The c.s.a. and the protection of the neutral conductor, apart from its current-carrying requirement, depend on several factors, namely:
- The type of earthing system, TT, TN, etc.
- The harmonic currents
- The method of protection against indirect contact hazards according to the methods described below
The color of the neutral conductor is statutorily blue. PEN conductor, when insulated, shall be marked by one of the following
methods:
- Green-and-yellow throughout its length with, in addition, light blue markings at the terminations, or
- Light blue throughout its length with, in addition, green-and-yellow markings at the terminations
