Week 3 Definitions Flashcards
Grounded (grounding)
Connected (connecting) to ground or to a conductive body that extends the ground connection
Bonded (Bonding)
Connected to establish electrical continuity and conductivity
Ground fault
An unintentional, electrically conductive connection between an ungrounded conductor of an electrical circuit and the normally non-current-carrying conductors, metal enclosures, metal raceways, metal equipment, or earth.
Effective ground-fault current path
An intentionally constructed, low-impedance electrically conductive path designed and intended to carry current during ground-fault events 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
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, grounded conductors, equipment, or the earth to the electrical supply source
Grounded conductor
A system or circuit conductor that is intentionally grounded
Grounding electrode
A conducting object through which a direct connection to earth is established
Grounding electrode conductor
A conductor used to connect the system grounded conductor or the equipment to a grounding electrode or to a point on the grounding electrode system
Equipment grounding conductor
A conductive path(s) that is part of an effective ground-fault current path and connects normally non-current-carrying metal parts of equipment together and to the system grounded conductor or to the grounding electrode conductor, or both.
Bonding jumper, equipment
The connection between two or more portions of the equipment grounding conductor
Main bonding jumper
The connection between the grounded circuit conductor and the equipment grounding conductor, or the supply-side bonding jumper, or both, at the service
System bonding jumper
The connection between the grounded circuit conductor and the supply-side bonding jumper, or the equipment grounding conductor, or both, at a separately derived system
Supply-Side bonding jumper
A conductor installed on the supply side of a service or within a service equipment enclosure(s), or for a separately derived system, that ensures the required electrical conductivity between metal parts required to be electrically connected.
Ground fault circuit interrupter
A device intended for the protection of personnel that functions to de-energize a circuit or portion thereof within an established period of time when a ground-fault current exceeds the values established for a Class A device.
Ground fault protection of equipment
A system intended to provide protection of equipment from damaging line-to-ground fault currents by operating to cause a disconnecting means to open all ungrounded conductors of the faulted circuit. The protection is provided at current levels less than those required to protect conductors from damage through the operation of a supply circuit overcurrent device.
