Why do you want to do this anyhow? The information is pretty useless.- Hide quoted text -

Well, I can't argue with you there. For one, I like gadgets. For
another, I have
a 5hp compressor, some computer equipment, a full time window unit,
and
a part time window unit, a bunch of fluorescent lights, occasionally a
hand drill
or table saw.

It all runs on a 30 amp branch circuit and at times the breaker gets
quite
warm to the touch. I thought it would be nice to be able to monitor
the load on the system, i.e., the amps flowing through the feeder
line.

And did I mention I like gadgets?

I'll do some experiments with the one backwards divide by two
method.
