Pond Boss Forums GENERAL QUESTIONS Help Start amps needed for well pump

We have two deep wells with 1/2 hp 110vac pumps, one at about 90 feet and one at about 80 feet (IIRC wrt depth). Our 5000W/6250W surge generator is marginal at being able to start the pumps. It does fine IF we hook it up to the electrical system near a particular pump's location, but will not do a good job of supplying electric to the pump farthest away (the two wells are about 650 feet of distance, plus wire length within the house and the barn, apart).

IME and IMHO your generator isn't big enough.
