You should be able to run that well pump. I did it once, just cut off extension cord end and connect it in the fuse panel to the wire. It will run the pump for sure. Anything else you want too. lights,plugs,etc... If your gen. is too small to do all at once just unplug it when you are done. I know you can't get hot water from electric water heater but if you have gas you can take a hot shower.
