What is the function of submersible pump cable in a well water system?

Boshart's submersible pump cable is used to supply power to submersible pumps. The pump cable is manufactured to CSA Standard C22.2 No. 75-Thermoplastic Insulated Wires. The cable is available for both two and three wire pumps. Two wire pumps have the starting capacitor built into the submersible motor, and their installations use BLACK-RED-GREEN pump cable (two conductors plus a ground). Three wire installations use BLACK-RED-YELLOW-GREEN pump cable (three conductors plus a ground). Three wire pumps do not have a capacitor built into the motor and require a control box, typically found in the pump house at the well head.
