In our Conlok conduit installation video, we explored the electrical continuity of the full electrical installation. In most electrical installations today, most circuits are wired with a dedicated circuit protective conductor (CPC). Do you have to include a CPC conductor when using a metal conduit?

We'll explore the use of steel conduit as an earth conductor and how it's applied to multiple circuits contained within the same conduit or trunking.
