How do you covert 120 volts to 208 volts?
Single phase or three phase? 120/208 would be measured hot to ground for 120 and hot to hot (phase to phase) for the 208 reading. Any hot to ground will read 120 and any two phases together will read 208.
Why am I only getting 120 volts from a 30 amp breaker that should be feeding 220 volts?
I assume you have a 30 amp two pole 220 volts breaker. Check the voltage source. If the source voltage is 220V, but out let voltage is 120 then the breaker must be faulty, a high resistance or partial open circuit could have caused the reduced voltage at the breaker outlet.
Can you read 120 volts line to neutral even with a severed neutral?
It depends on what side of the break that you are reading from. On the neutral load side of the break there will be no reading. On the panel neutral side of the break you will get a reading.
Why on 120 volt circuit both black and neutral read 120 volts?
Improperly wired outlet, loose/improper neutral or problem with incoming power. I advise you talk with a licensed electrician as it most likely will need to involve opening your breaker box to properly diagnose problem. There will be serious safety issues when doing this.
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
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.

What is the voltage between neutral and earth if neutral is broken?
Normally, it is zero.Except in very special cases, the neutral and ground (earth) conductors in a building are tied together at one point in the system, so ideally the voltage difference would be zero. The reason that it might not be zero is there is current flowing in the neutral and, thus, voltage drop in the neutral conductor. Since the ground conductor normally never has current flow (unless there is a fault), there will be a difference in voltage equal to the voltage drop across the neutral conductor, which varies with load (current).It should be 0V , but as per our earth pit maintaining that voltage will be varied even also not exceed 5V.
When trouble shooting a single pahse 208 volt hid ballast with your voltmeter you read 120 volts to ground on each phase wire but 0 volts across the phase wires what is wrong?
Sounds like both phase wires are connected to the same phase.

How to measure volts accurately in an electrical circuit?
To measure volts accurately in an electrical circuit, use a digital multimeter set to the voltage range needed. Connect the multimeter probes to the circuit's positive and negative terminals. Read the voltage displayed on the multimeter screen for an accurate measurement.
What would you read if you connect two phases of a wye electrical connection together between phase and neutral?
I think you probably mean 'lines', rather than 'phases' but, even so, your question is still confusing. However, if you connect any two lines together directly, you will create a line-to-line short circuit fault; if you connect any line and neutral together directly, you will create a line-to-neutral short circuit fault.
How to read volts on a multimeter?
To read volts on a multimeter, set the dial to the voltage setting, typically labeled as "V" or "VDC." Connect the red probe to the positive terminal and the black probe to the negative terminal of the circuit or component you want to measure. The display will show the voltage reading in volts.
How do you convert a 3 phase power supply to a single phase supply?
If the 3 phase circuit has a neutral (4th) wire, you can connect from one of the 3 phase wires to the neutral wire for a single phase circuit. You need to check the voltage with a DVM voltmeter or equivalent to make sure the 3 phase circuit is the correct voltage from one leg (wire) to the neutral for the equipment you wish to power. Be careful with this one as it may exceed your capabilities to do this work safely.Another answerYou don't need to "convert" a three phase service to a single phase service, you only need to take a single phase service from one of the lines of a three phase service.Working with a 3-phase electrical service is not a safe DIY project to be attempted by anyone who has not had the proper training and practical experience of working with high voltage electrical services. So, if you needed to ask this question, you should not be attempting to do this work by yourself!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 YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
