Current through Register Vol. 54, No. 28, July 13, 2024
(a) All high
					 voltage wires installed underground shall be in the form of insulated
					 lead-covered cables, which shall be armored or effectively protected against
					 abrasion. The armor shall be electrically continuous throughout and shall be
					 effectively grounded. The installation of efficiently insulated wires in metal
					 conduit to transmit power underground shall be sufficient to meet this
					 requirement.
(b) All underground
					 cables and wires, unless provided with grounded metallic covering, shall be
					 supported by efficient insulators. The conductors connecting lamps to the power
					 supply shall in all cases be insulated.
(c) Cables and wires not provided with
					 metallic coverings shall not be fixed to walls or timbers by means of
					 uninsulated fastenings.
(d)
					 Overhead transmission lines between the generating station or substations and
					 the tunnel entrance shall be supported upon insulators, which shall be adequate
					 in quality, size, and design for the voltage transmitted. If the line is more
					 than 500 feet in length, lightning arresters shall be installed. The line,
					 except in the case of trolley wires, shall be maintained at least 10 feet above
					 the ground at the lowest point, except at the point of entrance to the
					 tunnel.
(e) Buried cables shall be
					 continuously insulated and protected by a metallic sheath, preferably lead. If
					 they are so located that there is a possibility of danger to the sheath by
					 puncturing, the cables shall be further protected by armor.
(f) When the exposed ends of cables enter any
					 fittings, they shall be so protected and finished off that moisture cannot
					 enter the cable or the insulating material leak out, if of an oily or viscous
					 nature.
(g) When unarmored cables
					 or wires pass through metal frames or into boxes or motor casings, the holes
					 shall be substantially lined with insulated bushings.

(a) Any
					 completely insulated feeder circuit in excess of 24-kilowatt-capacity leading
					 underground, if the potential does not exceed the limits of a medium voltage
					 potential, shall be provided above ground with a switch and an automatic
					 overload circuit breaker. In the case of ground return direct current circuits,
					 a switch and circuit breaker shall be installed in the underground side of the
					 circuit but may be omitted from the return side. Fuses may be substituted for

(c) Any branch shall be provided with a
					 switch of ample carrying capacity on each phase within 50 feet of the point
					 where it leaves the main circuit.
(d) Wires for all lighting circuits shall be
					 covered with an insulation adequate for the voltage of the circuit. Unless
					 encased in pipes or other metallic covering, wires shall be strung on porcelain
					 or glass insulators. Separate encased wires shall be kept at least three inches
					 apart except where they enter the fittings. Metallic casings, if used, shall be
					 efficiently grounded.

Current through Register Vol. 54, No. 28, July 13, 2024
(a) Trolley
					 wires shall be installed as far on one side of the tunnel as is practicable and
					 shall be securely supported and the supports insulated.
(b) Suitable protection shall be provided at
					 all places where men are required to work or pass under trolley or other bare
					 power wires which are placed less than eight feet above top of rail. This may
					 consist of channeling the roof or of placing boards along the wire, which shall
					 extend at least three inches below it, or in the use of any other device that
					 will afford ample protection. At all points where timbers or tools have to be
					 unloaded or transferred up a raise, the trolley wires shall be boxed or
					 otherwise protected as provided for in this section. All places where it is
					 required that the trolley wires shall be boxed, shall be well lighted with
					 electric lamps.

Current through Register Vol. 54, No. 28, July 13, 2024
(a) In all
					 shafts where the angle of inclination is above 45° from the horizontal, and
					 in all hoisting shafts or manway compartments, all power wires and cables shall
					 be amply protected by insulation and substantially fixed in position. All shaft
					 cable shall be supported on insulators that do not cause abrasion of the
					 covering or insulation, and shall be spaced so that no part of the cable is
					 under a tension greater than 1/4 its ultimate strength. The cable shall be held
					 in position at points between the insulators by grips or cleats that do not
					 cause abrasion of the covering or insulation. If the cables are not completely
					 boxed in and protected from falling material, space shall be left between them
					 and the side of the shaft so that they may yield and lessen a blow from falling
					 material. This requirement shall not be construed to prevent the installation
					 of efficiently insulated wires in metal conduit, to transmit power
					 underground.
(b) If it is not
					 possible to keep the cables or feed wires in tunnels at least 12 inches from
					 any part of the tunnel, car or locomotive, they shall be specially protected by
					 proper guards.

Current through Register Vol. 54, No. 28, July 13, 2024
(a) A good and
					 sufficient compressor plant for the compression of air shall be provided to
					 meet not only ordinary conditions, but emergencies, and to provide margin for
					 repairs at all times. Provision shall be made for storing in tanks at each
					 boiler house enough feed water to last 12 hours, unless connection is made with
					 two independent and separately sufficient sources of supply.
(b) The plant shall be capable of furnishing
					 to each working chamber a sufficient air supply for all pressure to enable work
					 to be done as nearly as possible in the dry.
(c) When electric power is used for running
					 compressors supplying air for compressed air tunnel work, there shall be
					 compliance with the following:
(1) There shall
					 be two or more sources of power from the power stations to the compressor
					 plant. The power feeders shall each have a capacity large enough to carry the
					 entire compressor plant load and normal overload. The feeders should preferably
					 run from separate generating plants of substations and be carried to the
					 compressor plant over separate routes and not through the same duct lines and
					 manholes, so that the breakdown of one feeder should not cause an interruption
					 on the other feeder.
(2) There
					 shall be duplicate feeder bus bars, and feeder connections to the bus bars
					 shall be so that either feeder can feed to each separate bus-bar set,
					 individually, or simultaneously to both sets.
(3) There shall be at least two compressors
					 so connected to the bus bars that they may be operated from either set of
					 busses. The compressors shall be fed from different bus bar sets, that a
					 breakdown of a feeder or bus bar would interrupt the operation of only part of
					 the compressor plant.
(4) Duplicate
					 air feed pipes shall be provided from the compressor plant to a point beyond
					 the lock.
