs.
Quite different from commercial ones.
Tony


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.
