Most mixers have a so called "phase reverse button" but it's not a "phase" button, it's the "polarity reverse" button in each channel. It's real simple, to reverse the polarity on a mic, you simply reverse the pin wires 2 an 3.
Phase means time shifting. Polarity reversion means changing cable a and b.
That are really different things.
Scroll down to related links and look at "Polarity reversal is not phase shifting".
This answer has nothing to do with phase: To reverse the rotation on a three phase motor you simply swap any two of the three motor leads
Also called reverse polarity. === === Commonly noticed during a home inspection prior to purchase or sale. This means when you test a receptacle, the hot slot is connected to neutral and the neutral slot is connected to hot. You need to make sure that your hot wires and neutral wires are connected to the proper terminals (hot to brass, neutral to silver). If this applies to many receptacles in an area, it's usually a matter of finding and fixing the first one. If this applies to one or two receptacles, it's easy to fix them. To correct this, shut off the breaker for the circuit in question and test it to verify it is off. Remove the receptacle and verify the white wires are on the silver screws and the black, red, or blue colors are on the brass screws. If this is done your polarity will be correct.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
How does a phase leg connect to a neutral in an electrical circuit?
A phase leg connects to the neutral through the connected load.
Why neutral is not requied in 3 phase?
As far as I understand, you don't need neutral line for connecting appliances that is 3-phase compilant. You only need the neutral line to connect a single phase appliance, which you connect along with one of the three lines.
What is the voltage for each leg on a 480v 3-phase pannel phase to neutral?
Only one neutral conductor is typically in a 3 phase panel.
Do you need a neutral to install 480 volts 3 phase heater?
If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.

When phase and neutral will short means what will be the voltage in neutral?
If the phase and neutral wires are shorted together, the voltage in the neutral wire will be the same as the phase voltage. This is because the short circuit effectively bypasses any impedance or resistance in the circuit, causing the potential difference between the phase and neutral wires to be equal.
What is phase reversal in AC what are conditions for phase reversal in AC.?
I understand that when generating energy 3 Phases energy it is purposely generated at 90º phase lag. If one of the phases fails to lag and catches the other in frequency, the phases become same as one.

What is the code ruling in the US on 3 phase branch circuits and the neutral?
A three phase system will have 3 phase branch circuits and no neutral.
What happens when phase to phase line is connected?
If there is a voltage differential from phase to phase, and a conductance (inverse of resistance) between them, then current (amperes) flows. This is no different than phase to neutral, i.e. voltage across conductance generates current, (I = EC, or I = E/A) except that neutral current is zero in a true phase to phase connection.Note that phase angle is always relative. In phase to neutral, it is relative to (typically) neutral; while in phase to phase, it is relative to the other phase. By Fourier Analysis, the difference between two phases of the same frequency, but of different phase angles, is still a sine (or cosine) wave. Also, by Kirchoff's Current Law, (implied, and I will (sort of) not repeat it here), current entering from one phase and equally leaving via another phase will not reflect at all in the neutral conductor.The simple answer is that connecting phase to phase is a short circuit, just like connecting phase to neutral.CommentThere is no such thing as 'phase to phase' or 'phase to neutral'. The correct terms are 'line to line' and 'line to neutral'.

Why the neutral cable takes high current than the phase lines in three phase installation?
In a balanced three-phase system, the current in the neutral wire should ideally be minimal as the three phase conductors carry equal and opposite currents that cancel out in the neutral wire. However, if the loads are unbalanced, the neutral wire may have higher current due to the uneven distribution of power among the phases. This can happen when loads on each phase are different or when single-phase loads are connected between a phase and neutral, leading to increased neutral current.
What is the power line voltage between phase and earthing?
It is the same as phase to neutral. As the neutral is earthed at the electricity suppliers transformer.
What would be the effect on the neutral bar of a 3 phase D B if the main incoming neutral is lost?
A three phase delta system does not use a neutral in its operation.
