Definitions Applicable to 29 CFR 1926 Subpart K cont'd

DOE-HDBK-1092-2004

Feeder--All circuit conductors between the service equipment, or the generator switchboard of

an isolated plant, and the final branch--circuit overcurrent device.

Festoon lighting--A string of outdoor lights suspended between two points more than 15 feet

(4.57 m) apart.

Fitting--An accessory such as a locknut, bushing, or other part of a wiring system that is

intended primarily to perform a mechanical rather than an electrical function.

Fuse--(Over 600 volts, nominal.) An overcurrent protective device with a circuit opening fusible

part that is heated and severed by the passage of overcurrent through it. A fuse comprises all

the parts that form a unit capable of performing the prescribed functions. It may or may not be

the complete device necessary to connect it into an electrical circuit.

Ground--A conducting connection, whether intentional or accidental, between an electrical

circuit or equipment and the earth, or to some conducting body that serves in place of the earth.

Grounded--Connected to earth or to some conducting body that serves in place of the earth.

Grounded, effectively (Over 600 volts, nominal.)--Permanently connected to earth through a

ground connection of sufficiently low impedance and having sufficient ampacity that ground fault

current which may occur cannot build up to voltages dangerous to personnel.

Grounded conductor--A system or circuit conductor that is intentionally grounded.

Grounding conductor--A conductor used to connect equipment or the grounded circuit of a

wiring system to a grounding electrode or electrodes.

Grounding conductor, equipment--The conductor used to connect the noncurrent--carrying

metal parts of equipment, raceways, and other enclosures to the system grounded conductor

and/or the grounding electrode conductor at the service equipment or at the source of a

separately derived system.

Grounding electrode conductor--The conductor used to connect the grounding electrode to the

equipment grounding conductor and/or to the grounded conductor of the circuit at the service

equipment or at the source of a separately derived system.

Ground fault circuit interrupter--A device for the protection of personnel that functions to

deenergize a circuit or portion thereof within an established period of time when a current to

ground exceeds some predetermined value that is less than that required to operate the

overcurrent protective device of the supply circuit.

Guarded--Covered, shielded, fenced, enclosed, or otherwise protected by means of suitable

covers, casings, barriers, rails, screens, mats, or platforms to remove the likelihood of approach

to a point of danger or contact by persons or objects.

Hoistway--Any shaftway, hatchway, well hole, or other vertical opening or space in which an

elevator or dumbwaiter is designed to operate.

Identified (conductors or terminals)--Identified, as used in reference to a conductor or its

terminal, means that such conductor or terminal can be recognized as grounded.
