How many volts come into your house?
For the USA its 240V (120V on each line/phase).
Does your house have 440 volt line?
No houses are wired for 440 volts. In the USA, most houses are wired for 240/120 volts called single or split phase. That means each "leg" of the service is 120 volts to ground, but across the two it sums to 240 volts, since each "leg" is 180 degrees out of phase with respect to each other. When one "leg" of the service is at +120 volts, the other "leg" is its mirror image, at -120 volts. In this way, connecting across the two yields twice the voltage of either leg to ground, allowing the use of 240 volt or 120 volt appliances depending on how connected- to ground or across "legs". Most other countries with 220-240 volt appliances do not use split phase service. There is only the one phase to ground and in those countries the incoming line is 220-240 volts to ground, voltage depending on the country.
IF YOU HAVE A 277 volt circuit IN you go from PHASE 1 to ground what will your voltage be?
In a 277-volt circuit, if you measure the voltage from Phase 1 to ground, you should read approximately 277 volts. This is because 277 volts is typically the line-to-ground voltage in a three-phase system where the phase voltage is 480 volts. Therefore, when measuring from the phase conductor to ground, the voltage remains the same at 277 volts.
How many volts come out of the transformer to go to the house?
There are 240 volts for a single phase service. <<>> A single phase transformer that feeds homes has three bushings. The two outside bushings are the working voltage (house connections 240 volts). The middle bushing is a center tap of the secondary coil. This gives a voltage of (bushing left to center 120 volts) and (bushing center to bushing right 120 volts) The center tap of this transformer is grounded and connected to the single grounded eight foot lower conductor if it is a pole transformer. The single phase service neutral is established at this point. These three secondary points are connected by triplex to the homes weather head where another connection is made to the homes service distribution. This is classed as a 120/240 volt service.
In North America what is the normal voltage for a house?
Residential applications are around 110v to 120v, 220-240v, in this range, its 120 volts nominal to a typical wall outlet, however you may read anywhere from 110volts to 120 volts or so, the highest I have seen personally in residential was 245volts.
Is your house 120 or 240?
It is usually 240. Two lines enter your house, carrying 120 volts each, but they are out of phase by 180 degrees, so the two combined entering your house provide 240 volts, which is necessary for powering central air conditioning systems. You also have the option of powering everything else in your house with 120 volts because of the phase difference of 180 degrees without the need of a 2:1 turns ratio transformer in your house. You breaker box in you basement is wired to take advantage of this phase difference, supplying the 240 and 120 volt sources to the places that they are needed. This is a huge advantage of AC power.
How many amp 25 tons packadge unit?
180 at 480 Volts 3 Phase
How many amps do you need to supply a 150kva transformer to get 118amps 480 volts?
Rephrase your question, as it doesn't make any sense. If the primary side of the transformer is 480 volts 3 phase, this transformer can be supplied from a breaker as big as 180 amps. If 480 volts 3 phase is your secondary then you can supply up to 180 amps to your loads.
What is the minimum voltage of US household mains supply?
240, single phase for houses208 3 phase for comerical property, can be single phase.480 volt for industrial property or 660 volts,all 60 HzUSA calls it single phase but there is actually 2 hot leads coming into the house with a natural and a ground.It is actually two 120 volt 'hots' which are 180° out of phase from each other. Voltage between either of these and ground will be 120 V. Voltage between the two hots is 240 volts. It is single phase because it is pulled off one of the phases from 3-phase, then a center tapped transformer gives the two 'opposite phases' (ground/neutral is off the center tap)In Vietnam we have 440 volts, 3 phase, 50 Hz on the poles.They bring in one hot wire and one ground. I call this single phase,It equals 220 volts in your house.
Is 126 volts three phase?
126 volts sounds very close to a standard home voltage of 120 volts, which is single phase. 208v is a three phase voltage, and is the lowest I have seen. 240 is single phase (usually center tapped, so in your house you have +120, and -120 referenced to the neutral which provides the normal 240 for dryers, stoves, etc.).
How many volts come into your house?
For the USA its 240V (120V on each line/phase).
Is it safe to connect 380 volts 3 phase supply to 220 volts 3 phase supply?
No.
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 phase constant in the equation when the values are 180, 0, and 180?
The phase constant in the equation is 180 degrees.
Does your house have 440 volt line?
No houses are wired for 440 volts. In the USA, most houses are wired for 240/120 volts called single or split phase. That means each "leg" of the service is 120 volts to ground, but across the two it sums to 240 volts, since each "leg" is 180 degrees out of phase with respect to each other. When one "leg" of the service is at +120 volts, the other "leg" is its mirror image, at -120 volts. In this way, connecting across the two yields twice the voltage of either leg to ground, allowing the use of 240 volt or 120 volt appliances depending on how connected- to ground or across "legs". Most other countries with 220-240 volt appliances do not use split phase service. There is only the one phase to ground and in those countries the incoming line is 220-240 volts to ground, voltage depending on the country.
What is single phase 480?
The utility company can provide a 480 volt, single phase service from a single phase transformer, usually with a three wire service. 480 volts is measured between the two line conductors, and 240 volts is measured between either line conductor and the common neutral conductor. The voltage of the line conductors are at 180 degrees with respect to the neutral conductor.
What is normal house current three wire single double or three phase?
Normal house current is two-phase, 240V. What comes into the house is two hots and a neutral. From hot to hot you get 240V and from either hot to neutral is 120V. In the electrical trade there are only single phase and three phase systems. The reason it is called single phase is that the primary connection on the high voltage side is one leg of a three phase system. This 3 PH system is usually about 12500 volts. On the primary side of the transformer, the connection is between one phase of the three phase system and ground usually in the area of 12,500/1.73 = 7225 volts. The secondary side of this transformer is 240 volts with a grounded center tap. As stated above this is where the 240, 120 voltages come from.
