Curious as to wire a 2 speed 220 pump correctly. My main concern is does a wire go to the neutral buss in the sub-panel?
Hayward 2 speed tristar has 3 wires, black (high), red (low), and white. I ran white to one of the 220 power, and black/red to the other power led via a switch. I also ran a wire(green) from the pump grind to the panels ground buss
Do a need a forth wire? I thought a wire went to the neutral buss in the sub-panel. I thought it was needed for GFI. I am I missing something?
I also wired the heat pump with only 3 wires, 2 power and (1) ground.
I am just setting things up and will have an electrian go tru it before I turn the juice on.
