It is normal to measure 120 volts from black (hot) to white (neutral), and it is normal to also measure 120 volts from black (hot) to bare (ground). While the hot wire stands alone, the neutral and ground wires are tied together at the service entrance -- so either one can serve as reference for making a measurement to the hot wire.
What else can I help you with?
Which is the ground wire and which carries 120V on an old 240V welder that needs a new plug at the end of the power cord if the wire colors under the outer insulation are white green and black?
If you only have 3 wires you don't have the fourth wire for 120V. Since this is a 240V only device it doesn't need it. Black and white are your hots and green is ground.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How can you plug in 120V appliances such as a TV and VCR to an old 240V air-conditioning outlet with one white one black and one grounding?
At the breaker box the black and white will be on a double-pole breaker (or maybe even two separate breakers). To convert to 110V attach the black to a single pole 15 amp breaker, the white to the neutral bus bar (like all the other whites in there) and the ground to the grounding bar (like the other grounds). Then replace the receptacle with a regular 15amp 110V.
Which color wire is normally not on a 120v system in an apartment?
Black
Which wires go where when putting a power cord on a 120V compressor motor?
Connect the green wire to the ground terminal, the white wire to the neutral terminal, and the black wire to the hot terminal on the compressor motor. Make sure to follow the manufacturer's instructions and safety guidelines when wiring the power cord to the motor. If in doubt, seek the assistance of a qualified electrician.
On a 220 volt circuit where the white wire is common how many volts would the red wire be?
3 OR 4 . you only need 2 wires for 220, 1 phase is 120v between 2 of them its 220v . you also should have a ground for the third wire ,and the newer stuff requires a neutral or white wire for the 4th wire. hope i helped , D
How do you hook the 4 wires which are 2 whites 1 red and 1 black coming from the back of a generator to an outlet for 120v and 240v?
The whites are Neutrals or Grounds and the Red and Black are each 120v. One white and either the black or red for 120v and one white, both the red and black for 240v.

What color should the wires be in a 120v system?
It depends. In a typical US residence with 120/240v single-phase power, the ground wire will be green, the neutral will be white, and the hot conductor will be either black or red depending on which phase it is connected to. Odd numbered breakers (1,3,5, etc.) are black, and even numbered breakers are red. You will measure 120v from black to white, also 120v from red to white, but 240v from black to red. In a commercial building with 3-phase 120/208 power, ground and neutral are the same color, but there are 3 hot colors - black (a-phase) red (b-phase) and blue (c-phase). As you run down a line of breakers from top to bottom they will be wired: black red blue black red blue etc. You will measure 120v from any of the 3 hot colors to white (neutral) but 208v from black to red, red to blue and blue to black.

What is 2 wire plus ground 240V?
With one interpretation of this question, the answer would be two 120V wires and a ground.

How do you wire a 120v A base emter for 120v?
To wire a 120V A base emitter for 120V, you would typically connect the emitter to the ground, the base to the input voltage source (120V), and the collector to the load. Ensure you follow proper safety precautions and consult the specific datasheet for the A base emitter you are using for correct wiring instructions.
How do you hook up a 3 wire water herter to 4 wire circut?
4 wire household wiring is black, red, (hot wires) white (neutral) and bare or green (ground wire). You say 3 wires. Is it 120v or 240v. If its 240v which is more common just use the two hots and the ground and cap off the neutral wire.
The 10-30 receptacle for the dryer has 3 wires white black and bare The volage across bare-white bare-black is 120v Is there any way the bare is neutral or is it ground?
The bare is ground. A bare conductor can only be used as a ground. The dryer doesn't need a neutral, its power flows from one hot (black) to the other (white). A load using only one hot needs a neutral to return to the panel. To make things easier to understand, when using 2 conductor w/ground romex for this (which already contains only black, white, and bare wires), I would color the white wire red with electrical tape on both ends. This way it won't be confused with a neutral.
In hooking up a 240V Air Conditioner you have four wires but only three on outlet What three go on receptacle Red Black White Copper?
For a 240V with ground outlet you will connect black (hot) to one brass screw, red (hot) to the other brass screw, and bare (ground) to the green screw. Cap white (neutral) with a wire nut. It is for 240/120V appliances. If you don't fully understand this buy a book. This is a very basic question. If you don't understand which wire is which you could make a serious mistake causing fire or death.
