Most of my electric bill comes from use of lighting. However, soon I
will hook up a 10 HP Quincy reciprocating compressor, and I am
concerned about demand billing.

Do I understand it correctly that

a) A soft start can reduce inrush current
b) A reciprocating compressor with unloaders can be started by a soft
start?

Thanks

The plant air compressor is a high volume, 4 cylinder, 60 gallon Quincy
with a 3 phase 208 volt motor. The compressor itself is a "V" with two
cylinders on each bank. Both banks feed a common tube going to the tank.
It pumps up to 125PSI. The HP is not listed on the motor. It does not
trigger a demand reading on the meter.

So you should be good, also.

Yep. If memory serves, demand must be constant for at least 15 minutes.
That, or course, could vary from one jurisdiction to another. In rush for
starting motors is expected.
