locating these feeder shafts so that it is possible to carry the main conduits supplying the panels down to the basement and main source of supply. Very frequently the lobby and dining room ceilings are furred down for other purposes, which permits of carrying conduit to different shafts for this purpose. The number of panelboards on typical floors is dependent upon the size of the floor, but each floor should have at least one panel. These panels are usually of the knife switch pattern with cartridge fuses as they are not used for the control of lights. They should be locked and only accessible to the house electrician. Generally, panels
are placed from seventy-five to one hundred feet apart.
Separate lighting panels are installed for each store or similar rentable space and these are arranged for separate metering. It is customary to install a meter for each tenant in a hotel as very generally the cost of the electricity is not included in the rent and the tenant pays the customary rate for whatever current he consumes.
Separate power panels are generally provided for various groups of motors, such as elevators, fans, kitchen motors, laundry motors, etc. Feeders are carried to these panels and sub-feeders from the panel to each motor. These sub-feeders are controlled by switches and fuses on the panelboards and two main switches which should preferably be of the safety type are provided at each motor. These safety type switches are desirable because
in a hotel many of these switches are operated by an unintelligent class of help. A very desirable arrangement is to provide separate meters on these group panels as this enables the owner to determine the cost of current required for operating the variout departments which, in hotels, are frequently operated on a separate basis and the meter readings are a great aid for the bookkeeper in the distribution of his costs.
The sizes of feeders for the various panels are, of course, dependent upon the. size of the panels. On typical floors it is very general practice to include from three to five panels on one vertical
feeder. Thus if it was determined that three panels should be on one feeder the panels on the first three floors would be supplied by one feeder, those on the next three floors by another and so on.
A very desirable arrangement is to have the corridor lights on the guest room floors on alternate cicuits so as to obtain half or full illumination as may be required. It is also desirable to have the control of these lights, under the supervision of the room clerks. This is obtained by having the circuits supplying the corridor lights independent of the main bus-bars of the guest room floor panel on which they occtir. These circuits will then be supplied by two sub-feeders from the lobby panel, each sub-feeder supplying half of the corridor circuits. Local wall switches should also be used on each floor. In arranging the alternate circuits in the corridors care should be used to insure that
