I have been called into a renovation job. There is a submersible well pump served via a 3-wire. Black, Red, Green. There is not the normal residential 4 wire to the typical franklin control ( yellow being inculded for the start cap).
On arrival, the GC had an extention cord (120V) plugged into the 12-2 which was cut from the holding tank. He claims the pump ran.
some motors will run on any voltage
MY Q is, how do i determine the voltage of this pump?
Do some submersibles not need a cap? , or have intergral ones?
