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.

How many amps will a 250 kVA transformer in 220 volts secondary?
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
How many watt transformer is needed for 2.5 amp motor?
A 60-watt transformer would be sufficient for a 2.5 amp motor, as a general rule of thumb is to multiply the amps by the voltage to determine the power rating in watts. At standard household voltage (120 volts in North America), 2.5 amps x 120 volts = 300 watts. However, it's recommended to use a transformer with a slightly higher wattage to account for potential power surges or fluctuations.
What do you do to change the voltage of a 12 volt battery to a 6 volt output?
To change the voltage of a 12-volt battery to a 6-volt output, you can use a voltage regulator or a step-down transformer. A voltage regulator will reduce the voltage to the desired 6 volts, while a step-down transformer will step down the voltage from 12 volts to 6 volts. Both options will help you achieve a stable 6-volt output.
How many amps does a 12 volt 600 watt transformer use at 120 volts?
A transformer does not use, it transforms voltage from one value to another. The output amperage is governed by the connected load. If the load wattage is higher than the wattage rating of the transformer then either the primary or secondary fuse will blow or the transformer will burn up if the fusing is of the wrong sizing. The maximum primary amperage can be found by using the following equation, Amps = Watts/Volts, A = W/E = 600/120 = 5 amps. The same equation is used for the calculating the maximum secondary amperage, A = W/E = 600/12 = 50 amps.
How many amps does a 120 Volt irrigation controller draw?
Different controllers have different outputs depending on how many valves are on each zone. In the device there is a control transformer. Look for the VA output of the transformer's secondary side. Mine states 20 VA at 24 volts. To find the amperage use the following equation. I = W/V. Amps = Watts or VA/Volts. Mine can output 20 divided by 24 = .83 amps. This amperage will be the maximum output in amps that the controller can produce to operate the zone valves. To find the current draw of the primary side of the transformer divide the transformers VA by 120 volts.
How many volts from a transformer?

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.
How many volts does a mini connector have?
Depends on use,supply,AC,DC .Voltage,transformer ???
480 transformer to 120 ac current what is the kva on transfomer?
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
How many volts per hour does a 75 kva transformer produce?
Volts per hour is an invalid statement. You may have meant Watts per Hour.
How many amps will a 0.25 kilo volt amp transformer at 120 volts put out?
2.083 amps
How many amps will a 250 kVA transformer in 220 volts secondary?
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
How can find the primary turns of the transformer knowing the primary voltage of the transformer?
The ratio of the primary voltage to the secondary voltage is proportional to the ratio of windings. So if the primary voltage is 120 volts and the secondary is 240 volts there are twice as many turns in the secondary.AnswerAs the previous answer says, you can work out the turns ratio of a transformer, but knowing the primary and secondary voltages will not help you determine how many turns are on each winding.
1500 kva transformer equals how many amps at 480 volts?
480 volts is probably 3-phase (Line to line) voltage, so: 1500K / (480 x 1.732) = I = 1804Amps
7200 volt 25kw transformer how many amps at 240 single phase?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
How many volts is in a battery?
Batteries come with different voltages.
How many volts does a standard PC require?
PC manufacturers supply units in various countries for the domestic house voltage applying there. In the US this is 120v, in Europe 230v, and in Japan 100v. The PC internal volts are identical, they simply have the required transformer/rectifier to give this from the house supply, whatever its value. In some cases the PC can be supplied with dual voltage capability, to make use either side of the Atlantic possible.
