In North America the white neutral wire is never switched. This is because a split single phase secondary system is used. Opening a neutral could put two branch circuit loads in series with each other.

Is red neutral or live in a 240 volt system?
The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
Are there electrical colour codes for wiring in India?
Red, Yellow and Blue for Live. Black for neutral and Green for Earthing
What colour code for 3 pin plug in NZ?
The live wire is brown in coulor while the earth wireis green and yellow in color and neutral wire is blue in colour. Uses of these three wire: Live wire:It's connected with fuse.It carries a voltage which drives electric current through the electrical appliances. Earth wire:It is a safety device and protect us from electric shock. Neutral wire:It offers a return path by electric current.
Which colour wire is live in UK wiring?
In a flexible cable, the brown is the "line" voltage and blue is "neutral", often tied to ground at the mains panel. In fixed cables, i.e., "behind the walls", the UK wiring standard changed in 2004, where it now MATCHES the flexible cable: brown is line, blue is neutral. Prior to that, blue, red or yellow were acceptable LINE conductor colors and black was neutral.
What happen when neutral connect to live?
short circuit
What colour wire is switched live feed on a car stereo?
Yellow
Is red neutral or live in a 240 volt system?
The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
Do live colour xxl hair dyes have semi permanent as-well as permanent?
yes
Why do the electric test pen lighted up at live only not at neutral when AC supply switched on?
it measures the ionization of the air.
Where do you connect the fuse cable wire from a car stereo you have a Red wire that is the live a black wire that is earth and a yellow wire that is for fuse where do you connect the yellow wire too?
Red goes to a switched live i.e one that is only live when the ignition is switched on. Yellow goes to a permanent live i.e one that is always live whether the ignition is n or not, like the cigarette lighter, and maintains the station configuration memory. However, a modern car should have a pre-wired Din connector and a local motor factor will have the corresponding universal adaptor for your radio; connect colour ro colour (inc speaker wires) and plug it in !

What colour earth neutral and live in armoued cable?
All depends on what country you are in, wiring standards and cable type. Industrial cable in the UK is. :- Red = Live Black = Neutral Copper wire = earth. (add Green/Yellow striped sleeve at junctions.) Domestic is:- Brown = Live Blue = neutral Green/yellow stripe = Earth Europe Black = Live Blue = Neutral Brown = Earth
Access to the circuit panel is locked- is it possible to safely change a bad wall switch without shutting off power?
No. If it's a light switch then it will have a live wire, a switched live and an earth. If it's a switched socket then it will have a live wire, a neutral and an earth. Either way the switch needs to be isolated from the mains before the switch can be disconnected.
Can you replace wall light switch with a PIR switch if Wall switch has usual live neutral and earth but PIR has live in live out and neutral.?
An ordinary light switch does NOT have any neutral -- it only switches the live wire. Some installers use the white wire as a "switched" wire to the light fixture, where the power cable went to the light and a separate cable went to the switch. Technically, the white wire should have been marked with red or black tape at each end, to signify it is not neutral - it is either live or off. In that case, you would not be able to use a PIR switch because there is no neutral, which is necessary to provide power to the electronic circuit in the PIR. You would need to rewire the switch with a new power cable from the branch circuit. The you have the live and neutral wires in the outlet box, connect them to the PIR, and run the pigtailed neutral and the switched live (and pigtailed ground) to the light fixture (where you would disconnect the other power cable completely and cap the ends separately).
What are the needs for colour coding of cables and wiring including live neutral and earth colours?
Australia: ANZS3000 Active= Red or Brown Neutral = Black or Light Blue Earth = Green or Green and Yellow stripe
What position would you find live electrical wire?
You would find a live electric wire, with a neutral and usually also an earth wire, in any place where electricity is used. The wires are colour coded differently in different areas but in Europe live is brown, neutral is blue and earth is green/yellow.
How do lethal mutations and neutral mutations differ?
Lethal mutations cause such a radical change that the organism cannot live with it and dies. A neutral mutation is a simple change that does not affect the organism in any way, such as a new eye colour.
