#6. What is an intentionally constructed, low-impedance electrically conductive path designed and intended to carry current under ground-fault conditions?
CORRECT ANSWER INFO:
Correct answer is A: Effective Ground-Fault Current Path
NEC DEFINITION:
Effective Ground-Fault Current Path: An intentionally constructed, low-impedance electrically conductive path designed and intended to carry current under ground-fault conditions from the point of a ground fault on a wiring system to the electrical supply source and that facilitates the operation of the overcurrent protective device or ground-fault detectors.
(Article 100 Definitions: Part I General)
#7. What is an electrically conductive path from the point of a ground fault on a wiring system through normally non-current-carrying conductors, equipment, or the earth to the electrical supply source?
CORRECT ANSWER INFO:
Correct answer is B: Ground-fault current path
NEC DEFINITION:
Ground-Fault Current Path: An electrically conductive path from the point of a ground fault on a wiring system through normally non-current-carrying conductors, equipment, or the earth to the electrical supply source.
Informational Note: Examples of ground-fault current paths are any combination of equipment grounding conductors, metallic raceways, metallic cable sheaths, electrical equipment, and any other electrically conductive material such as metal, water, and gas piping; steel framing members; stucco mesh; metal ducting; reinforcing steel; shields of communications cables; and the earth itself.
