My grandfather wants to hook up his generator to a well pump but not use a transfer switch at all. He doesnt own a computer so I am here to ask the questions for him. He went out and bought a 5500 watt generator. His well pump runs off a double pole 20 amp breaker. What he was going to do (and actually had started it) was he tied in a pig tail to the well pump with a plug on the end that would connect to a made up extension cord which would plug into the generator. I had told him right from the start that he cant do that because that would back feed the main line as son as the line would come back on. Then he said about how he could just throw that breaker so it wouldnt back feed but I told him thats still illegal. I came up with another idea about putting a safety switch on the line side of the well pump right next to where his pig tail is so its easy to remember to switch it but I still told him thats illegal 100%. He had told me that he didnt want a transfer switch and theres no way he would get one so then I came up with this idea. I told him to cut the line as close to the well pump as possible and install a single outlet 220 volt 20 amp outlet. Then put a short power cord on the well pump which would plug into that outlet. Then get a nema 30L14 plug for the generator end and run either 10/3 or 12/3 extension cord from the generator down to where the well pump is and have a plug end on it that accepts the one on the well pump. What I want to know is if that will be ok to do that? Also is it ok to use a 30amp 240 volt from the generator to power a 20 amp 220 volt well pump?
