Grounding terms

[m sleem]

Since i am not an american engineer so, some of the grounding terms is not clear for me, please correct me if i am wrong,

- "EGC" the grounding conductor that bonds the electrical equipments together and provides an alternative path with low impedance during fault current
- "GEC" the grounding conductor that bonds the electrical equipment to grounding rod/water pipes/(nearest grounding electrodes)
- "Bonding jumper" the grounding conductor that bonds the metal parts together to provide a continuous path during fault current (sometimes getting confused with "GEC")

Also in IEC standards (may someone confirm or correct):
- "EGC" is "PE"
- "GEC" is "Earthing cable"
- "Bonding jumper" is "Equipotential bonding"

The lower case word 'ground' is the most overused, misused and misunderstood word in the electrical vocabulary.
The NEC defines 'ground' as the earth (Planet Earth), yet uses it in grounding and grounded conductor which have little to do with Planet Earth.

In electronics 'ground' can refer to any of a dozen or more functions.

In the old electronics dictionary:
ground = common reference point.

The "Planet Earth" is also a conductor.

I think you will find many, including myself, often misapply "bonding" and "grounding' If you properly address EGC vs GEC as you have and different between grounded and grounded you are ahead of the game (and avoid the term "ground").

Ungrounded and grounded

I think that should read groundED and groundING, the first usually carries current and the latter only during faults.

snipped/pasted from 2017 NEC art 100 definitions. The word ground on it's own has a definition, when used with other specific words within the NEC has a specific definition for that particular combination or phrase.
