You disconnected a 240 volt wall heater now connecting the wire to a receptacle Is white wire hot in that case?

The white wire in a 240 circuit may be hot depending on exactly how it was wired. There are 2 120V circuits in a 240 v circuit and if all the electrician had was a cable with black and white then he very well may have used white as the other hot wire leaving 2 hot wires and no neutral. If a separate neutral was not run for the 240 circuit then a new cable may have to be pulled from the breaker panel that has a neutral. If you have the skills with a meter, you can check. If you are going to do this work yourself make sure that you shut off the main disconnect to the electrical panel and just use a flashlight to see the work you have to do. That said, it is common practice to use a two wire to feed wall heaters. You will find that the two wires are fed from a 2 pole breaker. Keep in mind that there should not be any other heaters on the circuit, if there is the other heaters will not work. In the electrical panel the white wire has to be taken off the 2 pole breaker and terminated onto the neutral buss. The other wire on the 2 pole breaker should be taken off and put into a single pole 15 amp breaker. Now on the receptacle end white wire to the silver coloured screw and black coloured wire to the brass screw.

What are the common wiring in a receptacle?
Black wire is HOT, white wire is NEUTRAL and bare or green wire is GROUND. The black wire goes to brass colored screw, the white wire goes to silver colored screw and the bare wire goes to green screw that is connected to the metal "frame" of the receptacle.
How do you rewire a 220 volt receptacle to produce 110 volts?
A 220 volt receptacle is a receptacle which has 2 wires carrying 110 volts...it has two "hot" wires at 110 and a neutral or common leg which has no voltage. A 110 volt receptacle is a receptacle which has 1 wire which carries 110 volts and a common wire. The wiring in the USA is almost standardized now to where the two "hot" (carrying 110 volts) wires are colored black and red, and the common or neutral is white. To change a receptacle to 110 volts..you remove the red or black wire from the old receptacle and wire nut it off...leaving the other red or black to attach to the new receptacle (right side of receptacle usually, looking at it from the grounding hole on the receptacle ON THE BOTTOM). You then connect the white wire to the left side of the receptacle. This will provide only 110 volts now. If the wires are not black, red, and white..they may be black, black, and white. In most cases, the white wire is always the neutral or common wire. When in doubt, buy a voltmeter and check each wire to the metal box in the wall...the wires carrying the 110 volts will usually read 110 on the voltmeter (or 115, 118..etc). Good luck!

How do you connect a 240 volt electric heater It is a baseboard unit the has a black and red internal wire for connection Do you use 12 2 wire or 12 3 wire The thermostat has 2 red 2 black wire?
2 wire (plus ground) is all you need for a 240 volt heater provided there is no 120 volt accessories in the heater such as a built in convenience receptacle. If cable is used, the white wire of the 2 wire cable will be a HOT-LEG even though it is white-this is one of the code exceptions. The size of the guage is dependent on the size of the load and other factors. 12 guage will handle up to 1500 watts generally.
Where do I put the red black white and copper wires on a 50 amp three prong recepticle?
The 50 amp receptical will not be a three prong receptacle it will be a 3-pole 4-wire grounding receptacle. It will be a 125/250 volt rating NEMA number 14–50R. The red and black wires connect to the X and Y terminals, the white wire to the W terminal and the ground wire to the G terminal.
Do wires need to go to all the screws in a 120 receptacle?
No, just black on brass colour and white on silver colour screws. If you look closely you will see what is called a tie bar connecting the two screws together.
How do you extend the electric outlet at the basement?
Parallel connect the new receptacle to a receptacle in the existing circuit. Black (hot) existing to black (new), white existing to white (new), ground existing to ground (new). Make the ground wire coming into the new receptacle box longer so that it can be looped around the ground screw located in the receptacle box first and then connect to the receptacle without having a break in the wire.

Which wire goes on the ground fault receptacle?
In normal home wiring the black and white supply the circuit voltage. The green conductor connects to the green screw. The black conductor connects to the brass coloured screw and the white conductor connects to the silver coloured screw. There are additional terminals on the receptacle that connect to the down stream side of the circuit. By making these connections on the GFI receptacle all downstream normal duplex receptacles are also protected.
Where does the white wire connect on a six volt battery?
You don't say what you are connecting to the battery. If you have a black and white wire the best guess would be white to negative terminal and black to positive terminal. If you were connecting a 6V light bulb it really doesn't matter.

Can you use one length of 3-wire cable to provide electricity to 2 separate circuits?
In countries that use a single phase split secondary service you can. In modern homes this is the type of circuitry that is used for kitchen split receptacles. On the receptacle the tie bar is removed from the "hot" side of the receptacle. A red wire of the three wire cable is placed on the upper terminal of the receptacle. A black wire of the three wire cable is placed on the lower terminal of the receptacle. The white wire is placed on the opposite side of the receptacle under the silver coloured screw. This will give you a full 15 amps capacity on the top portion of the receptacle and a full 15 amp capacity on the bottom half of the receptacle.
