In a triple-phase electrical grid, how many phases, or hots, are there?

Explanation:
Triple-phase means three separate alternating current waveforms that are offset in time, specifically 120 degrees apart. That setup uses three hot conductors, one for each phase. So in a three-phase system there are three phases, or three hots. (A neutral conductor may also be present in many installations, but the number of phases itself is three.) This arrangement provides smoother power delivery and better motor performance than a single-phase setup.
