Even the tools and machines that are used are filled with wires that are used to conduct the electricity to perform whatever action is needed. Ground - Ground wiring should be green, or green with a yellow stripe. There are multiple colors used for different wires and cables in different regions for AC (alternating current) Single-Phase , Three-Phase and DC (Direct Current) for design and installation based on the local codes, rules and regulations. Hot (active) wires may be any other colors except these. Those who don't work directly with wiring all the time also need to get this type of training, and in many ways it is even more important.
