I am continuing to track down my low voltage problem under load. I would guess that my wiring is at least 100 feet that I can see easily. I will try to track it back to the distribution transformer.
When I plug in a 1500W (12.5A if resistive) toaster, my voltage drops by about 2.5V. What range of values can be expected for series impedance and transformer regulation for home power?
