Name the colour code of the wire which is connected to the metabolic body of an appliance?
Solution
Hint There are three wires which are connected to the metallic body of an appliance, these are: live wires, neutral wires and earth wires. We need to maintain the colours of these wires.
Complete step-by-step solution :
Colour code is a system for displaying information by using different colours .
The electrical appliances that we use at our homes are connected to three wires . These wires are live wire, neutral wires and earth wires
With the help of colour codes of electrical wires, they can be easily and safely identified. Understanding of three electrical wiring colour codes is important as the properties of different wires may be different from others and wrong fill placement or connections may be hazardous.
In simple words, we can say that live wire brings the current to our households. Due to this reason it is at high voltage. Neutral wire completes the circuit and is the return wire which connects the appliances to that terminal of the source of electric supply which is earthed.
Earth wire usually carries no current. It is a safety wire and connects the metal case of the appliance to the earth .
WIRE | COLOUR |
---|---|
LIVE | Brown |
NEUTRAL | Light blue |
EARTH | Green or yellow |
Note:-
In some books the colour code may even be mentioned as
Red for live wire
Black for neutral wire
Green for earth wire
Do not confuse these two colour codes. This code is written as per the old convention and so, it is no longer used. The one mentioned in the solution is written as per the new convention.
