Understanding your century pool pump wiring diagram is the key to a safe and functional pool system. Whether you are installing a new AO Smith Century motor or replacing an old one, getting the electrical connections right prevents motor burnout and hazardous shorts. Safety First: Kill the Power
: Older models may require moving a specific internal wire (often white or brown) or a "voltage change plug" to a different terminal to switch from series (230V) to parallel (115V) winding configurations. 3. Connect Power and Ground
Before touching any wires, turn off the power at the main breaker panel and the local timer box. Use a non-contact voltage tester to confirm the lines are dead. Water and electricity are a lethal combination; never work on a pump while standing in a puddle. Identifying Your Voltage: 115V vs. 230V
