because we "bond" and "ground." we do them at the same time, and they are both important, for separate reasons.

An Equipment Grounding Conductor is for clearing a fault. A bonding conductor could be for anything.

Grounding Conductor, Equipment (EGC). - A conductor path(s) that is part of an effective ground-fault current path and connects normally non-current carrying metal part of equipment together and to the system grounded conductor, or to the grounding electrode conductor, or both.
it's more than just a wire bonding conductor. it's the entire equipotential bonded system, including conduits and other metal framework.

Equipment bonding conductor is really the correct term....I proposed that a number of cycles ago, and a majority of Code Making Panel 5 approved that change, however it takes a 2/3s majority to change the code and the vote was one vote short of being 2/3s. The Canadian Code does use the term equipment bonding conductor and not equipment grounding conductor.
The word grounding in the existing term is the reason many think you can just connect it to earth and it will be safe.

The reason so many think ground = safe is all emphasis put on "grounding" things. You can't splice a grounding electrode conductor. Specs still call out for ground rods for street lights. Highly paid engineers want you to drive ground rods in the shape of a triangle. The NEC tells us you have to try and drive a ground rod straight down and see if something stops it before you can drive it at an angle. I see ground rods installed at the stupidest places like a 500V DC EV fast charger.
You want people to stop thinking grounding is so safe more holy than baptizing babies get rid of all the foolish requirements associated with it.

Yeah, but the ground or earth is probably the least consequential component in the entire system. "Ground-fault" itself is a term that is rarely the case. It is usually a grounded conductor fault and ultimately, even when the fault is to the earth its final destination is the grounded conductor.

As Don said EBG is a more correct term but there has probably been 100's of Public Inputs and old Proposals to change it which have all been rejected. This seems to be one time where the CMP's don't want to reinvent the wheel when they actually should.

In ground pools require bonding conductors that are not required to be EGC. Cell sites have gobs and gobs of bonding conductors on every piece of metal equipment on the site. FAA requires an extra bonding conductors on the outside of every run of flexible conduit. While all of them may wind up as part of a fault clearing path none of them are part of the NEC requirements for Equipment Grounding Conductors.
