What is the difference between grounded and grounding conductors?

This was on quiz 3 of electrical-The grounded and grounding conductors ________________ bus in the service panel. (you answered “can share a common”)…what is the difference between grounded and grounding conductors?? why does the course often say things that make no sense??

Grounded conductors are the neutrals. Grounding conductors are your equipment grounds (think third prong on a receptacle).


Did it say your answer was correct?

Also, more importantly, knowing the difference between a grounded and grounding conductor is something you need to be very familiar with as a home inspector. I recommend to do as much research and studying as you can until you completely understand their differences and what their purpose is.


Exactly… …

Grounding conductors would only carry current in the event of a fault. GroundED conductors always carry the neutral current.


Yep… …Thanks, Jim

This is the terminology the NEC came up with to describe the three conductors. Each is described by its relationship to ground. The ungrounded conductor is the black wire in your typical 120v outlet. Colloquially called “hot”. The grounded conductor is the white wire, we call neutral and the ground conductor is the green equipment ground.

Grounding conductors are more precisely described by the NEC as equipment grounding conductors or EGC’s (IMO they should not be called grounds but that’s a common slang term). If your wiring method is NM cable they will almost always be the bare uninsulated conductor within the cable. They may also be green insulated. Grounded or neutral conductors (unless within a service entrance cable) will be insulated and identified by white or gray insulation or some other marking.
