A.    Communication cables and conductors for public use shall not occupy the same conduit duct, manhole, or other underground splicing chamber with supply cables or conductors unless separated from the supply cables or conductors by a partition constructed of brick, concrete, tile or other suitable material. When such a partition is installed, separate access to each compartment shall be provided by means of divided covers or equivalent construction. (See Appendix 8, Fig. 9 and 10)

This rule does not apply to utility tunnels, subways, or permanent cable trenches provided that supply cables and conductors of over 750 volts are either enclosed, guarded, installed in grounded metallic conduit, or have continuous grounded metallic sheath. Grounded metallic cable sheaths of the supply and communication systems need not be bonded. The cables and conductors of the supply and communication systems must be separately supported.

B.    Communication cables and conductors for public use shall not occupy the same manhole or other underground splicing chamber with supply cables or conductors, unless separated from the supply cables or conductors by a partition constructed of brick, concrete, tile or other suitable material. When such a partition is installed, separate access to each compartment shall be provided by means of divided covers or equivalent construction. (See Appendix B, Figure 10 ).

Exceptions:

(1)    Rule 44.1-B does not apply to utility tunnels, subways or permanent cable trenches provided that supply cables and conductors of over 750 volts are either enclosed, guarded, installed in grounded metallic conduit, or have a continuous grounded metallic sheath. Grounded metallic cable sheaths of supply and communication systems need not be bonded. The cables and conductors of the supply and communications systems must be separately supported. (See Appendix B, Figure 8. )

(2)    Rules 44.1-A and 44.1-B do not apply to communications systems either owned, operated or maintained by a supply utility.

(3)    Rule 44.1-B does not apply to mechanically and electrically protected (see Rule 22.9 ) communication systems.

(4)    Rule 44.1-A does not apply to dielectric communication cables either owned, operated or maintained a supply utility.

C.    Any work performed in substructures that contain energized electrical facilities will be performed by qualified personnel under the supervision of a qualified electrical worker.

A.    Communication cables and conductors for public use shall not occupy the same conduit with supply cables or conductors unless.

B.    Communication cables and conductors for public use shall not occupy the same manhole or other underground splicing chamber with supply cables or conductors, unless separated from the supply cables or conductors by a partition constructed of brick, concrete, tile or other suitable material. When such a partition is installed, separate access to each compartment shall be provided by means of divided covers or equivalent construction. (See Appendix B, Figure 10 ).
