Understanding Electrical Wiring Color Code Chart in the UK
The wiring system of a home plays an essential role in the safety and functioning of the electrical equipment and systems. Fortunately, advancements in technology have made it easier than ever to keep your wiring system in order and safe. One of the most important ways to do this is to be aware of the electrical wire color code chart in the UK.
Electrical wiring color codes are standardised over many countries and regions internationally, so it's important that one is familiar with them to stay compliant with safety standards. It can be daunting to understand all the codes, but knowing the basics of a wiring diagram and how colors are used to identify what type of wiring is involved will make it easier to follow the chart and understand the necessary precautions when dealing with the wiring system in a house.
The Different Colors Used in Electrical Wiring
In the UK, some common colors used for electrical wiring are black, red, green, yellow, blue, and white. Each color has a corresponding function and serves as an indication for the purpose of the wiring.
- Black – this is usually used for live wires with power.
- Red – this is usually used for the neutral wires.
- Green – this is typically used for the ground wire.
- Yellow – this is usually used for load wires.
- Blue – this is commonly used for switched live wires.
- White – this is generally used as a neutral wire.
Understand the Electrical Wiring Color Code Chart
Understanding the wiring color code chart is essential to be able to correctly map and wire your electrical system. A wiring diagram should be consulted when dealing with any wiring problem as it provides a pictorial representation of the wiring system.
The wiring color code chart contains five columns, including the first three colored columns and the last two columns for numeric values. The first column is for the code that each colour represents. The second column indicates the type of wiring, such as live, neutral, or ground, and the third column is for the conductor size in millimeters squared. The last two columns indicate the current rating in amps and volts.
Safety First!
It’s essential to use the correct colors for safety reasons. People who are unaware of the proper color codes could end up connecting two wires of different colors together, leading to disastrous consequences. When dealing with any wiring project, it’s always best to consult a professional, particularly if you aren’t familiar with the electrical wiring color code chart in the UK.
