What Is A 4 Core Armoured Cable Used For?

Generally speaking, amour provides a mechanical shield that enables any armoured cable to tolerate high-stress situations. Thus, it is accurate to say that a 4 core armoured cable is ideal for high-stress wiring applications. More specifically, this type of cable is perfect for low voltage wiring applications and low current signal applications. What are some of the advantages of using an armoured 4 core cable?

Well, the main advantage of this type of cable is its conductivity. A 4 core wire delivers twice the amount of current that a two-core electrical wire carries. Understandably, a 4-conductor cable is thicker and more expensive compared to a single core or two-core wire. You might be tempted to go for the cheaper option, but I must advise you to consider the cable’s quality rather than its price. You will be surprised at the efficacy of a 4 core cable. Still, you need to consider the cable specifications before making your final decision.

Electricians worldwide are accustomed to following a particular predefined colour code when performing wiring tasks in houses, commercial estates, and industrial panel boards. Any attempt to carry out any form of wiring without a comprehensive understanding of cable colour codes may end in a disaster. Therefore, it is crucial for you to comprehend the colour codes of a 4 core cable fully. What exactly is the colour code of this type of cable?

The question posed above does not have a straightforward as most of us imagine it does. Electrical wiring codes that cable manufacturers follow tend to vary depending on the standards they follow. The image below shows a general representation of cable colour codes in China;

It is important to note that these colours and their meaning may change depending on the cable’s manufacturer and country of origin. It is advisable to seek the assistance of your local wiring expert in the interpretation of colour codes. It is also advisable to avoid installing a 4 core cable on your own if you don’t have any electrical wiring expertise.
