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

Back at the Electrical Panel. There should be a 220 breaker for that line to power what ever. Remove the 220 breaker switch (make sure the main power switch at the top of the box is off) and replace with two 120 breakers which are actually called 15 amp and 30amp

When you use the term "step it down" that is electrical terminology when talking about Transformers. If that is what you mean any 2:1 ratio transformer can be used as long as it is sized for the load on the secondary side of the transformer. 120 volts x amperage needed = Watts (VA).

If you are talking about electrical panel distribution breaker change from 240 to 120 then read the following.

Do this electrical work only if you feel confident that you can do it safely. If not then this is the procedure that an electrician would use and you would be able to follow what he is doing.

Again an electrician should be your first choice. If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU.

Before an explanation of how to do this you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 120 volts.

The existing two pole breaker in the distribution panel that is to be replaced should not have a larger rating than a 15 or 20 amps. The wire size from that breaker will be #14 or #12 respectively. The final results of this project will leave you with a 15 amp 120 volt receptacle and one spare 15 amp breaker in the distribution panel.

That said OK, any 240 volt outlet can be changed to 120 volt by removing the white wire from the 2 pole breaker and inserting it into the neutral bus bar. Remove the other wire (probably black) from the breaker.

Remove the 2 pole breaker from the breaker panel.

Install two single pole 15 amp breakers into the hole left by the 2 pole breaker. Leave both of these breakers turned off.

Connect the black wire that came off of the 2 pole breaker on to one of the new single pole 15 amp breaker.

Re install the cover to the electrical panel, this end is finished.

At the old 240 volt receptacle, remove the existing device and install a new 120 volt receptacle.

Materials can be purchased at local building supply store. Remember to take the electrical panel data with you so you have the information for the 2 new breakers.

Once you have the new 120 volt receptacle installed, identify on the electrical panel door what the breaker is used for.

Leave the unused breaker in the off position.

Turn the new 15 amp breaker on.

Turn the main breaker back on.

Test the new receptacle with a lamp to make sure every thing is OK.

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.

How do you convert your 110 volt neon sign to run off 240 volt UK socket?

What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.


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.


Can a 12 volt light be run on a 120 vac timer switch?

No and yes. A 120-volt plug-in timer connects the line voltage to the timer and to the switch that is operated by the timer, so you can't use it directly for a 12-volt light.However, if you use the timer to supply power to a step-down transformer, you can run a 12-volt light off the transformer (that's how most low-voltage landscape lighting timers work). If you don't need much current, you could even plug a 12-volt AC adapter "wall wart" into the timer. Otherwise, you would have to open the timer and modify it so that the micro switch is completely isolated from the 120-volt supply and bring it out to connectors for a 12-volt supply. Make sure you know what you're doing and also don't exceed the current capacity of the switch.


How do you know whether to get 120 volt or 130 volt light bulb?

Choose a bulb with the same voltage as your fixture to prevent damage or risk of overheating. If the fixture specifies 120 volts, use a 120-volt bulb. If in doubt, consult the manufacturer's instructions or a professional electrician.


How do you convert 277v to 120v for an outlet?

i think you just have to change the breaker from a 277 to a 120. 277 breakers are usually a 2 pole breaker and 120 is a single pole breaker. NO. 277v is not two poles, it is one pole, one single pole breaker in a 480 volt 3 phase system (typically). If you want 120 volts from a 277 volt source you need a step down transformer 277 volt to 120 volt , or 480/277 to 120/208 .

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.


How do you convert your 110 volt neon sign to run off 240 volt UK socket?

What you will need is a 240 to 120 step down transformer. An adapter might work but it depends on what the current draw of the neon sign is at 120 volts.


Is there adapters for 250 volt to 120 volts?

No. There are no "adaptors". To get 240V from a 120v supply you use a 120-240V step up transformer. &lt;&gt;&lt;&gt;&lt;&gt; Clothes dryers, water heaters and and other high-power 240 volt appliances cannot be run on a transformer from a 120 volt circuit. They must be powered from a separate branch circuit that has the right size breakers, cable and socket outlet to suit the appliance.


Will a switching power supply work on 277 volts?

Not unless it is rated for that voltage. You can likely find a step down transformer from 277 volt sto 120 volts.


Where might a step-down transformer be used?

Step-down transformer is used at grid substations for feeding various substations which further step down the voltage for feeding distributing transformers and further step down transformers are used to supply the voltage for the consumer uses


How can you rewire your 220 volt motor to run on 120 volts?

If a motor is designed to run on different voltages there will be a wiring diagram on motor plate for 120 volt wiring. If not you will have to use a step up transformer to convert 120 V to the higher voltage.

Can you get 110 volts from 277volts?

The voltage of 277 is the wye connection of a 480 volt three phase supply. The only way to reduce 277 to 120 volts is with a step down transformer.


How is coil a transfer of energy?

Coil is a transfer of energy because it takes energy to make coil burn which is reduced as heat/ light energyMy VersionA electrical coil will step up (convert) voltage and electrical energy or step down depending on how it is designed. EG: A coil called a transformer will take the 600 volt power from the power grid and turn it into 120 volt power in your house.


How do you convert 230 volts to 12 volt system?

With a Step Down transformer. But you will probably have a hard time finding a 240 volt unit. 120 volts units are readily available. &lt;&lt;&gt;&gt; It depends on how big of a transformer that you are looking for. There are many control transformers in the 50 to 500 VA range that have dual primary and dual secondary. The primary side can be connected to 240 volt or 120 volt and the secondary can be connected for either 12 or 24 volts.
