The wires brought out from the conduit system are 2. 5 inches apart, and thus a neat and safe job is secured. Fig. 120 shows a good elbow fitting, serving also as a pull-box, which is especially useful for wiring on wooden columns or making complicated turns, since it does away with awkward elbow work. For wiring outlets in groups on outdoor awnings, a receptacle like that shown in Fig. 121 answers very well. It is advisable to make up these outdoor circuits in the shop so that all that remains for the wiremen to do is to screw the Fig. 121. --Receptacle for outdoor work. Fig. 122. --Ground clamp. pipes in place. A good feature of this line of fittings is that they make good electrical contact with the conduit. Such is not the case with the ordinary outlet boxes, and since all conduit systems are required to be grounded, this is important. Fig. 122 shows a type of ground clamp applicable for conduit work. The conduit should be scraped clean before the clamp is applied. Another clamp of this description should be fastened to a water main and the two joined together with a copper wire sweated in the lugs. For terminating a conduit line outside a building, a fitting designed to prevent the ingress of moisture should be used. Fig. 123 illustrates a good device for this purpose, one advantage of which is that the porcelain cover spreads the wires the proper distance apart. Where conduit terminates in a switch or panelbox, the lining or casing of the panels must be of iron, and the conduits should be securely fastened to it so as to make a good electrical contact. . . .
