Beyond that are general industry accepted rules about wire color that indicate their purpose. Green yellow some systems will use a green wire with a yellow stripe for the ground.

What color is the ground wire. A ground wire is used as a protective measure. Bare if the wire is not primarily green it may also just be a bare copper wire. Green in the usa most ground wires will be green or at least primarily green. Yet in usa in ac house wiring black is the hot live conductor. Note that the outlets screw terminals are certain colors. The protective ground must be bare green or green yellow striped.
The recommendations in table below are by wiles. Negative the wire for the negative current is black. Loosen each terminal screw hook the wire around it and put the screw down tightly. Red wires are commonly found in sheathed multi conductor cable. The black hot and white neutral wires carry the current and the copper wire is the ground. The coloring is as follows.
The color standards for ground wires are as follows. The purpose of green wires is to ground an electrical circuit. Ground the ground wire if present will be white or grey. The white wire goes on the silver screw. And just because a wire is grounded doesnt mean its safe. They connect to the grounding terminal in an outlet box and run to the ground bus bar in an electrical panel.
The bare copper or green wire goes on the green screw. The white wire goes on the silver terminal the black wire on the brass one and the green wire on the green one. Ground wires return fault current to earth ground protecting the individual from electrocution. The national electrical code nec says that white or gray must be used for neutral conductors and that bare copper or green wires must be used as ground wires. However all electrical wires regardless of their function may carry an electrical current at some point and should be treated with equal caution. However common practice per local electrical inspectors is for the first hot live or active wire to be black and the second hot to be red.
These are called travelers and typically used for two way switch wiring. One is silver one is brass and one is green. Positive the wire for the positive current is red. The spruce 2018. In some context the ground conductor is bare or green but just because a wire is bare doesnt mean its grounded. The question needs more context.
When you see either a green wire or a bare copper wire you can be sure it is a ground wire. When youre done join the two halves of the plug casing and tighten the screws to hold it together. Hot active wires may be any other colors except these. Blue and yellow wires are sometimes used as hot wires and as travelers green wires and bare copper wires are ground wires and white and gray wires are neutral. In this way green wires act as a failsafe giving electricity a place to escape into the ground if a live wire within the circuit touches metal or something else conductive.
