What do wire colors mean?
Red Wires – always assume they are live. You'll find red wires present in 220-volt circuits. While red is secondary to black, it's often used in appliances like smoke detectors. Yellow Wires – always assume they are live if you have power. A yellow wire is used as a live wire pulled through a conduit.

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.

What is the color code for a three phase motor?
Conductors of a three-phase system are usually identified by a color code, to allow for balanced loading and to assure the correct phase rotation for induction motors. Colors used may adhere to International Standard IEC 60446, older standards or to no standard at all and may vary even within a single installation. For example, in the U.S. and Canada, different color codes are used for grounded (earthed) and ungrounded systems.
What color is used for grounded conductors?
National Electric Code has color requirements for grounded conductors, ground and grounded-delta 3-phase systems which result in one ungrounded leg having a higher voltage potential to ground than the other two ungrounded legs. Orange is only appropriate when the system has a grounded delta service, regardless of voltage.

In United States and Canada, different single phase and three phase voltage levels are available i.e. single phase voltage is available for domestic and residential applications while three phase voltage can be used for industrial and commercial applications.
Can a motor be connected to a three phase supply?
In Three Phase Supply, motors and large electric heaters can be directly connected to the three Phases (Neutral is not needed in all cases) while in Single Phase, load circuits (light, fan etc.) can be connected in between Phase and Neutral through proper protective devices e.g. earthing/grounding wire.
When did the colour code change for electrical cables?
