Can you wire a 120V stove fan to the 240V supply?
No, you must break it down to a 120 volt supply.
120 volt or 240 volt electric heat?
240V is much more effecient, and you can put more heaters on a 20 amp circuit than you can a 120V.
How do you rewire a 120V lamp to a 240V?
If your trying to plug in a 110 Volt lamp into 240 volt outlet the answer is simple. You must buy a step down transformer, or your lamp will burn out.
If you buy a light in the US with wiring for 120V can you take it to a 240v country and just change the plug?
If the light you refer to is just a plain incandescent lamp, then changing the plug and changing the lamp to a 240 volt lamp should work OK If the light has a ballast (transformer-like winding) of any kind, the voltage rating of the ballast has to match the line coming in. A few ballasts have multiple taps - you may be able to change the internal tap from 120v to 240v you can not convert it. Otherwise connecting a 120v ballast to 240v will damage it quickly.
120V light fixtures wall mounted you want to convert to 240V for a house overseas?
It will work it you use 240 volt light bulbs.
How can you tell if the electric service is 120V or 240V?
I think the only sure way is to put a high-impedance volt meter and measure the voltage across live and neutral. Don't forget that it's AC. You could look at the bulbs in the lighting to see if the say 120v or 240v.
Will a 250 volt cord work for 240 volt appliance?
wire in the us is available in 300v or 600v ratings so 300 volt is good for 120v 240v or 277V 277V is usually only used in lighting
How do you Wire a 240 watt meter for 120 volt?
240 watts to 120 volts? Or 240v to 120v? What kind of meter? As in an electrical test meter?
Can you convert a 240V circuit on your service panel to two 120V circuits?
A 240 volt breaker can be removed and replaced with 2 - 120 volt breakers. The existing 240 volt breaker should not be used to supply 2 separate circuits.
Can a 120v light bulb work in a 240v lamp?
If you mean that the lamp is rated for 240 volts then yes, a 120 volt bulb will operate in it if the lamp bases fit. If the 240 volt lamp is operating on 240 volts then no, a 120 volt lamp will not work in the fixture.
On a 220 volt circuit where the white wire is common how many volts would the red wire be?
ANSWER FOR THE US: The red wire should have the same as the black, which is 120V to ground, or 120V to neutral. Without the neutral, you will have 240V line to line.
How can you wire one half of a 20 amp 120 v duplex wall socket to run 240 volts over 2 legs 2 separate 120 v legs?
You can't. I'm not sure exactly what you're trying to do, but the way it is written is not possible. It seems you might want to use half of a duplex receptacle for 120 and half for 240. This would not be code compliant, nor would it make sense. A plug designed for 240v will not even fit into a 120v receptacle. You need a 240 volt receptacle rated for the amperage you will need. Also, an existing 120v receptacle has nothing to do with your 240v receptacle. For a 240 volt receptacle, you'll need to run 2 new 120v lines (in the same cable). The existing 120v circuit cannot be used here, even if you added another 120v circuit, because when a load uses 240v, both 120v circuits supplying the 240v must be controlled by a common disconnect (a 2 pole breaker designed for 240v circuit). My advice would be to show an electrician what you want done. I'm sure they can tell you how to make that happen.
