It could be for an IG, if they used a plastic box on the other end the EGC would already be isolated.I'm going with someone tried to do an isolated ground
Right. Every circuit is an IG circuit when wired with non-metallic components.It could be for an IG, if they used a plastic box on the other end the EGC would already be isolated.
It is 4 conductors or more commonly called three wire with ground.Where do you see 4 conductor NM?
I don't believe an EGC can be anything other than bare, green or yellow with a green stripe. And you cannot reidentify anything that small with green tape either. So it doesn't belong there.
