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 non-current-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 whose function is to interrupt the electric circuit to the

load when a fault 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.

Health care facilities--Buildings or portions of buildings and mobile homes that contain, but are

not limited to, hospitals, nursing homes, extended care facilities, clinics, and medical and dental

offices, whether fixed or mobile.

Heating equipment--For the purposes of 1910.306(g), the term "heating equipment" includes

any equipment used for heating purposes if heat is generated by induction or dielectric

methods.

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

elevator or dumbwaiter is designed to operate.

Identified--Identified, as used in reference to a conductor or its terminal, means that such

conductor or terminal can be readily recognized as grounded.

Induction heating--Induction heating is the heating of a nominally conductive material due to

its own I 2 R losses when the material is placed in a varying electromagnetic field.

Insulated conductor--See "Conductor."

Interrupter switch--(Over 600 volts, nominal.) A switch capable of making, carrying, and

interrupting specified currents.

Irrigation machine--An irrigation machine is an electrically driven or controlled machine, with

one or more motors, not hand portable, and used primarily to transport and distribute water for

agricultural purposes.

Isolated--Not readily accessible to persons unless special means for access are used.

Isolated power system--A system comprising an isolating transformer or it equivalent, a line

isolation monitor, and its ungrounded circuit conductors.
