How do you convert a 125 volt to a 120 volt receptacle?

You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.


Why are you getting 123V at your dryer outlet?

You are probably measuring between the one leg of the 240 volts and the neutral or the ground pin connection. Take the measurement from the two outside blade holes on the receptacle. There the reading should be 230 to 240 volts. Between either of the outside blade holes and the neutral or ground you should read around 120 volts.


Is a 110 volt electric receptacle the same as 120 volt receptacle?

Yes, the rating on the receptacle is the maximum amount of voltage that is legally allowed to be applied to the device.


What would indicate a properly polarized and grounded outlet?

For North American wiring systems there is a test device known as a receptacle tester. It is a non-expensive device that just plugs into the wall receptacle. There are three lights that light telling you how the receptacle is configured. Newer devices also have a push button to test GCFI receptacles.In general, using a volt meter "hot" to ground equals 120 volts. Hot to neutral equals 120 volts. Neutral to ground no voltage. Large blade hole is the neutral and small blade hole is the "hot" connection, many times these will be reversed. If any of these examples are not met, then there is a wrong configuration of the wiring of the receptacle. Best answer is to buy a receptacle tester, even the electrical inspector carries one with them when inspecting new wiring jobs.


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.


Is a grounding 120 volt receptacle larger than an ordinary receptacle?

No, it just has an additional conductor to separate the neutral from the ground, and has a third prong in the receptacle to receive the appliance grounding conductor through the cordset.


What is the position of the ground pin on wall receptacle?

In North America on a 120/240 volt home electrical system, the ground pin on a duplex wall receptacle is on the bottom.


Can you plug in a 120v15a light lamp into a 120v20a receptacle?

YES, and the actual power is 117VAC not 120.


Can a hps light fixture be plugged in to a regular outlet?

If the ballast of the HPS fixture has a 120 volt tap then, yes it can be plugged into a 120 volt receptacle.


When measuring voltage across a receptacle you read 120 v across black and only 20 volts across white wire?

the white wire is your neutral side (ground usually), the small potential you're measuring is bleed current

How many volts come out of a average outlet?

Voltage does not come out of an average home outlet under normal circumstances.In North America the common potential voltage is 120 volts and is always at the receptacle as long as the circuit is energized. When an electrical device is plugged into the receptacle, through the device's connected cord, this brings the potential supply voltage to the electrical device.When the device is turned on a current (amperage) will flow, governed by the resistance of the device. If it is a lamp, it will become bright. If it is a radio you will hear sounds.When you unplug the electrical device from the receptacle, the device will stop operating but the voltage potential will still remain on the "hot" side of the receptacle's blade contact point.
