The float switch moves with the water level in the tank and determines when the pump turns on and off. In 115V wiring, there are 3 wire legs: 1) Hot 2) Neutral and 3) Ground. The pump will have these 3 wires and the incoming power supply will have these 3 wires. The neutral (white) wire from the panel will connect directly to the neutral (white) wire from the pump. The ground (green) wire from the panel will connect directly to the ground (green) wire from the pump.

This leaves the hot wire from the panel (or 115V Outlet) and the hot wire from the pump. The float switch has two legs. One leg of the float switch will connect to the hot wire from the panel or 115V receptacle/outlet, and the other leg will connect to the hot wire from the pump. (Please note: Most float switches have a white and black wire, which means you will most likely have a white wire to black wire connection. This is normal. Once these connections are made, you may turn the power on, and the submersible pump should operate according to the position of the float switch.
