(b)
					 Conductors normally grounded for the protection of persons shall be arranged

					 used; or in lieu thereof other ducts, runways, or compartments of tile,
					 bitumenized fiber, concrete, or other suitable fire-resistive materials may be
					 used, if containing no exposed combustible material. In damp places, conduits,

(b)
Conductors above 750 volts in conduits or sheathing.
Conductors operating at over 750 volts unless separately supported and
					 effectively isolated by elevation or by enclosing in suitable compartments or

					 metal conduits or suitable fire-resistive ducts or compartments, with the metal
					 sheathing permanently grounded. Other covering may be used in suitable grounded
					 metal conduit or insulating duct, when installed in dry locations. The conduit
					 or duct shall provide a smooth runway with smooth outlets. Metal conduit, if
					 used, shall be made electrically and mechanically continuous with the metal
					 casings of conduit fittings.
(c)
Metal sheathed cable outlets above 750 units.
Insulation of
					 the several conductors of multiple conductor cable, where leaving the metal
					 sheath at outlets, shall be thoroughly protected from mechanical injury,
					 moisture and electrical strains by means of a pot head or equivalent
					 method.
(d)
Open conductors
					 above 750 volts.
When any open insulated conductor above 750 volts,
					 or any open bare conductor above 300 volts to ground, is necessarily brought
					 closer to the floor line than the clearances required for isolation by
					 elevation, they shall be guarded by permanent screens, by enclosing partitions,
					 or by suitable barrier guards.
(e)
					 If barrier rails only are used, the surrounding floors shall be provided with
					 suitable insulating platforms, mats, or covers. Reference should also be made
					 to §

					 more pieces of electrical supply equipment or supply lines are operated as a
					 single unit no switch is necessarily required between them.
(d) Switches are not required in underground
					 manholes or in transformer vaults except as may be deemed necessary by the

Current through Register Vol. 54, No. 28, July 13, 2024
(a)
Capacity.
Switches used
					 as other than disconnectors shall be of suitable voltage and ampere rating for
					 the circuit on which they are installed, and be marked with the current which
					 they are able to safely interrupt. Disconnectors shall be of suitable voltage
					 and ampere rating for the circuit on which they are installed, and shall be
					 marked with warning against opening when carrying load. Where a group of
					 disconnectors is contained in one room or compartment a single conspicuous sign
					 may be sufficient.
(b)
Locking.
Remotely controlled switches, oil switches and
					 disconnectors shall be arranged so that they may be secured or blocked in the
					 open position and plainly tagged to prevent careless closing while work is
					 being done on equipment controlled by them, unless the switches are so
					 constructed or installed as to prevent accidental closing or live or moving
					 parts of the equipment they control are so guarded as to render blocking and
					 tagging unnecessary. If the accidental opening of a switch or disconnector
					 might cause hazard, similar arrangements should be used for retaining them in
					 closed position. Locking should be used rather than blocking wherever parts of
					 equipment are remote from the point of control. Locking or securing doors of
					 compartments is a means of securing switches in the open position to prevent
					 careless closing while work is being done on the equipment controlled. Blocking
					 the jaws of knife switches is also a method.
(c)
Air brake.
Unless a
					 switch operating on a circuit above 750 volts makes an air break, there shall
					 be installed between it and the source of energy supply a suitable air or oil
					 break disconnector or equivalent device having an air or oil gap suitable for
					 the operating voltage of the circuit. Reference should also be made to §
											39.358 (relating to protecting
					 workmen by disconnectors).
(d)
Alignment.
Knife switches shall maintain such alignment under
					 service conditions that it may be possible to close them with a single
					 unhesitating motion.

(3) Electrical utilization equipment,
					 however, as well as generating equipment, if enclosed in a separate room which
					 is inaccesible to unauthorized persons, and when in service is under control of
					 a qualified electrical operator whose attention is not distracted by other
					 processes, shall be installed in conformity with the provisions of §§

(3) In certain instances if temporary
					 installations or installations are shortly to be discarded or
					 reconstructed.
(4) In cases of
					 emergency, or pending decision of the administrator, the person responsible for
					 the installation may decide as to modifications or waiver of any rule, subject

(a)
					 Electrical utilization equipment shall be of such construction and so installed
					 and maintained as to reduce the life hazard as far as practicable.
(b) The requirements of the National
					 Electrical (Fire) Code for the installation of wiring and fittings should be
					 followed.
(c) If materials or
					 devices are available which have been subjected to examination by some properly
					 qualified body and found to comply with the general requirements of the
					 National Electrical Safety Code, the National Electrical Code, and other
					 nonconflicting accepted standards which apply for any given purpose, such
					 materials or devices should be used in preference to others which have not been
					 so examined regarding their suitability for the given purpose. In order to
					 avoid the necessity for repetition of such examinations by different examiners,
					 frequently with inadequate facilities for such work, and to avoid the confusion
					 which may result from conflicting reports as to the suitability of devices
					 examined for a given purpose, it is necessary that such examinations be made
					 under standard conditions, and the record made generally available through
					 promulgation by organizations properly equipped and qualified for experimental
					 testing, inspections of the run of goods at factories and service value
					 determinations through field inspections, and whose findings are subject to
					 appeal to the Bureau of Standards.

					 circuits are not required to be grounded:
(1)
					 Circuits on two-wire, direct-current systems.
(2) Circuits entirely unexposed to leakage or
					 induction from higher voltage circuits, either through overhead construction or
					 through transformers or other devices. It is recommended, however, that all
					 three-wire, not delta three-phase, circuits, even if unexposed, have their
					 neutrals grounded; and that multiphase circuits, even if unexposed where partly
					 used for lighting, be so arranged and grounded that the lighting circuits have
					 the lowest practical voltage ground.
(3) Circuits over 150 volts to ground.
					 Reference should be made to §
												39.199 (relating to guarding or
					 isolating live parts).
(4) Electric
					 furnace and welding circuits. Reference should be made to §

Current through Register Vol. 54, No. 28, July 13, 2024
(a) In
					 locations where explosives, inflammable gas, or inflammable flyings normally
					 exist in dangerous quantities all parts at which sparking or arcing is liable
					 to occur shall be enclosed so as to reduce the hazard as far as
					 practicable.
(b) This protection
					 should be obtained by any one of the following methods:
(1) By placement in separate compartments or
					 rooms, free from explosives, inflammable gas, and inflammable vapors.
(2) By using casings of the inclosed type,
					 ventilated, if necessary, when dust or flyings are present.
(3) By using explosion-proof casings when
					 inflammable gases exist in dangerous quantities.
