What is the difference between 208v and 480V?
What this implies is that the device is designed to operate properly when the voltage drops that low. 208V is *not* the same as 240V. 208V is the voltage between phases of a 3-phase “Y” circuit that is 120V from neutral to any hot. 480V is the voltage between phases of a 3-phase “Y” circuit that’s 277V from hot to neutral.

Can you get 220V from a 208v system?
Neither 110 nor 220 exist as service voltages anywhere that 208 might be a service voltage. The service voltages will be 240 or 208. 120 can be had from either. But, no, you can't get 240V from 208V without a boost transformer.

What is 208 230v single phase?
The text Volts 208/230 Phase 1 means the device will run on either 208 volts or 230 volts (which is nominally 240 volts). In the amps section, the separated numbers (which are the same) are the corresponding value for operation on 208 or 230 volts, respectively.Jul 18, 2014
What is neutral in single-phase?
Neutral is a Zero potential point which do not have any potential. Exactly we can say it as, the perfect ground point is called Neutral point because of each single phase loads needs the current return path.
What is phase neutral?
Neutral is the return path for an AC circuit that carries current in normal condition. This current could be primarily because of the phase current imbalance. The magnitude of this current is a fraction of phase current or in a few cases even double of the phase currents.May 8, 2021
What is the voltage between phase and neutral?
The voltage between the two legs (called phase to phase or line to line) is 240V and the phase to neutral voltage is 120V. The 120/240 notation identifies the phase to neutral voltage followed by the phase to phase voltage.
Does 208v single phase have a neutral? - AskingLot.com
Click to see full answer. Also know, is 208v single phase? When using 120/208V single phase, you will use any two of those same three hot conductors, with the two waveforms peaking 120 degrees apart from each other.When one waveform is at its peak, measuring 120V, the other is only part of way through its cycle, measuring only 88V.
How can 208 be single phase? - Answers
208 is single phase because there are only two conductors involved. There is only one way to look at them, one vs the other.In a three phase system, there are three conductors (delta) or four ...
What is the difference between 208 and 240? | Mike Holt's Forum
An appliance must be marked according to the voltage it is rated (422.60(A)) and connected to the voltage for which it is rated (110.3(B)). To connect a 208V range to a 240V source would be a listing violation, unless the range is marked to be connected to a 240V source as well.
208 vs 220 single phase what's the diff. besides 12Volts?
Thanks for the quick response. So if my transformer says the secondary is 208VAC, then I should be able to get 240VAC from this transformer? The reason I am asking is that my company makes equipment stating an operating voltage of 220 VAC single phase for the main power feeder.
explain 120/208v | Electrician Talk
Hi everyone Thanks in advance for your help If I understand things correctly 120/208v implies the Line voltage (voltage measured between any two line conductors) is 208 volt and the phase voltage (voltage measured between a line an the neutral) is 120 volt. Where does this 208v come from...
What happens when a 208V circuit has no neutral?
In a single phase 208V circuit with no neutral, the two voltage lines are alternating from negative to positive in voltage and they are doing so at opposite times with respect to each other. That is why current flows without a neutral. Click to see full answer.
Do you need a neutral connection for a single phase circuit?
Neutral connections are only needed on single phase circuits. "Why is a neutral not required?". Well, because in three phase, the phases conduct through one another and a dedicated load like a motor uses all three phases and ONLY all three phases. Does 208v need a neutral?
Is 208 a 3 phase?
Dennis Alwon. Most 3 phase systems are 208 but there is a 3 phase delta that is 240V. In terms of the receptacle. They can be straight 208 single phase, 3 phase or single phase 208 with a neutral or 3 phase with a neutral.
Do 208V plugs need a neutral?
Normally the 208v plug will not need a neutral unless it is for a clock or something 120v like a stove. I think it is some sort of appliance like a stove because it is in a food concession area. The 208v plug is similar to the 240v plug in that a neut is not needed.

How many volts does a 3 phase circuit use?
If you start with a three phase, 120/208 volt system, and if you connect a load between two phases, you will get 208 volts to the load, and the neutral wire will not be part of the circuit. Any current that flows from the source via one ungrounded conductor, and passes through the load, will return to the source via the other ungrounded conductor.
Is 208V a return path?
IN a single phase 208v application in most cases no neutral is needed, is there no return path. No one has explained this to me properly. Also is what is refered to as a "common" wire another term for neutral.
Is every neutral a common?
Perhaps every neutral is a common but every common is not a neutral. In my mind, common implies that half the circuit shares the conductor and the other half does not. So I do not see a neutral as a common unless it is a split phase or poly phase system or there is a bus or chassis as the conductor.
