When working with a 3-phase system, can you be in phase and out of rotation at the same time?

In a 3-phase system, being "in phase" typically refers to the phases of the electrical currents being synchronized relative to one another. In contrast, being "out of rotation" describes a situation where the phases are not in the correct sequence, which can lead to inefficient operation or even equipment damage.

In a correctly functioning 3-phase system, the phases must not only be in phase but also maintain the correct rotation sequence (usually designated as ABC or ACB, etc.). If the sequence is altered—meaning the phases are out of rotation—this can cause motors to run in reverse or not operate at all. Therefore, it is not possible to be in phase while simultaneously being out of rotation; both conditions cannot coexist in a standard operational context.

Successful operation of 3-phase equipment relies on both being in phase and the proper rotation sequence. Thus, the assertion that one can be in phase and out of rotation at the same time is fundamentally inaccurate.
