and small appliances are connected between one line and the neutral, providing 120 V. Higher-demand appliances such as ovens, dryers, or water heaters are powered by 240 V circuits, connected between the two 120 V lines. These 240 V loads are either hard-wired or use outlets designed to be non-interchangeable with 120 V outlets.

Split-phase systems are also used in some specialized applications to reduce the risk of electric shock or to minimize electromagnetic noise.
