Greenfield conduit grounding?

Question

if greenfield conduit is not suitable for grounding purposes as it has poor conductivity, then what if it becomes energized? Let's say it's a long length of continuous greenfield. It wouldn't pass enough current to trip a breaker, or at least this is what we are supposed to assume when designing a greenfield system. Therefore, it would remain energized and be a hazard for anyone who may touch it. And the energy bill would be pretty high at the end of the month. Wouldn't we be better off using non-mettalic flexible conduit instead? Why is greenfield even sold for purposes more than 6 feet (allowed grounding distance)?

Answer 1

Run an additional equipment grounding conductor attached tio the outside of the flexible metal conduit grounding both ends of your fitting connections(i.e by using a bondable ground bushing. or run it internally and repeat all the steps listed for the outside application.

Proper bonding of any electrical system throughout is vitally essential.

Answer 2

When in use, it should always have an internal ground wire inside the conduit connected to it at both ends.

"And the energy bill would be pretty high at the end of the month" I think you need to review your classes. It would see current only in the event of a fault.
