Current through all regulations passed and filed through July 1, 2024
(A) Reserved.
(B) Definitions.
(1) "Circuit" means a conductor or system of
			 conductors through which an electric current is intended to flow.
(2) "Conductor" means a metallic material,
			 usually in the form of a wire or cable, suitable for carrying an electric
			 current. Does not include bus bars.
(3) "Current-carrying" means a conducting
			 part intended to be connected in an electric circuit to a source of voltage.
			 Noncurrent-carrying parts are those not intended to be connected.
(4) "De-energized" means being free from any
			 electrical connection to a source of a potential different from that of the
			 earth.
(5) "Energized" means
			 anything connected to an electrical source having a greater potential than that
			 of the earth.
(6) "Ground
			 connection" means the equipment used in establishing a path between an electric
			 circuit or equipment and earth. A ground connection consists of a ground
			 conductor, a ground electrode and the earth which surrounds the electrode.
(7) "Grounded" means connected to
			 earth or to some extended conducting body which serves instead of the earth
			 whether the connection is intentional or accidental.
(8) "Grounded effectively" means permanently
			 connected to earth through a ground connection or connections of sufficiently
			 low impedance and having sufficient current-carrying capacity to prevent the
			 building up of voltages which may result in undue hazard to connected equipment
			 or to employees.
(9) "Grounding
			 conductor" means a conductor which is used to connect the equipment or the
			 wiring system with a grounding electrode or electrodes.
(10) "Insulated" means separated from other
			 conducting surfaces by a dielectric substance or air space permanently offering
			 a high resistance to the passage of current and to disruptive discharge through
			 the substance or space. (Note: When any object is said to be insulated it is
			 understood to be insulated in a suitable manner for the conditions to which it
			 is subjected. Otherwise it is, within the purpose of this rule, uninsulated).
(11) "Insulating" (where applied
			 to the covering of a conductor or to clothing, guards, rods, and other safety
			 devices) means that a device, when interposed between an employee and
			 current-carrying parts, protects the employee making use of it against electric
			 shock, form the current-carrying parts with which the device is intended to be
			 used; the opposite ofconducting.
(12) "Phase" means one energized conductor of
			 an electrical system.
(13)
			 "Switch" means a device for opening and closing or for changing the connection
			 of a circuit. In this rule, a switch will always be understood to be manually
			 operated, unless otherwise stated.
(14) "Voltage (of a circuit)" means the
			 greatest root-mean-square (effective) difference of potential between any two
			 conductors of the circuit concerned. On various systems such as three-phase
			 four-wire, single-phase three-wire and three-wire direct current, there may be
			 various circuits of various voltages.
(15) "Voltage to ground" means, in grounded
			 circuits, the voltage between the given conductor and that point or conductor
			 of the circuit which is grounded; in grounded circuits, the greatest voltage
			 between the given conductor and any other conductor ofthe circuit.
(16) "Voltage" (or "volts") means the highest
			 effect electrical potential between any two conductors of the circuit concerned
			 except where, in certain paragraphs of this rule, reference is made to the term
			 "voltage (or volts) to ground".
