Q:
I will have the pump running on 230v normally, if power is out due to hurricane etc: I have a 115v generator (30 amp) and will be pluged into outlet on house & run thru generator breaker on breaker panel so will need to switch the j10s from 230v to 115v.
I understand that there is a switch on the pump motor, is moving the switch all that is needed to switch motor from 230v to 115v & that I do not need to move any wires around ?

First and foremost be sure your not back feeding current into the grid that has lost power. You need to isolate your home from the grid before plugging a generator into the home electrical system. Second I don't know how many starting watts your generator has so I'm not sure your generator has enough power to start that pump. Usually a generator that has only 115V available would not be large enough. I would first isolate the pump straight to the generator and see if the generator would start that pump and that will answer your question. Remember that when using a generator, it must be to full speed before the pump is plugged in. If the pump is plugged in while the generator is started, damage to the pump could occur. When changing voltage, it is described on the decal of the pump motor how to make that voltage change. Some motors have a switch, some you have to move a plug-in on back of the motor along with other methods. Not sure which one yours is. If you look at the Grundfos Scala2 115V, its only 550watts. This is a better pump for generator use and will work on your 115V generator.
