The electrical line from my water well pump control box to the well was cut and we lost all water pressure, repaired line and I still have no water is there a reset on the square d pressure switch. I have power 240 coming out of the control box but not to the well no other cuts in line.

The reset on a square d switch (lever on the side) is a feature not on all of them. It is there to cut off the switch if the pressure drops 10# or more below the cut in pressure. It does this to protect the pump from running dry. If you have this lever, pull it to reset the switch. However, it sounds like you have power at the control box (not sure what that is) and not at the switch, then you still have a problem upline between the switch and the breaker. Am assuming you have reset breakers and that you had power at the repaired splice in the wire.

This site shows how to reset your switch.
