No. You need to rewire the circuit from the electric panel.
You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.
No. To prevent this sort of thing from happening, the 277 volt device and receptacle is physically larger that a 240 volt receptacle and will not fit in a regular receptacle junction box. For a 277 volt system the proper size junction boxes have to be purchased.
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.
That appliance might last longer if you use an eight volt adapter rather than a nine volt adapter.
An adapter can be used. Make sure that the adapter that you use is of a capacity that it can produce the amperage that your appliance needs. An adapter too small will burn itself open and will be of no use to anyone. Remember; Watts = Amps x Volts.
No
Not directly. Maybe with a proper adapter. Even if the TV plug fits into the receptacle (it shouldn't), the TV would not work and could possibly overheat or cause a fire, or be damaged internally.
Yes, we have a 230-volt plug adapter available for purchase.
The maximum current rating for a 20 amp 250 volt receptacle is 20 amps.
No. an AC adapter will not work for equipment that needs DC.
No, of course not. The 6v adapter only produces 6v, while the load expects 9v.
It sounds like the same thing to me.
