An air
compressor does not draw full load when it first kicks in (excluding
initial
startup inrush). The current climbs as the pressure in the tank
approaches

I put a Fluke clamp on to my compressor and the reality is it pulls the
most
from about a fourth to half way through bringing up the tank pressure.
This has
to do with the bite of air it gets to compress, When it is close to the
max it
is throttled and doesn't take in much air. That is similar to a vacuum
cleaner
with a plugged hose. It actually runs faster at lower current because
there is
less load.

Ah, a man with actual facts. I do not argue with a man that has a Fluke
clamp on. Interesting! Thanks for the tune up in my linear facts. I forget
that compressors are non-linear beasts.
