As of March 2011, the European Committee for Electrotechnical Standardization ( CENELEC ) requires the use of green / yellow colour cables as protective conductors, blue as neutral conductors and brown as single-phase conductors.

Also, the unbalanced current due to lamps and small motors in the appliances was small compared to the rating of the conductors and therefore unlikely to cause a large voltage drop in the neutral conductor.
33.
It is good practice to use four-pole circuit breakers ( as opposed to the standard three-pole ) where the fourth pole is the neutral phase, and is hence protected against overcurrent on the neutral conductor.
34.
In a polyphase ( usually three-phase ) AC system, the neutral conductor is intended to have similar voltages to each of the other circuit conductors, but may carry very little current if the phases are balanced.
35.
Using the neutral conductor for grounding the equipment enclosure was considered safe since the devices were permanently wired to the supply and so the neutral was unlikely to be broken without also breaking both supply conductors.
36.
As per Indian CEAR " neutral conductor " means that conductor of a multi-wire system, the voltage of which is normally intermediate between the voltages of the other conductors of the system and shall also include return wire of the single phase system.
37.
Drawing heavily from Bruno Latour, Goeminne and Fran�ois'work serves to problematise the representational work done by science : science is neither a neutral conductor of material reality that produces facts , nor should its legitimacy to speak on behalf of nature escape scrutiny.
38.
In places where the design of the plug and socket cannot ensure that a system neutral conductor is connected to particular terminals of the device ( " unpolarized " plugs ), portable appliances must be designed on the assumption that either pole of each circuit may reach full voltage with respect to ground.
