How can you get a 240V single-phase power from a 120V 3-phase service?

First of all there is no common three phase 120 volt service. There is in North America a three wire 120/240 volt single phase service. That being said, if you want to change a 120 volt source to 240 volts it must be done with a transformer. Its classification is a step up transformer. The primary side of the transformer H1 - H2 will be connected to the 120 volts. The secondary side of the transformer X1 - X2 will be connected to the 240 volt load. The transformer is sized by the current required by the 240 volt load.

∙ 8y agoThere is no 120 volt three phase service. The nearest voltage you can get is 208 volts. It is a wye connection which gives you 208 volts between the three legs and 120 volt between any of the three legs and ground. This ground point is the systems neutral point.

Can you install a 120V baseboard heater on 110 amp power service?
Yes. The voltage of 120 volts is a nominal figure. The utility company has a plus or minus tolerance from 110 to 120 volts. This tolerance is based on the figure of 115 volts.
Is 12 volts dc as powerful as 120 volts ac?
You get power by multiplying the amperes and the voltage. 12V, 10A dc would give the same power as 120V, 1A ac.
What can be used to electrically isolate a piece of equipment from the power distribution system?
Assuming you are speaking of a standard 120v AC power, a simple one-to-one isolation transformer is made for this purpose. Be sure power rating is big enough for the load.
Considering 100A 240V service has 2 poles at 100A each is the total usable power actually 200A at 120V?
No, amperage is not additive, but a constant. Think of power as water, its always the same temperature, hot (amps). The pressure is variable (volts). The true answer is undoubtedly more complex, but you get the point. If you need to draw 200 amps you would actually need a 400 amp service because code states you cannot have more than an 80% load on a breaker That's an interesting question and I had to run the theory through my brain a few times to confirm my answer. The answer is if you have a 100A 240V service, you could draw what appears to be 200A from that panel at 120V. If you install 100A 120V single pole breakers on each side of the panel (in reality this would be many breakers but let's keep it simple) then both breakers will operate just fine, giving the appearance of 200A. In reality, however, one breaker actually feeds through to the other breaker. The neutral only carries the unbalanced load so in this hypothetical situation the neutral at the panel carries 0A. So the answer to the question is...if you install ONLY 120v single pole breakers, you can run up to 200A on those circuits (or 80% of that as we have discussed.) But you are only running 100A on each leg of the service conductors and breaker.
What is average 208-230 voltage?
208V is one standard in the US for light commercial 3-phase power. It measures 208V phase to phase and 120V phase to neutral. 230 (or 240)V refers (in the US) to the common service supplied to residential. It is single-phase, with two hots and a neutral; 120-0-120. One hot and the neutral (120V) is used for receptacles and small appliances, both hots (240V) are used for large appliances, such as stoves, ovens, air conditioning, and water heater.
If you had 277-480 3phase power feed can you still use it to power IT equipment rated at 110-120V?
yes

Where can you find a 120V power cable?
You can find a 120V power cable at your local hardware store. Look in the section under extension cords.
Can I use 120v 10a 1250 w cable for projector 110-240v power in India?
You can use 120v 10a 125w cable projectors 110-240v power in India.
How many volts normal home 400 amp service?

What is the standard power of apc 1500?
The APC 1500 has a standard power of 865 watts/1500 VA. The APC 1500 has an output of 120V and an output of 120v. The specifics of the model can be found on the official website.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
What voltage does the power supply uses in US?
Input would be 120v at 60hz. Standard US wall power.
Do any Dehumidifiers run on batteries?
Due to the power required,you will need to runa dehumidifier using 120V power.
What will be the current flow of a 3 hp motor supplied with a 120 volt service?
1hp= 746Watts. So, now, we can take a simple power equation of P= IV, Solve for I, I=P/V, and plug in 746 x 3 for Power, and 120V for V.
What is the output on this exhaust fan?
This fan is rated at 277 CFM using 120V of power.
Where can you find a 120V electric power cable?
One can find a 120V electric power cable in stores such as Lowe's or Home Depot. It can also be purchased online through the store websites or through sites like rakuten for a cheaper price.
