To get 240 VAC from 120 VAC, you need a step-up transformer. <><><> The first answer shown above is not recommended at all unless you only want to supply 240 volts to a very small piece of equipment such as a radio, music center or similar. It would not be possible to use a transformer to suppy 240 volts to a large appliance such as, say, a clothes dryer taking, say, 30 amps, because a) the current drawn at 120 volts would be over 60 amps - and that would certainly cause the circuit breaker to trip on a standard 15 amp or 20 amp 120 volt branch circuit - and b) the cost in dollars of such a transformer would be enormous and it would be very heavy too! As you asked this question, if you want 240 volts for a large appliance such as a clothes dryer, range or water heater, the best advice anyone should give you is to have a new branch circuit installed professionally by a licensed electrician. It would have: * the correct size of circuit breaker; * the correct size of cable for the distance from the main breaker panel; * the correct type of grounding protection for the location where the appliance is to be used; * the correct size of outlet onto which the appliance can be connected safely. See the answer to the Related questions shown below for more information. <><><> If you mean "How do we get 240 VAC in a US home where there is 120 VAC?", understand that our power is actually 120/240 split phase. We run one phase to half the 120 VAC loads, and we run the other phase to the other half of the 120 VAC loads. Those loads that require 240 VAC get both phases. Note: This is not two phases of three phase power.<><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

Why neutral is required?
Neutral is the current return for the hot leg(s). Neutral is grounded, so as to limit the maximum voltage of any of the hots with respect to earth ground. In a typical residential 120/240VAC split phase system, either of the hots with respect to neutral is 120VAC. In a three phase system, neutral is at the center of the wye configuration, and each of the three hots returns power to it.
How do you wire a 30A 240VAC disconnect?
To wire a 30A 240VAC disconnect, connect the black and red wires to the line terminals, the white wire to the neutral terminal, and the green or bare wire to the ground terminal. Make sure to follow the manufacturer's instructions and local electrical codes to ensure proper installation and safety. It is recommended to consult with a licensed electrician for assistance if needed.
What happens when current travels through the second transformer before entering your home?
When current travels through the second transformer before entering your home, it undergoes a further step of voltage reduction and may be adjusted for the specific requirements of the local distribution network. This helps ensure a safe and consistent supply of electricity to your home at the appropriate voltage levels for your appliances and devices.
How do you convert 1500 watt 240Vac to 375 watt at 12Vac?
To convert power from 1500 watts at 240V to 375 watts at 12V, you can use the formula P=VI (power = voltage * current). First, calculate the current at 240V by rearranging the formula to I=P/V. Then, input the current calculated at 240V into the formula to solve for the current at 12V. Finally, rearrange the formula P=VI to solve for the power at 12V using the current calculated in the previous step.
White wire a black wire a red wire and a bare wire?
The white wire is typically neutral, the black wire is usually hot or live, the red wire may be a secondary live wire or used for a separate function, and the bare wire is typically the ground wire for safety purposes in an electrical circuit.
What is the voltage rating for 240VAC?
240 volts alternating current (240vac)
How can i make a winding of a transformer of an inverter of 12vDC to 240vAc?
850va 12vdc inverter transformer praemari tans
what is the power source to assemble a toaster?
AC supply of 220V for domestic use. So appliances normally have the range of 220Vac - 240Vac.
What is the cost difference to operate a 240 VAC motor versus 120 VAC motor.?
Sadly, there's no simple answer to this question. The only advantage of 120VAC that it's the standard in the US and Canada, so it's easy to find outlets, extension cords, and plugs, as long as you need less than 15 amps (about 2 horsepower). The same current flowing at 240VAC delivers twice the power that it would at 120VAC; so for equivalent power, 240VAC requires half the amperage. This lets you use smaller cheaper wires, and for a given wire size reduces the resistive heating in the wire. For these reasons, electricity-hungry appliances like electric water heaters, electric ovens, and big power tools are usually 240VAC. Surprisingly, other than perhaps a few percent reduction in resistive heating, you won't save any money on your electrical utility bill by switching to 240VAC. This is because you get charged by power used, not current used. When considering a new power tool, the downside of 240VAC is you often need a special branch line and outlet, which normally needs to be installed by an electrician, and may even require an upgrade to the house's electrical service. And your equipment will need special plugs, since there is no single standard 240VAC plug. The upside is lower resistive heating in the cord, and the ability to deliver up to tens of horsepower.
What is the role of a transformer in a neighbourhood?
High voltage(23000vac) is delivered to your community then stepped down(240vac 2 phase 120v to neutral) to allow use of common household appliances.
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
What does 100 - 240vac to 12vdc mean?
"100 - 240VAC to 12VDC" refers to a power supply unit that can accept an alternating current (AC) input voltage ranging from 100 to 240 volts and convert it to a direct current (DC) output voltage of 12 volts. This type of power supply is commonly used in various electronic devices, allowing them to operate efficiently across different regional voltage standards. The versatility in input voltage makes it suitable for use worldwide.
How much voltage is required to run a 5 gallon compressor?
A small unit like that will most likely be 120vac. If you check the motor it may be 120/ 240vac, meaning that by changing wiring in motor, you have a choice of voltages. lc
Do you plug into 120 or 240 on your generator for home use?
In the U.S. the normal voltage for appliances (refrigerators, washing machines, lamps, microwaves, computers, televisions, etc.) is 120vac. Such things as air conditioners, electric ranges, electric clothes dryers, etc. use 240vac.
