John,

I don't understand your point.

My problem with the power company was a bogus "we can't gain access to
your meter to read it" problem, probably caused by a new meter reader
who was either too lazy to walk the 200 feet back to the meter on the
outside of the lab or didn't bother to turn his head 90 degrees to the
right from the house meter to even see the lab. That's why they tacked
on the $100 charge. They never had any problems reading the meter in the
previous 10+ years and the meter has been in the same place since my lab
was built!

I also wondered how well protected against EMI the new electronic
digital meters are.

My magnifier only draws 12 to 13 KW out of a possible 48 KW supplied to
the lab, which is not an unusual load.
