Which Colour wire goes to the Earth pin?
The cable
| Colour | Wire | Function |
|---|---|---|
| Brown | Live | Is held at a voltage of 230 V and provides the current |
| Blue | Neutral | Completes the circuit |
| Green and yellow stripes | Earth | A safety wire to stop the appliance becoming live |
Can I connect Red and black wires together?
Red Electrical Wires These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire.
Can you put a 3 pin plug on a 2 pin appliance?
If your appliance currently have a 2 pin plug it means it is double insulated, does not have exposed metal. Therefore it is safe to fit a 3 pin plug in place of a 2 pin plug however employ your local electrician to double check and fit the 3 pin plug.
What are the color standards for electrical wiring?
For wires that will be 120, 208 or 240 volts, the following wiring color standards are used. It is important to note that with this type of wiring, there are multiple phases in place, each of which will get its own color wire to make it clear what it is for those working on it.
What kind of electrical wire is orange in color?
While rare, they can be identified by looking for a wire that is marked with orange, which will be the higher voltage wire. 277/480 Volt Wire Color Standards These high-voltage connections are quite common in many manufacturing and other industrial areas.
What are the colors for Phase 3 wiring?
Phase 3 – Phase 3 wiring should be yellow. Neutral – Neutral wires should be grey. Ground – Ground wiring should be green, or green with a yellow stripe. These are the wire color coding standards that are used in the United States. In Europe and other countries, there are different standards in place.
What are the different colors of AC wire?
Ground – The ground wire (if present) will be white or grey. AC Power (120/208/240 Volts) AC power comes in many different types based on how many volts the wires will be carrying. For wires that will be 120, 208 or 240 volts, the following wiring color standards are used.

How can you tell the polarity of a wire?
These wires are often held together by a clear casing, so they’re easy to determine the polarity of each side quickly. If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive.
Why are black and red wires used in electrical wiring?
These are the most common colors used in electrical wiring. Other color combinations, such as striped wires, may be used for other applications. Remember, black and red wires are always hot, meaning they are source wires that carry power from the electric service panel to a destination, such as an outlet or a light.
While rare, they can be identified by looking for a wire that is marked with orange, which will be the higher voltage wire. 277/480 Volt Wire Color Standards These high-voltage connections are quite common in many manufacturing and other industrial areas.
