Metalic Conduit for grounding

[Zyb]

Hi,

can someone explain why I can't use metallic conduit for grounding conductor? Thanks

Can you explain what we're looking at? Is that a connection from the steel to a CEE in a footing?

What kind of grounding conductor is represented? A Grounding Electrode Conductor, a equipment grounding conductor, or some other type?
