My last incarnation did not limit a short as being between 2 ungrounded conductors.......go back and look.The last incarnation of your proposal still stated that a short was only between two ungrounded conductors, I believe, which I still disagree with. If you were to create a definition and try to sell it to the CMP, then I would say:
I would say anything wrong other than that is a ground fault.Short Circuit: An intentional or unintentional low-impedance connection between two insulated conductors.
As far as your comments to the other rules where the terms short circuit and ground fault are equal.....I still firmly disagree. A Ground Fault by definition is a defined path. A Short Circuit by accepted definition has low impedance. A Ground Fault may or may not have low impedance, where a short circuit always does. Following the same logic, an Arc Fault is not a short circuit due to high impedance.Originally Posted by IBEW441DC
Short Circuit-An intentional or unintentional, low impedance conducting connection, between any ungrounded conductor(s) establishing a difference of potential, or between any ungrounded conductor(s) and a grounded conductor,or between any ungrounded conductor(s) and an equipment grounding conductor.
FPN (1): A Ground Fault is not a short circuit when subject to high impedance (see Article 250.2 Definitions).
FPN (2): An Arc Fault is not a short circuit due to high impedance.
FPN (3): A Short Circuit is not an intentional or unintentional electrical conducting connection between a grounded conductor and an equipment grounding conductor.(see 250.6 Objectionable Current) An example of objectionable current is neutral current flowing on paths other than permitted by the Code.
