This depends on your service voltage and whether you have any step down Transformers in the building. The only way to know is to check yourself. Use a voltmeter or multimeter, with one lead on L1 terminal and one lead on Neutral terminal. Set the meter to read AC volts, with a range of at least 300 volts (your reading should either be 277 or 120.) The safest way to do this is to deenergize the circuit, place your leads, and then re-energize the circuit without touching anything. You should be able to get a reading without touching anything at all.

In a 220 volt AC single phase circuit the voltage from either leg to the neutral is?
The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and as you know from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get 240 outputs because L1 and L2 are adjacent to one another.
How does a 3-phase 115 volt power supply measure 200 volts in-between each phase?
You should have about 230 volts between any pair of 3-phase service legs: L1-L2, L2-L3, L3-L1. If the voltage measured between any one pair results in low or no voltage, then you have a fuse or circuit problem.
Voltage across Neutral and earth for a 3 phase auto transformer?
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
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.
What is a line to line voltage?
In a 3 phase system, the voltage measured between any two phase is called line to line voltage.And the voltage measured between line to neutral is called phase to neutral (line to neutral) voltage.AnswerThere is no such thing as a 'phase-to-phase' or a 'phase-to-neutral' voltage. The correct terms are 'line-to-line' and 'line-to-neutral'.The voltage between any two line conductors is called a line voltage.In a three-phase, three-wire, system, the line voltage is numerically equal to the phase voltage.In a three-phase, four-wire, system, the voltage between any line conductor and the neutral conductor is called a phase voltage. The line voltage is 1.732 times larger than the phase voltage.
What voltage would be measured from any phase to ground on a 480 volt 3 phase wye system?
A voltage of 277 is the line to neutral (ground) voltage of a 480 volt wye three phase system. L1- N, L2 - N and L3 - N will give you 277 volts. L1 to L2. L2 to L3 and L3 to L1 will give you 480 volts.
208 volt 12 amps versus 277 volt 6 amps?
It is hard to see a question here. Both of these voltages are currently use in electrical systems today. Both voltages are related to three phase systems. A voltage of 208 volts is a three phase wye system that has a voltage of 208 between lines L1, L2 and L3 and 120 volts between any of the lines and neutral. A voltage of 277 is the line to neutral voltage of a 480 volt three phase wye system. There is a voltage of 480 between L1, L2 and L3 and 277 volts between any of the lines and neutral.
How do you connect a 115 v circuit when only a 230 v location is available?
Usually in a 230 volt situation, there are three wires. One wire is called neutral or ground. When you hook a motor or lamp between one wire and neutral, you get 115 volts. They are designated usually as L1, L2 and neutral. Things hooked between L1 and L2 are at 230 volts. Anything between L1 and neutral or L2 and neutral are at 120 volts.
In a 220 volt AC single phase circuit the voltage from either leg to the neutral is?
The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The voltage measurement from the L1 to N will give you 120 volts.

A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
Could a neutral wire be powered?
There should be zero voltage between neutral and ground.
How do you get line voltage from a single phase 3 wire system?
Answer for USA, Canada and countries running a 60 Hz supply service.A three wire system uses two lines L1 and L2 and a Neutral. You can obtain a 120 volt potential from L1 to N or 120 volt potential from L2 to N. Between L1 and L2 you can obtain a potential of 240 volts.
Should voltage going into home be 250V?
Its a bit on the high side, as measured between L1 and L2, but not a problem. Better for appliances than a low voltage. Lights will tend to be a just bit brighter and use a bit above rated power. Certainly a big problem if measured between either live conductors and the neutral.
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 create 120V from 240V 3 wire L1 L2 G in a residential system?
The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The 120 voltage is already there to use in a residential system. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and as you know from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get 240 outputs because L1 and L2 are adjacent to one another.
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.
