What is the voltage for a single phase from a 415 volt 3 phase and neutral supply?
240V. 415 / 1.73 = 240
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?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
When the label says requires 208-240V 20amps 60HZ how do you know if it is single or three phase?
Please be more specific is this a transformer or motor or something else? Did you check the spec sheet? Did you look for any markings on the package?
Will a 240v 3 phase welder run better than 240v 1 phase?
Yes, because you will be able to maintain current flow between phases.
What is ac supply in America?
The most common voltage supply to homes is single phase 120V / 240V. In the states for industries, 3 phase 480 Wye 277. In Canadian industries, 3 phase 600 Wye 347 volts.
What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
What is the voltage and current for a single phase supply?
240v
Can you replace a 480-240V 3-phase motor with a single phase motor as a temporary replacement or will it burn it out?
Yes, you can, and it won't burn out IF>>> the horsepower rating is the SAME. Pay attention to wiring and motor rotation. Also check the voltage: the motor voltage must be the same as the voltage between two hots of your 3 phase system. You will only use two hots as this is a single phase motor.
What will happen if two phase supply given to the single phase motor?
Two phase is single phase for today's purposes. We generally do not call 240v single phase "two phase" anymore, although technically that's what it is. 240v two phase has power to both lines to the motor versus 120v single phase has one power line and a neutral. Fortunately most single phase motors today are dual voltage. So check your nameplate data of the motor for guidance. The use of proper motor protection will prevent any damage to motors if wrong voltages are inadvertantly applied.CommentA two-phase system is an archic system, in which two phase voltages are displaced from each other by 90 electrical degrees. Like three-phase, it had the advantage of producing a naturally-rotating magnetic field, so could drive induction motors without any need for a starting capacitor.
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.
How much more efficient is a 2 hp 240 v 3 phase motor compared to a 120 v single phase 2 hp motor?
A 240V 3-phase motor is generally more efficient compared to a 120V single-phase motor of the same horsepower rating because it provides smoother and more consistent power delivery. The 3-phase motor also tends to have lower operating temperatures and reduced energy losses, resulting in higher efficiency and better performance overall.
What is the voltage for a single phase from a 415 volt 3 phase and neutral supply?
240V. 415 / 1.73 = 240
If a 240v circuit hsa 30 amps per phase what is the amperage 30 or 60?
Still 30 amps, but at 240 V you'll have twice the watts that you would on a 120 V, 30 amp circuit, and after all, watts are what actually does the work.
Why ground the neutral of a 3 phase ac motor?
In a three phase motor each leg (3 phases) in the down cycle alternating at 1/60 per second servers as a neutral, you are only required to ground (green) the frame of the motor for safety. This is similar In a single phase motor wired for 240v (2 phases) the same thing happens and you are only required to ground (green) the frame of the motor for safety. From: Ken F
What is a Single pole electric service?
Do you mean Single Phase? This is what supplies American homes and some commercial buildings. It is 120V/240V.

If the loads were only 240v on a single phase 240v system with a center tapped transformer the neutral conductor would carry?
If the loads are balanced, the neutral conductor in a single-phase 240V system with a center-tapped transformer would carry no current, as the currents flowing in opposite directions would cancel each other out. If the loads are unbalanced, the neutral conductor would carry the difference in currents between the two lines.
