input, and the Y input is connected to the N (Neutral) input. However, for
split-phase or three-phase applications, the X and Y inputs are connected to L1, L2, or
L3 (separate lines). Therefore, for split-phase or three-phase applications, both X and
Y can be electrically hot with respect to the system base (earth reference ground).
shows the physical locations of the X and Y inputs on the system base.

shows a single-phase 120V AC circuit connection. Note that this application
requires a single-pole circuit breaker.
