Only if the cable going to your well pump is a three wire. The third wire could carry the neutral and you will have 120 volts from either 240 leg to the neutral.

If your question is "Can 240 be produced from 120 volts"? This would require a step up transformer.

If by 240 volt box you mean a tap from a junction box then the answer is no. The 120 volt circuit would need its own breaker and wire, sized to correctly supply the 120 volt load.

How many volts does a house run on?

120 volts and 240 volts. Typically 240 volts is supplied to the house electrical service entrance. It is split into it's 120 volt components via two buss bars. Hooking a circuit up to just one bar yields 120 volts. Hooking into both gives 240 volts.


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.


If building is serviced with 480 volts and you put a meter between ground and hot what will be the reading?

For alternating current, and assuming the supply transformer is properly grounded, you will have 240 volts to ground. 480 volts; single phase will have Line1 and Line2, both with 240 to ground and 480 across both Lines : three phase will have Line1, Line2, and Line3, all will have 240 to ground, and 480 across any two Lines. Same is true for 240 volt service, 120 to ground and 240 across. 120 volt service is 240 volt service using ground as neutral.


How do you convert 120 volts electric fan to 240 volt?

put double power batteries in


Can you put a 120 v receptacle on a 240 v circuit breaker?

No, the electrical insulation rating of a 15 amp duplex receptacle is only rated at 130 volts. The 15 amp 240 volt receptacle is rated at 250 volts. The 240 volt receptacle also has a tandem pin configuration instead of the parallel configuration of the 120 volt device. The different pin configuration is so that a 120 volt electrical device can not be plugged into a 240 voltage receptacle.

How do you switch from 120 volt to 240 volt in house?

Answer for USA, Canada and countries running a 60 Hz supply service.To operate a 240 volt load in the home you use two adjacent breakers. This will give you a voltage of 240 volts where as one breaker to neutral will give you 120 volts.

Can a 10-2 wire be connected to a 10-3 recepticle for a dryer?

No, the dryer needs 120 volts supplied by the neutral third wire, along with the 240 volts for the dryer element. One of the two 240 volt supply conductors is used with the neutral to supply 120 volts to the controls and the drum motor. That is why a three wire cable is needed.


Can you use a 120 volt power bar with 240 volts power supply?

No, but check the specification on the power bar to see what its maximum voltage rating is. There will be a bit of cord end cutting to get the right configuration for 240 volt equipment.


Will a 240V 60hz cooktop Summit Appliance Three Burner CR3240 work in with 220V 50hz power?

The resistive elements will work. On 240 volt 60 Hz North American ranges there are clock and timer controls. These are operated on 120 volts. That is why these ranges are fed with a three wire cable. Two hots (240 volts) and a neutral (120 volts to either "hot" leg). A 220 volt 50 Hz power supply will not have a split winding to supply the range with its 120 volt source.


Can i run a 240 volt water heater on 120 volt?

No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
