I have a friend who is wiring his panel to work with his generator (using a transfer switch). The generator is a Yamaha 4000 watt (4600 surge), and the well pump is 1 &1/2 horsepower (around 1200 watts?) My concern is with startup watts; I'm personally unfamiliar with how well pumps run with generators, will this likely work? Or is there no way to tell without hooking it up?
