If you have been working with IEC standards or its derivative standards like the AS, it will be strange for you to learn that NEC and a derivative standard like the PEC use different colors for the insulation of grounded or earthed conductors.
|Term||NEC / PEC||IEC / AS|
|Identificaton||(1) A continuous white outer finish.
(2) A continuous gray outer finish
(3) Three continuous white stripes along its entire length on other than green insulation.
(4) At the time of installation, by a distinctive white or gray marking at its terminations. This marking shall encircle the conductor or insulation.
PEC 2017 - Clause 18.104.22.168
Interface between these different standards will be very difficult. Thorough planning is required.
