Question

What is the color code for the insulation on the earth wire?

Answer 1

1. Insulation term is generally used to describe material that creates barriers for transmission of heat and electricity.
2. Color coding of wire helps us to identify the circuit and also provides safety.
3. According to the new international convention
   $\left(a\right)$ Earth wire is yellow or green in color
   $\left(b\right)$ Live wire is brown in color
   $\left(c\right)$ Neutral wire is in light blue.

Hence, the color code for the insulation on the earth wire is yellow or green in color.
