Previously I had little experience with well pumps, but after moving into a home with a failed pump in an area where a shallow pump is at 500', I'm beginning to learn a lot. Recently a pump servicing company pulled up my failed pump, 700' below ground in a 1200' well, and confirmed it had failed at least in part, due to overheating.
My primary concern is that I don't want this to happen again under my watch. I don't expect the installer to honor any warranty even if they do claim it, so I want to make certain the installation complies with the NEC and pump manufacturers specs.
The installed has yet to provide the new pump model but I want to have information before it goes into the ground. The original pump was a 1.5HP PENTAIR 42B0015A2-01 installed in 2019 which so far I have not been able to locate on the manufacturers website. It has a max load of 10.5A with a 10ga wire pigtail. The wire run to it was 700' feet of 8/3 flat cable which has a very thick sheath. I would assume it's some type of direct bury.
What I am looking for is any relevant articles in the NPFA 70 to consider for this type of installation.
