The location of the outlets for the heating appliances is not of the least importance. For many purposes, the flush receptacle in the baseboard of the room answers many requirements. In other places, for instance, a receptacle placed beneath the bracket lamp in the bathroom upon the same circuit as the lamp, is very convenient as a connection for the electric shaving mug or the massage motor. Similarly, a suitable outlet placed near the head of the bed is most convenient for operating a heating pad as it does not necessitate unscrewing a lamp at night.
The house illustrated in figs. 1,006 to 1,008 is an example of the use of a single electric heating circuit with a restricted use of the lighting circuit for heating purposes.
[Illustration: FIG. 1,009.—Diagram illustrating wiring with combination of moulding, flexible tubing or conduit in non-fireproof building, where wiring had not been originally installed. In such cases the moulding may be run in a cornice in the hall. When objectionable to have the work exposed in the rooms, taps may be made in the moulding opposite each room and the circuit extensions from the moulding to the center outlets in the rooms may be run in flexible conduit, fishing the wires from the moulding to the ceiling outlet. The use of wooden moulding in new buildings is not to be recommended for the reason that it is not usually fireproof, and it would be better to run the conductors concealed in some form of conduit; if the circuit work were installed at the time the building is erected, it would cost but little more than moulding, and would be much more substantial. In some cases, however, wooden moulding might be provided in a new building on the ceiling as a means of affording facilities for making connections to outlets over desks, tables, etc., where it would be impossible to locate the outlet exactly before the building was plastered. In such cases, the moulding could be installed on the ceiling at a distance of 18 to 24 inches from the walls, forming a rectangle on the ceiling.]
[Illustration: FIG. 1,010.—Feeder system for large hotel. The cellar, basement, and ground floors are supplied by separate feeders, because of the importance of having continuous and uninterrupted lighting service at these floors. The three distributing centers at the cellar are supplied by a single feeder. Three of the eight distributing centers at the basement floor serve to supply the outside lights, as described above. The distributing center for the outside street lamps is supplied by a separate feeder from the main switchboard. Five of the distributing centers at the basement floor serve for the basement lights only; they are fed by two separate feeders, one of which serves two centers and the other three centers as shown. Each of the three centers at the ground floor is supplied by a separate feeder. The upper floors, from the first to the fourteenth inclusive, are divided into two symmetrical sections. Each section has its own distributing center, and its own set of supply feeders. The feeder terminates at the middle center of a group of three, and is extended by mains to the corresponding centers at the floors immediately above and below. Each feeder from the first to the twelfth floor inclusive serves to supply three distributing centers.]
