2 Wire SS Submersible Pump Assembly |
Note: 1PH only. The ground wire is not counted as a wire and is why 2 wire pump assemblies contain 3 wires.
Franklin 2 wire pump assemblies have 2 black wires (line 1 & line 2) and 1 green ground wire in the harness on the Franklin submersible motor. A 2 wire submersible motor does not require a control box to operate and are used for smaller submersible motors up to 1-1/2HP. This requires 1 less wire in the well to the submersible motor saving money for wire. The 2 wire motors have had a great track record for several years and is the recommended pump assembly for most residential applications.
Some people years ago believed the ground was not necessary and did not install one to the pump. When you have only three wires at the top of the well that is no guarantee its a 2 wire pump, the ground may not have been installed on the 3 wire pump. If you have a control box the wires to the pump come from then its not a 2 wire pump assembly. Remember, well wire may not be the same color where those wires attach to the submersible motor.
