Equipment bonding jumper

[cppoly]

I’m getting caught up on the definition for an equipment bonding jumper which is “The connection between two or more portions of the equipment grounding conductor.”

In more text from the NEC it says, “equipment bonding jumpers are used to connect the grounding terminal of a receptacle to a metal box that in turn is grounded via an equipment grounding conductor in the form of a metal raceway system.”

So if an equipment bonding jumper makes one connection to the equipment grounding conductor, why is the definition saying “two or more portions”. Where’s the second portion?

In that scenario it would seem one portion is the device yolk and the other is the box.

bonding jumper is assuring there is continuity between the two components it connects to.

So if an equipment bonding jumper makes one connection to the equipment grounding conductor (EGC), why is the definition saying “two or more portions”. Where’s the second portion?

Inside the "receptacle device" there is an equipment grounding conductor (EGC) path between the contact of the plug in and the green ground screw on the yoke. That path inside the receptacle device is the SECOND portion of EGC.
