Electricity is an essential and one of the important types of energy and power that we are using in our daily lives. It is the significant component for virtually every step in manufacturing and most other industries. It has become an essential part of modern life and economy of any country which depends on it. Electricity is being used for residential, industrial and commercial along with transport etc.
If electricity is being used throughout the day, it has the potential to cause many issues and if something is not wired properly, it can result in injuries, deaths as well as fire or many other problems. That’s why there are wire colour codes in order to ensure proper safety for those who are working around these kinds of dangerous situations.
Types of Wire Colour Codes: There are many different wire colour code standards, so it is essential to know which one should be used in which situation. These codes can vary country to country that’s why learning is important about different options that can be used in a situation is essential for a workplace safety.
Wire Colour for DC Power: The wiring for the DC Power can be two or three wires which are as follows:
- Positive: Red is the wire for positive current.
- Negative: Black is the wire for negative current.
- Ground: White or grey is the colour for ground wire.
AC Power: This power is available in many different types and they are based on carrying of volts by the wires. For the AC Power, following wire colour standards are used and it is essential to know the type of wiring and their multiple phases.
- Phase 1 – It should be black.
- Phase 2 – It should be in red.
- Phase 3 – It should be in blue.
- Phase 4 (Neutral) – It is neutral wiring that should be in white.
- Ground – It can be in green or green with a yellow stripe.
In some opposite situations, there will be higher voltage in one phase in comparison to the others and these are known as high leg connections.
Particular Volt Wire Colour Standards: These are the high voltage connections (277/480) which are common in multiple manufacturing and other industrial areas. We can get these colour codes essential due to potential for deadly electrocution.
- Phase 1– This wiring should be in brown.
- Phase 2 – it should be in orange.
- Phase 3 – It should be in yellow.
- Neutral – It should be in grey.
- Ground – It should be in green or green with a yellow stripe.
