T~ey should not occupy the same duet,manhole or handhole of con- duit systems with electric light or power wires. Single man holes separated into sections by means of parti- tions of brick, concrete or tile will be considered as Conforming. with the above rule. Paragraphs ~q~ to (w) inclusive do not apply when the entire circuit is run in underground conduit from the central station to the block in which the building is located,provided the circuit within the block is so placed as to be free from chance of acci- dental contact with electric light and power wires of OVer two hundred and fifty Volts. {q) When outside wires are run on sam~ ~pole with electric light or power wires, the distance between the two inside pins of each cross-arm must not be less than twenty-four{2~) inches. Signalling wires being smaller ~nd more liable to break ~nd fall, shou~ld generally be.pl~ced on the lower cross-arms. When wires are carried in cables,paragraphs {v},{s) and {w) do not apply. The e~bles may be of the metal sheath type with con- ductors insulated with paper or other suitable astoria!, or it may be of the non-metallic sheath type in which case the insula- tion on the individual conductors shall confrom to the require- monte of paragraph (s) except that the protective covering on in- dividual conductors may be omitted. ~ {r) The wires from the last outside supp6rt '4o the pro- tector and wires attached to the outside walls of buildings must have a rubber insulation not less than 1/~ of an inch in thick- ness and covered by a substantial braid, and on frame building or frame buildings or frame pewtions of other buildings shall, where not in condu/t, be supported on glass or porcelain insula- tors, or knobs. (S) Wires shall enter buildings either through non-eom- bustible, non-absorptive insulating bushings or through aPproved rigid conduits. The bushings shall slope upward from the outside, or where this cannot be done, the wires shall be provided with drip loops immediately outside the bushings. ~ore than one wire may enter through the same bushing if desired. The conduit shall be so placed as to prevent the entrance of moisture, and fitted ,with an approved bushing or service head. (t) Must be provided with an approved protective device located as near as possible to the entrance of wires to building. The protector must not be placed in the immediate vicinity of easily ignited ,stuff, or where exposed to inflammable gases or dust or flyings of combustible materials. lu) Wires from entrance to buildings to protector,must, where not in conduit, be supported in porcelain insulators so that they will come in 'contact with nothing except their designated supports. IV) If excessive induction is caused in other nearby wires, such other wires must be run in iron conduit or armored cable. ~wl In radio stations used for receiving only. the groun~ in~ ~w~ m~y be replaced by a ~imila~ly ~oun~e~ and grounded short gap 1/8 inch or less or vaccum type lightning arrestor.

In all cases,kin!~ coils and sharp ~r~d~ in the .wires between the arrestn~ outdoor lines must be avoided as far as possible. The ~witchboard does not ~necessarily ~fford thc only location meetin~ these r~- quirements. In fact, if the arrestors can be !oc~tod ir~ ~. safe accessible place away from the board, this should be done, for in case the s~rrestor should fail or be ~erious!y damaged, there ~ould then be less chance of starting arcs on the bo~rd.
