You may have seen colourful wires in your home. The colour coding of wire is not for decorative purpose but for safety, as each colour has a crucial role to play. Every colour defines a specific function in the complete electrical system.Electric wires conduct electricity by serving
as a path for an electric current.Universally, a colour code is accepted by all countries with a small difference here
and there. In India, we follow the basic colour coding which is as follows:
Red, brown or yellow : Live wire
Black/Blue : Neutral
Green : Earthing
An electrical system is a complex system with different devices equipped for a specific amount of current.Therefore different wires are used to beef up its efficiency and protection.
A Live wire or a hot wire is used to carry current to the device to run it. The most common colour used in India is red. It carries current that runs fan, lights etc. A neutral wire offers a return path to the
current when it is in excess Sometime the voltage fluctuates causing a huge amount
of current to flow. Neutral, as the name explains, neutralizes by buffering the extra current and sending it backward. Earthing wire is for safety and avoids
electrocution. This wire is very important
for electric devices made of a metal that conducts electricity eg: aluminum. By
chance a device conducts electricity; it may cause an electric shock. An earthing
wire will complete the circuit by carrying
the current to ground thus avoiding electric
shock dangers.
This colour code may differ therefore it is
advisable to hire a qualified electrician to
deal with faulty wires. Live wires must
never be touched bare handed. On a lot of
occasions, the earthing wire may be
missing or may not be installed in the
electric system. We would emphasize on
its installation everywhere. It helps in
minimizing electric shock dangers.
