Yes. The white wire (the "neutral") is the "return" for the hot. Recall that electric current had to "get to where it is used" and then has to "get back" to the outlet. (A complete circuit is necessary.) You need the black wire (the "hot" wire) to carry the current out and the white wire to carry the current back, and the currents should be equal. You don't want any current returning on the ground wire or "leaking to ground" from anywhere in the circuit. Another way to look at this is that the black and white wires form "rails" for the voltage. Anything hooked up is connected "across" the rails. It's connected from the black to the white - from one rail to the other. All the appliances in the house are connected in parallel across the black and white, or in parallel across those voltage rails. (That's why all appliances operate on the same voltage and why if one fails, it doesn't affect any of the others.)

∙ 14y agoNo it is not a standard practice. That said you will find such a connection from a light fixture junction box, that has the supply source in it, down to a a light switch junction box. The neutral for the light is already at the light junction box but the switched leg has to go down to the switch. The black "hot" wire is connected to the white wire in the cable going to the switch and from the switch it returns in the black wire in the same cable which is then connected to the light fixture.

The black wire is hot but there is no current between the hot and neutral wire. There is current between the hot and ground wire?
You have a potentially deadly wiring problem in which the open neutral could mean someone accidentally switched off the white wire instead of the black wire, or some other horrible mistake. Please call a qualified electrician to diagnose this problem immediately.
Is it legal to buy a house with a 60 amp service?
Wow, never heard of it. Usually 100amp, usually it does not matter what the house has, because it is grandfathered in. But if you ever want to add anything to the service, you might be forced by codes to install a new 100 or 150 amp service, or you might not be allowed to do anything. Call the local power company and ask them if they will upgrade the service to the house for free. Some will. You will need an electrician to put in a new service panel. Could cost a thousand bucks or more depending on the current wiring. A home inspection would also be recommended before buying such an older house.
What are the three basic parts of circuts?
For a circuit, you usually need: * Conducting wires, or some other conductor to carry the current * A current source, for example a battery * A load (something that uses the power) * A switch that lets you disconnect the current flow
Who invented current thomas alwa Edison Michael Faraday Nikola Tesla thales or if some other person please name them?
Nikola Tesla patented alternate current which is used worldwide to light house ad buildings. Edison began selling electricity with the direct current but lost all the grandeur.
What are some examples of back dwarfs?
There are currently no black dwarfs. The time it would take for a white dwarf to cool to a black dwarf is greater than the current age of the universe.
What is the number of Democrats in the White House?
Some of the White House permanent staff may be Democrats, if they haven't been run off by the Bush administration, but the current administration is all Republican.
Is the house parallel or series?
House wiring is almost always parallel. Series wiring may be used for some switch circuits, however.
What are some websites focusing on current issues in education?
Some websites focusing on current issues in education are the Economist, BBC News and the White House. There are also education-based websites which also focus on issues in education.
If you change your panel do you have to rewire the whole house?
Not necessarily. It would depend on the condition of the wiring. If it is an older house with cloth covered wires it may be advisable to rewire. If existing wiring is aluminum you might also consider rewiring. Depending on the length of wires that enter the current box, you may need some external junction boxes.
