Pagina 53 - Must be so suspended that the entire weight of the socket and lamp will be borne by knots under the bushing in the socket, and above the point where the cord comes through the ceiling block or rosette, in order that the strain may be taken from the joints and binding screws.
Pagina 46 - In breweries, packinghouses, stables, dye-houses, paper and pulp mills, or other buildings specially liable to moisture or acid, or other fumes liable to injure the wires or insulation, except where used for pendants, conductors — a. Must be 'separated at least six inches.
Pagina 43 - Must be so placed in wet places that an air space will be left between conductors and pipes in crossing, and the former must be run in such a way that they cannot come in contact with the pipe accidentally. Wires should be run over all pipes upon which moisture is likely to gather, or which by leaking might cause trouble on a circuit.
Pagina 47 - ... the conductors, and the conductors then to be pushed or fished in.

Must not be so placed as to be subject to mechanical injury by saws, chisels or nails. e. Must not be supplied with a twin conductor, or two separate conductors, in a single tube.
Pagina 55 - Must each be heavily insulated with a coating of moisture-proof material from the point of entrance to the transformer, and, in addition, must be so covered and protected that mechanical injury to them, or contact with them, shall be practically impossible. b. Must each be furnished, if within a building, with a switch and a fusible cutout where the wires enter the building, or where they leave the main line, on the pole or in the conduit.

Pagina 51 - Supply conductors, and especially the splices to fixture wires, must be kept clear of the grounded part of gas pipes, and where shells are used, the latter must be constructed in a manner affording sufficient area to allow this requirement.
Pagina 44 - Must be so spliced or joined as to be both mechanically and electrically secure without solder. The joints must then be soldered, to insure preservation, and covered with an insulation equal to that on the conductors.
Pagina 43 - The insulating covering of the wire to be approved under this section must be solid, at least 3 -64th of an inch in thickness, and covered with a substantial braid. It must not readily carry fire, must show an insulating resistance of one megohm per mile after two weeks...
Pagina 44 - All joints must be soldered, even if made with some form of patent splicing device. This ruling applies to joints and splices in all classes of wiring covered by these rules.
