Is white wire neutral?
Yes. But the white wire can also be a hot or switch leg if marked correctly. But for the most part white is netural.
The ribbed wire on a lamp cord is the neutral wire. On an extension cord there is no rib but the neutral wire is white in colour.
No, the white wire is neutral It depends on how many wires you have. If you have just a black and white, the white is hot. If you have a black, red, white, the white is the neutral
What to do with the white wire in track light with black green and white wires if the house does not have a white one?
The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire. You will have to determine which is hot and which is neutral. You can easily do this with a voltage tester. The wire that lights the tester is the hot. When you wire the light simply wire the hot to hot, and the… Read More
The neutral wire and power wire are never connected together.
In Brazil, a neutral wire has green and white stripes.
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
The black wire is hot and the white wire is neutral.
Just cap the white wire off and fold it up in the back of the box, out of the way.
The black wire should be the "hot" conductor and the neutral is the white wire. (assuming it is wired correctly in the panel which it likely is.
Typical home wiring will have one hot wire, one neutral wire, and one ground wire per circuit. An open neutral would indicate that the neutral wire, usually white wire, is broken.
A light switch has three wire colors red and white and green which is the hot wire and which is the neutral?
Red is hot Green is ground White is neutral
The black and white (neutral) wires connect to an unswitched voltage supply. The red wire and the same white (neutral) wires connect to the load.
White is typically neutral and black is hot. If you are talking about the bare wire, that is ground.
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
When using these types of testers always test the black to white wire and then black to ground wire. If the tester indicates there is a voltage to ground and not the white then the neutral white wire is open somewhere in the circuit.
Connect to the circuit neutral wire which should also be white.
In standard residential wiring there is a black (hot), white (neutral) and bare wire (ground). There must be a neutral, so not sure what you mean. The neutral and ground are bonded to each other at the main electric panel.
Don't confuse the white colour of wire and the use of the neutral wire. There are installations where the white coloured wire is used as a return hot wire. In home installations, switches use the white wire to return the hot to the lighting load. In 240 installations the return leg of the 240 volt load is returned on the white wire. Code states that in both instances the white wire has to be re… Read More
the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
It is the return wire for the hot side of the circuit (the black wire).
The wire that connects to the outer, screw section of the socket is the neutral in a two wire lamp cord. This neutral wire also connects to the larger of the two blades in a polarized plug -- if one is used. The smooth wire connects to the black hot wire and the wire with ridges connects to the white neutral wire.
The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
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.
The white wire would go to the neutral bar. Just be sure of the shunt trip voltage required for the breaker and land the white wire on the appropriate neutral bar in the correct panel.
If the cord is not zipcord, but has individual wires the neutral is the white wire and the hot is the black wire (if the 3rd wire ground is present it will either be the green wire or a bare uninsulated wire).
On a light switch the white wire is neutral. All the neutral white wires are tied together under a wire nut and pushed back inside the box. The white is not connected to the switch.
The black wire originating from a breaker box or fuse box is the live wire. However, in certain cases, the grey (or white) neutral wire can also be live. For example, the black wire may feed a lighting outlet, and if the neutral wire is broken on its way back to the neutral bar in the panel, then the neutral wire from the lighting outlet will be hot, because there is an electrical path from… Read More
If the breaker box is wired correctly the Black wire is hot, white is neutral. However, because of the practice of using a common neutral, it's impossible to say that the white wire is not "hot" at any given time.
US NEC: The neutral line is the white wire. Coming from the pole, it is the ground wire.
So that you will know it is the earth ground wire and not the neutral wire or the hot wire. The neutral white wire is not necessarily connected to the same place as the earth ground wire. It is also bare because it does not matter if it touches a metal exterior since it is supposed to be connected to that anyway for safety. Both the neutral white wire and the hot black wire are… Read More
In North America any coloured wire except white and green can be designated to be a "hot" wire. White is reserved for the neutral wire of a circuit and green is reserved for the ground wire in a circuit.
black is hot (live), white is neutral, or common
It just means that the bare wire is insulated by a non-conducting coating. In home wiring the typical circuit has a black wire (Hot), a white wire (Neutral) and a bare wire which is ground.
If you are asking about the electrical cord on a lamp, the black wire with the white stripe is the neutral conductor.
White (neutral), in the USA. The international standard color for the neutral wire insulation is blue.
The white wire is always identified as a neutral wire. The only time you will find the white wire "hot" is in residential home wiring. This will be the return wire from a light switch back up to the light fixture. Code specifies that this conductor has to have a coloured tape identifier to show that it is not a neutral but a current carrying "hot" conductor.
black - hot red - hot inverse phase white - neutral/return green - safety ground
No, the colour white is used to identify the neutral in electrical distribution systems.
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
If the voltage source is at the fixture box, the wire will be a two wire that goes to the switch box. The colour coding should be, black wire going to the top of the switch as a "hot" feeder and the return from the switch to the light fixture will be the white wire. The white is not a neutral and should be identified as such. This is done by wrapping black tape around… Read More
NO,WHITE IS FOR NEUTRAL ON 120 TO 240 VOLT SYSTEMS bLUE IS A LINE VOLTAGE COLOR TO LET YOU KNOW WHAT YOU ARE WORKING WITH. IF YOU USE IT IT MUST TAPED WHITE @ JUNCTION POINT TO iDENTIFY IT AS A NEUTRAL
The standard is: the white wire is "Neutral", and the black wire is "Load".
White is the neutral wire. Black is hot, green is ground.
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
white wire = neutral bare wire = ground black wire = line voltage red wire = returned from a switch, or the other phase of line voltage in order to supply 240VAC
In theory this should only ocure at the main junction box ... but if EVERYTHING is done right, then it is safe - but not in code.
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.
US the black wire is your hot the white wire is your neutral in other words your load and the bare copper is your ground wire. UK The brown wire is live, the blue is neutral and the Green/Yellow is earth.
In the US and Canada, the white wire is universally the neutral. The "hot" wire can be red or black, both are used. Maybe the manufacturer was able to get a good deal on red wire.
The electrical terms of positive and negative usually refer to DC installations. In AC installations, the terms used are "hot" and neutral. In instrumentation analogue installation the common methodology is to make the white wire positive. In the wiring of homes the white wire is always used as the neutral conductor.
