DOE-HDBK-1092-98

Grounding electrode resistance--The term means the resistance of the grounding electrode to earth.

Grounding electrode conductor (grounding conductor)--The term means a conductor used to

connect equipment or the grounded circuit of a wiring system to a grounding electrode.

Grounded conductor--The term means a system or circuit conductor which is intentionally

grounded.

Grounded system--The term means a system of conductors in which at least one conductor or point

(usually the middle wire, or neutral point of transformer or generator windings) is intentionally

grounded, either solidly or through a current-limiting device (not a current-interrupting device).

Hotline tools and ropes--The term means those tools and ropes which are especially designed for

work on energized high voltage lines and equipment. Insulated aerial equipment especially designed

for work on energized high voltage lines and equipment shall be considered hot line.

Insulated--The term means separated from other conducting surfaces by a dielectric substance

(including air space) offering a high resistance to the passage of current.

NOTE: When any object is said to be insulated, it is understood to be insulated in suitable manner

for the conditions to which it is subjected. Otherwise, it is within the purpose of this subpart,

uninsulated. Insulating covering of conductors is one means of making the conductor insulated.

Insulation (as applied to cable)--The term means that which is relied upon to insulate the conductor

from other conductors or conducting parts or from ground.

Insulation shielding--The term means an envelope which encloses the insulation of a cable and

provides an equipotential surface in contact with cable insulation.

Isolated--The term means an object that is not readily accessible to persons unless special means of

access are used.

Manhole--The term means a subsurface enclosure which personnel may enter and which is used for

the purpose of installing, operating, and maintaining equipment and/or cable.

Pulling tension--The term means the longitudinal force exerted on a cable during installation.

Qualified person--The term means a person who by reason of experience or training is familiar with

the operation to be performed and the hazards involved.

Switch--The term means a device for opening and closing or changing the connection of a circuit.

In these rules, a switch is understood to be manually operable, unless otherwise stated.

Tag--The term means a system or method of identifying circuits, systems or equipment for the

purpose of alerting persons that the circuit, system or equipment is being worked on.
