120v and 240v cords usually have different end configurations and will not plug into the different recepticles. However, if you changed the plug end, and the cord has the proper size rating, then yes, you could use the same cord. But, it also depends on the cord too. Most 120v cords only have three wires in them. One "hot one "neutral" and one "ground" wire. A 240v cord would have FOUR wires, two "hot" wires, one neutral wire, and one ground wire. Therefore, if you changed the voltage from 120v to 240 using a 3 wire cord, you'd not have a ground wire and that could be VERY dangerous.

Note that occasionally a 240v device (e.g. some motors) will only need three wires (red,black,green, no neutral) and can be wired with a 120v cord if the cord is rated for 240v.

How can you plug 2000 watts 240v into a 120v 20 amp breaker with out replacing your breaker and all the plugs on the line?

You cannot safely plug a 2000 watt 240v appliance into a 120v 20 amp breaker without risking damage or fire hazard. To use the appliance, consider installing a step-up transformer to convert the voltage from 120v to 240v before plugging it in. This will ensure the appliance operates correctly without overloading the circuit.


Can you convert an existing 120V plug on an appliance to a 240V plug not speaking of a converter but actually changing the plug so there are no long term effects on the appliance?

If I understand your question, Can you run a 110 appliance off of a 220 volt outlet? You could by only using one leg of the 220. You may also consider changing the outlet. Put in a regular 110 outlet and capping off one leg of the 220 in the wall box. You still have a neutral and a ground to work with. I read this as the questioner doesn't want to modify the outlet. Check the voltage ratings on the device. Many electronic devices nowadays can havdle 120V or 240V as it is cheaper to manufacture one powersupply and sell it everywhere. If your device is rated for 240V, you can put a 240V plug on it. If it only says 120V, no dice. 240V will burn it up.


240V to a standard outlet?

You cannot plug a 240V appliance directly into a standard 120V outlet as it can cause damage or be a safety hazard. You would need a dedicated 240V outlet and possibly a step-down transformer to safely use the appliance. It's recommended to consult an electrician for proper installation.


Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?

No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V


Can you lose 240v but not 120v from main power line to house?

Yes, it is possible to lose 240V while still having 120V from the main power line to a house. This can occur if there is a fault or disconnection in one of the phases supplying the 240V circuit, which typically consists of two 120V lines. If one phase is lost, the 120V circuits connected to that phase will be affected, but the circuits on the other phase may still function normally. However, this situation can lead to unbalanced loads and potential issues with appliances.

Can a kitchen stove be on the small appliance circuit?

No, unless it's a gas range. An electric range requires 240V and 40A while a small appliance will be 120V and Max 15A.

Can you use UK appliances in the us?

Not unless the appliance is rated to be used with the two different power supplies. The US uses 120v, 60 Hz if it plugs into a receptacle, and possibly 240v, 60Hz if it is hard wired. The UK uses 240v, 50Hz whether it plugs in or is hard wired. These two power systems are NOT compatible. You may use a US appliance in the UK, and vice versa, only if the appliance is dual rated, i.e. the appliance says 120v/60Hz AND 240v/50Hz on the nameplate. If the appliance only specifies one power supply, it can only be used on that power supply. If this is the case, you may be able to use a travel adapter to operate the appliance.


How can you convert US 120V or 240V circuit into a single phase 240V circuit to use on a European appliance?

The voltage isn't a problem, you can run 220 from your house and use that to run a European appliance, the problem is whether the appliance is dependant on line HZ. European is 50HZ and US is 60HZ. If the appliance specifies 220/50HZ, it will probably give you trouble here. If it says 220V/50 or 60HZ


Can 240V washer run on 120V outlet?

No.


You are building a new house and trying to decide between 120v and 240v which is better More practical?

In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.


Why are you not getting 240v between the two hot wires?

Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
