Is it normal to read 120v on black and white AND black and ground?

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.

Which wires go where when putting a power cord on a 120V compressor motor?
In common house wiring, black is the power wire, white is the neutral, and green is the ground wire.
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
Which color wire is normally not on a 120v system in an apartment?
Black
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 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.
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 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.
How many volts normal home 400 amp service?
120v /240v
How do you wire a 1500W 240V flood light that has ground white and black wires?
the wires coming off double pole will give you 240 volts,110 each the black and white hook to these,doesn`t matter which way,ground to ground Ground is always ground, Black and white are your two "hots." You will need a dedicated circuit, you cannot run this off existing 120V wiring. A 15A 240V circuit should be more than sufficient. If this is a permanent instalation you can use 14/2 wire as you normally would, and wire it as you normally would with the exception of the 240V breaker. If you install switches, timers, etc. Make sure they are all rated for 240V. Remember, you can't just mix-and-match between 120 and 240V. 240 appliances will not run on 120 and 120 appliances will burn up on 240.
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?
In a typical electrical outlet, the bare wire is the ground wire while the white wire is the neutral wire. The ground wire is responsible for providing a safe path for electrical currents in the event of a fault or short circuit. In your specific case, it is possible that the bare wire is acting as a neutral wire, but it is crucial to consult a certified electrician for an accurate assessment and to ensure proper wiring connections.
