Phase 2 testing is a crucial stage in clinical trials that evaluates the efficacy and side effects of a drug or treatment in a larger group of participants, typically ranging from 100 to 300 individuals. This phase aims to determine whether the treatment is effective for a specific condition and to further assess its safety profile. It follows successful Phase 1 trials, which primarily focus on safety and dosage. Phase 2 results help inform the decision to advance to Phase 3 trials, where the treatment is tested in a larger population.
I depends on what you are connecting to it but you only need 1 of the phases providing you can get to a neutral
Quadrature phase occurs when two periodic waveforms have a phase difference of 1/4 of their output period.

No. If you have phase 1, 2, 3 (in that order), and phase 1 is the highest voltage at the instant a switching event occurs (causing a power surge), the surge voltage will be highest in phase 1. For polarity to change, you would need phase 2 to instantaneously change to greater than 1, which will not happen.
