              What do the Different Colors in the Cable Represent?


              The red wire is the fire wire, the blue wire is the neutral wire, and the yellow or yellow and white wires are the ground wire.

              The most commonly used yellow, green, and red represent phase lines. It can also be said that the line of the fire line is charged.

              Blue represents work zero, and can also be said to be a zero line. This line is generally uncharged, but there are also times when there is electricity. That is, when the zero line is broken, the line is charged. The two colors represent the ground line. This line is the safest. The function of this line is to help the leakage trip after the zero line break.
