Answer for USA, Canada and countries running a 60 Hz supply service.

Use one leg of the 240v and the neutral wire. Most electric dryers run the motor this way. The heating element is 240v but the motor is 120v.

NO, THAT IS DANGEROUS ADVICE because a 240 volt service has a circuit breaker which is sized for the current draw of a large 240 volt appliance, so it would have a rated amperage that is too high to protect a 120 volt motor running on its own.

Only 240 volt appliances such as dryers, air conditioners, etc. are safe to use on 240 volt circuits.

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.

Can you use 120 vac 60 hz drill in a 240 vac 50 hz power outlet?

The voltage is OK, but certain types of motor can't be run on the wrong frequency. If the appliance uses a commutator motor, like many hand tools, it would probably be OK.


Are there tri-voltage motors?

On some motor nameplates you may see 120/208-240. These are not true tri-voltage motors. They are dual voltage motors with a leniency on the 240 volt range to be derated to run on 208 volts. At this voltage the current drops and you don't get the full horse power rating of the motor. To answer your question I have never seen one that would do true three voltages like 120/240/480.


What happens to your air conditioner if you lose one 110 volt phase?

If it is a 240 volt conditioner it will stop. If it is a 120 volt conditioner it will stop if it is on the leg that has been lost.


You have 380 volt electric motor 3 phas 7.5 kw you want to chang it to 240 volt can some one hepl pleas?

That's a powerful motor, and would need a supply greater than 13 amps at 240 volts, also the conversion might be difficult. I have a feeling that you would be better off finding out how powerful a motor you would need for the task you have, then buying a suitable 240 volt motor. You are heading into territory where you should really consult a qualified electrician.


How many 125 watt bulbs can be used on a 15amp circuit?

Assuming that your voltage is 120 volts the maximum wattage on that circuit is W = A x V = 15 x 120 = 1800 watts. Code only allows circuits to be loaded up to 80% capacity. 1800 x .8 = 1440. 1440/25 = 57 lamps. Assuming that your voltage is 240 volts the maximum wattage on that circuit is W = A x V = 15 x 240 = 3600 watts. If the question is from a 240 volt country you will have to find out what the local electrical regulations are for circuit loading.

Can you run a double phase motor on home 220 volt system?

If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.


How can I convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter?

To convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter, simply plug the adapter into the 240 volt outlet and then plug your 120 volt device into the adapter. The adapter will step down the voltage from 240 volts to 120 volts, allowing you to safely power your device. Make sure the adapter is rated for the appropriate wattage to avoid damaging your device.

Does a 6 amp 240 volt appliance hook up to 110?

No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.


Can a 240 volt sub panel run 115 volt motor?

In Europe 240 volts is standard, so no a 115 volt motor will not work. In USA 120 volts is standard, so if your sub-panel has 120 volts, (check with voltage meter) then yes. Read carefully, To get 240 volts in a sub-panel in USA the electric company brings two (2) wires, each wire has 120 volts, 120 + 120 = 240. One of those 120 volts will run your motor. Look for the wires from the electric company and check them with your voltage meter. If this is a commercial application you will need to call an electrical contractor, power companies for commercial applications do not follow the above.


Does 120 to 240 volt equal 20 amps?

no


Can you use 240 volts with a 120 volt supply?

No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.


What the difference between a 120 volt and a 240 volt waffle iron?

One has an element designed to work on 120 volts, the other has an element designed to work on 240 volts.


What are the differences between 120 volt and 240 volt electrical systems?

The main difference between 120 volt and 240 volt electrical systems is the amount of voltage they provide. A 120 volt system is commonly used for household appliances and lighting, while a 240 volt system is typically used for larger appliances like stoves and dryers. The higher voltage of a 240 volt system allows for more power to be delivered, making it suitable for heavier electrical loads.


What are the differences between 240 volt and 120 volt electrical systems and how do these differences impact the efficiency of household appliances?

The main difference between 240-volt and 120-volt electrical systems is the amount of voltage they provide. 240-volt systems deliver more power than 120-volt systems, allowing appliances to operate more efficiently. Household appliances that require higher power, like ovens and dryers, typically use 240-volt systems for better performance.


How do you connect a 240V electric cooktop with four wires to the 120V services from the electric panel which is 2 wires?

If your electrical service is only 120 volts you have a problem. There is no way that you can connect a 240 volt cook top to that service. You have two options, one is to upgrade to a new 120/240 volt electrical service. Your other option is to find a 120 volt electrical cook top.


Can a 110 volt motor run on 240 volts without damage?

No, unless the motor was wound for dual voltage operation, which it will state on the motor nameplate, a 110 volt motor run on 240 volts will be damaged.
