Black (neutral) Red (live) Green and yellow (earth)
How do you tell which wire is positive and which is negative?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.

Why is electricity important?
Electricity is an essential component for virtually every step in manufacturing and most other industries. In most facilities, the electricity will come in at one point in the building, and then be distributed to just about every corner through a series of wires. Even the tools and machines that are used are filled with wires ...
What happens if you don't wire properly?
If something is not wired properly, it can result in injuries, deaths, fires, and many other problems. This is why there are well-established wire color codes to ensure those working with an around this type of equipment can ensure everything is wired safely and effectively.
Is it safe to use electrical wires?
Another important thing to keep in mind when looking at the safety of electrical wires is the data wiring in a facility. Cables that are used to transmit data for computer systems are often thought to be harmless since they are carrying information rather than electricity.
Why is it important to label wires?

Can you put yourself at risk without proper guidance?
Without proper guidance, training, and documentation, they could put themselves or the entire facility at risk if they need to interact with wiring in any way. Anyone who will have any exposure to electrical wires should have at least a basic understanding of the wire color codes.
What color wires are used for a PG?
The mandatory colors for power wiring in National Electric Codes (NEC) are Green, Bare or Green/Yellow (Yellow Strip or band on Green) for Protective Ground “PG” and White (alternatively Grey) for Neutral Wire. Any other colors expected the above mentioned can be used for Live (Line or Hot) wires.
Which countries use the IEC color code for DC?
Other Countries like China, Russia, KSA and UAE now follow the IEC Cable color codes for DC. But don’t trust the cable insulation colors in these areas as electricians use old as well as new color codes for both AC and DC.
Does Russia use gray or purple?
Russia was following the same wiring color codes as China before but they adapted the IEC with little bit changes i.e. in a three phase system, they may use purple or gray color instead of gray in IEC. As things are little bit changed in Russia, so one must follow the tester before going in the mess.
A brief history of wiring color codes
It took until 1928 for wire color coding to make its debut. The National Electrical Code® (NEC) was the first to reference it, and today continues to set the standards for the electrical industry. Following a uniform color code makes it easier to assess electrical wiring, and ensure safety among licensed professionals and homeowners alike.
The NEC wire color coding standards
Though there are international wire color codes, the U.S. follows the National Electrical Code ® (NEC). The code is identified as NFPA 70 ® because the NEC is sponsored by the National Fire Protection Association. Though not a federal law (states can choose to adopt it), it is approved by the American National Standards Institute (ANSI).
3-Phase Wire Color Codes
Whether adding a home appliance or industrial machinery, you’ll need to know these electrical wiring color codes. In the U.S., these color-coded wires carry power from a circuit breaker to a device.
