At present the best AERIAL CABLE CONSTRUCTION. 833 practice after terminating the cable by any of the methods described,is to run a No. 18 B. & S. rubber-covered braided wire from theterminal in the cable box to the distributing insulator on the samepole, and then drop off from its insulator with the drop wire to thesubscribers premises. Drop wires differ largely, both bare and in-sulating wire being used. Drop wire should be No. 14 hard drawn. FIG. 612.—TEN-PAIR TERMINAL DISTRIBUTING TO RESIDENCES. copper if bare. If both are insulated, they should be not smallerthan No. 16 rubber-covered and braided, unless they are twisted, inwhich case they may be as small as No. 18. Frequently one bareand one insulated wire is used, these being run separate in practi-cally the same manner as two bare would be run. In this caseboth wires should be of No. 14 hard drawn copper.
