So here is the issue I've been having: I bought the house 5.5 years ago, it was built about 6.5 years ago. My well is 76 feet, it had a 1/2HP 110V 8.5A continuous draw submersible pump without a control box. A few years ago, the 2oA 110V and the 30A on the main 220V panel would randomly trip (sometimes only 1, usually both). We had an electrician from a reputable company out who checked the wiring from the house to the well and then blamed the pump. The well installer came out and he blamed the electric cabling from the house to the well. The pump would occasionally draw 30A upon startup and trip the breakers (measured on an ammeter). Over the xmas holiday when I had some help, we replaced the well pump with a 1HP 110V 11A draw pump. It worked well for about 5 days and then the breaker tripped again. I haven't really gotten to do any more troubleshooting as I have gone out of town for business. Is it possible that a problem with wiring from the house to the well could cause the pump to draw more amps (a small intermittent short or exposed wiring)? The wire is about 18 inches down in the ground (which I found when I had to fix a line breakage where the well supply hose met the house piping), and I really don't want to replace it all, but I will (inside conduit this time). Just asking for ideas. This is pretty much the last thing I can think of since I've changed the breakers, the pressure switch and the pump. It just didn't seem to make any sense to me.
