If they are distribution neutrals you have the option of joining them together. Without more information it is not possible to give an answer to this question.
If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.
white wires are neutral. green wires are ground wires.
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
Yes, you can connect the light fixture wires to the house wires by matching the colors appropriately. The black wire from the fixture should connect to the red wire from the house, as both typically serve as "hot" wires. The white wire from the fixture should connect to the white wire from the house, which is the neutral. Finally, connect the ground wires (bare or green) together to ensure proper grounding.
On a three wire supply system if you connect the two 110V wires together and they are across the phase they will short out and trip the breaker. If the two 110V wires are supplied from across the phase and connected to a motor then the motor will run. If the 110V wires are on the same phase nothing will happen.
It sounds like you are talking about a two tube eight foot fluorescent fixture. Open the fixture up and you will find a ballast that has probably two yellow wires, two blue wires, two red wires and a black and white wire coming out of it. The 120 volt supply will connect to the black and white wires that protrude out of the ballast. Black ballast to black supply and white ballast to white supply.
If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.
white wires are neutral. green wires are ground wires.
a usb cable has four wires, two for power and two for communication.
The White Wires was created in 2007.
If you are not sure what wires where were it is best to call an electrician. In the US, the black is power, white neutral, and green ground.
Connect to two wires you have to the the spade connectors and forget the ground connector. The spade connector wires should be black and white. Black to gold and white to silver. If the wires coming from the heater happen to be red and white, then red goes to black. You could buy a simple lamp cord which has only tow wires.
If there are two black wires, it's possible that it was wired for a ceiling fan and that one of the wires is for the fan part while the other is for the light part. If so, one of the black wires may be switched while the other is always "on." Normally black is "hot" and white is "neutral" (NOT ground... ground is usually green).
If the wires are incorrectly connected the idea is that it will blow the fuse.
repel each other
The wires are twisted pairs and have to be placed in a certain way for the cable to work. The industry has a standard that all cables and glands are manufactured to. Alternating the white wires was probably done for clarification as to which pair of wires went to what termination so as not so get the white wires from the pairs mixed up.See related links below.
Wiring to the circuit breakers is 220 volts. The circuit breaker box has 2 110 Volt lines. If you connect two black lines together from one side nothing happens. If the these two black wires are from different circuit breakers you may have a safety issue by back feeding the electricity. If you connect 2 different 110 volt lines you will end up with a short. This ends up as a 220 volt short.
