[Homeroast] Quest Amp Question

Further question:

If my line voltage is 125v and I turn my Quest to 10A, doesn't that mean I
am drawing 1250 watts? (don't have a Killowatt)
If so, am I not hurting the unit because it is rated at 1050 watts? I don't
want to burn out the elements.

Just for reference, my Quest will draw only 10.5A empty and cold. I run it
on a 20A (125v measured line voltage) circuit with nothing else running on
that circuit.

Also, I have been doing what Tom does. I set the amperage at a constant
based on the batch size. I typically do a 200g batch with a 7.5A setting
(charge at 200C). However, I have insulated the drum which seems to give the
whole unit a little extra ooomph! (that's a technical word that only
electrical engineers with Ph.D.s use :-)

This afternoon roasts were better. I went back to my origional tools. My
nose and ears. I was trying to be too scientific relying on meters and
guages. It suddenly dawned on me the reason for the meters and guages are to
quantify the art of roasting and replicate a roast. First however, you have
to roast correctly. Now I think I am finally on the right track. This is not
a roaster for a beginner and I was approaching it like a beginner.
