120V 240V Electricity - Split phase 3 wire electrician

In electricity and electronics, the word phase is used in different contexts, all relating to alternating electric currents.

In electricity, the word phase designates the “channels” of the same source of alternating power, between which there is a phase shift (two at 180 ° in single-phase and three at 120 ° in three-phase).

By assimilation, low voltage electricians also use the word "phase" to designate the active conductor (s) of an AC power supply. In domestic installations, the conductor is normally wired with a bright colored wire (red, orange). In general, it is the wire (s) N 1 conductors, which are called phase wires, on which the presence of an alternating electric voltage can be demonstrated with a "phase tester".

In electronics, we speak of phase shift when there is an angular shift between sinusoidal signals, detected by an oscilloscope. If the passage through the zero value as well as the maximum value is simultaneous, we say that they are in phase.
