What is voltage between earth and line?
In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
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.
Why neutral ground voltage is 120v sometime 0v?
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
What voltage should 208 3 phase leads read?
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
When upsizing wire for voltage drop how much smaller can the neutral wire be the next phase conductor?
The neutral wire should be the same size as your conducters
Should there be voltage between the neutral and ground?
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
Could a neutral wire be powered?
There should be zero voltage between neutral and ground.
What is the reasonable voltage between Neutral?
Between Neutral and Ground should be zero volts. Between Neutral and Hot should be 110 to 120 V in the USA, within the European Union it should be 230 V ± 6%.
What is voltage between earth and line?
In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
How do you determine hot to neutral?
How do you determine what? If you are asking how do you measure the voltage between Hot and Neutral, I suggest a voltmeter. If you are asking how do you differentiate between Hot and Neutral in home wiring, the Hot is Black and Neutral is White.
On a standard three prong AC outlet what should the AC voltage measure between neutral and ground?
Zero, or very close to it. If there is a large neutral current flowing, voltage drop on the neutral leg could cause a volt or so to read between the two. If you read full line voltage, the outlet is wired wrong!
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
On a standard three prong AC outlet what should the AC voltage measure between neutral and hot?
Nominally 120 Volts.
If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?

Why neutral ground voltage is 120v sometime 0v?
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
Why voltage at neutral in ckt is zero?
You really should be asking why the potential of neutral is zero. 'Voltage' means 'potential difference' which, by definition, cannot exist at at point. The reason is that the neutral conductor is earthed (grounded), and earth is, by general consent, considered to have a potential of zero volts. In practise, however, there is usually a small voltage drop between the neutral and earth, so it would be more accurate to say that the neutral's potential is close to zero.
What voltage should 208 3 phase leads read?
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
