\\n\\n<\/p>\nFAQs<\/h3>\n
Yes, CPC refers to the conductor that performs the grounding function in a circuit.<\/p>\n
Yes, when properly bonded and earthed, the steel armour can act as the CPC.<\/p>\n
Typically green\/yellow<\/strong>, though in some cables (like T&E), it may be bare copper and must be sleeved.<\/p>\n
