It also admits of alterationsbeing made quickly. The system of distribution is similar to the ordi-nary methods of wiring. A recess in the wallshould be provided for the reception of the mainand feeder line conduits exclusively, provided witha detachable cover throughout; or at a certainpoint on each of the different flows, exactly asshown in Fig. 2. In the figure showing tubes in recess A repre- HOW TO WIEE BUHDINGS. 39.

Usually the main wires are large,which make it advisable to have the cover of therecess detachable the whole length. The mainwires can be so arranged that a pair are run fromthe dynamo switchboard direct to each floor, orthe system of distribution can be so arrangedthat the wires can be looped in the conduit, fromfloor to floor, thus relieving the conduit of thestrain due to the weight of heavy conduct-ors. The connections can be made as shown inFig. 3. In Fig. 3, A represents main floor boxes, oneon each floor, to which are connected the con-duits for the main wires. The wires as seen arecut at each floor, so that instead of startingat A^ and drawing the wires through theconduit to A^, it is only drawn from
