My pump is installed 358' down + 15' of wire to the well house, so roughly 375'. I just noticed that they installed 12awg wire. 10awg was what was payed for.
My voltage at the controller box is 244, i've never measured it at anything less than 240 -- the last time I measured current from the pump it was 11.9 amps, so assuming I'm not completely messing up my calculations, that would mean I'd have a 7.4% voltage drop and the voltage at the motor would be about 222v. So the motor voltage would still be within spec.
But are there any other concerns with having that high a percentage drop from the controller to the motor?
My pump was replaced 3 1/2 years ago, it was a crazy time and I wasn't able to check out the installation process as much as I usually would. (I did catch them installing a completely different no-name 1 1/2 hp pump instead of the Grundfos 2HP that was supposed to be installed.)
Part of the problem was that I wasn't the one being billed. It was through a 3rd party insurance company, which took me out of the loop a little bit.
