Which leg is 208 on 3 phase power?
On three phase 208 volts one leg does not have the potential of 208 volts. It takes two legs to provide the 208 volts. The potential is across AB, BC and CA. Voltage to the grounded neutral A-N, B-N and C-N will produce a potential of 120 volts. In a wye configured secondary three phase four wire you have the potential of 120/208 volts.
Are single phase 208v and single phase 230v equivalent?
No, not really. 208V is derived from two phases of a 208/120 three phase power system, while 230V (or 240) is a single-phase power system already. Motors and other loads are usually notrated for both voltages, and could be damaged if fed the wrong one. Of course, other devices are rated for both. If so, it will be listed on the nameplate.
45 kva at 208 120 volts amp load?
I am assuming that you are talking single phase. 45 kva is k = 1000, v = volts, a = amps. 45 kva is 45000 volt / amps. Input 45000 divided by 208 volts = 216 amps. Output 45000 divided by 120 volts = 375 amps. There are other losses in the transformer but as a general rule of thumb this is the calculation that you would use.
Will 120 - 277 volt electronic fluorescent ballasts work on 208 volts?
NO! a 120-277 electronic ballast requires one "hot" wire and a neutral from either a 110V or 277V supply. If you supply it with two "hot" wires from a 208 V supply, it will instantly burn up.Yes. A ballast with a specification range of 120 volt to 277 volt will work on 208 volt. These ballast use intelligent voltage sensing technology and it does not matter if the source is a hot and neutral or two (2) hots. Don't believe it? Call a ballast manufacturer instead of giving incorrect answers.
What percentage is 150 volts 0f 120 volts?
150 volts is 125% of 120 volts.
How does 120 volts come from 208 volts?
208 is a three phase wye connection voltage. To obtain the each individual coil voltage the 208 is divided by 1.73 which equals to 120 volts. Hence you have 3 phase 208 voltage on the phase legs and 120 volts to the wye point which is grounded. This same formula is used on any 3 phase system. 600/347, 480/277, 208/120.
How will a 3 phase panel give you 110 volts and 220 volts?
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.
What is the standard voltage?
In the USA it is usually 120/208 or 120/240 volts In Europe I think it's 220 volts

How many volts are supplied to the average household?
In the USA it is either 120/208 or 120/240 depending on your local unility company
How do you convert 230v to 208 volts single phase?
A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give you 120 volts.
How do you create a common lead from 3 phase 120 volt?
If you are referring a common lead as meaning a neutral of a three phase system, the three phase voltage has to be 208 volts. This type of connection is in a wye configuration. It is found by this formula 208/1.73 = 120 volts. This connection will supply 120 volts between any one of the three supply legs and the grounded neutral.
How many volts in 3 phase?
It starts out with 480 Volts, which is used to power motors. 480 can be stepped down to 120/208/277. The 120 operates normal appliances, while 208 can be used for dryers and welders rated for 208. 277V is usually used for lighting circuits. 3-Phase is used in commercial and industrial settings.
What is a 208 circuit?
The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases. 208 circuit would consist of two phases of a 208 volt wye system or could be all three phases. The voltage between conductors would be 208 volts. The voltage to ground from any phase would be 120 volts. A 240 volt delta system would give you a high leg to ground, somewhere around 190 volts and the other two would be 120 volts to ground.
Are single phase 208v and single phase 230v equivalent?
No, not really. 208V is derived from two phases of a 208/120 three phase power system, while 230V (or 240) is a single-phase power system already.

What is 50 percent of 120 volts?
50% of 120 volts = 50% * 120 = 0.5 * 120 = 60 volts
