On 3 or 4 wire services an ap roved service switch with blades and fuses in the ungrounded conductors only, equipped with an approved strap to disconnect the neutral, will be allowed by this Department. {III 7, Where the load on 2 or more meters will cause an un- balanced condition on the service, the service conductors must be equal in size and of sufficient capacity to carry the larg- est of the two or more loads. S. all overhead services must be brought to either the extreme front or rear of a building. 9. This Department assumes full authority over all electrical installations within the property line. This refers especially to services regardless of whether they are overhead, under- ground from an underground source, or underground from an over- head source. The size of the services must comply v,Ath rules and regulations of this Department, within the building line. 10. The ungrounded legs of all underground services must be lead covered. The grounded leg need not be lead covered. (weatherproof or rubber covered). 11. ,here practicable, meters for private residences shall be installed in cabinets built into theeexterior wall and ac- cessible from the outside of the build.,'ng only. In this case the 2 foot minimum distance from meter to the permanent ground level may be reduced but the distance from the bottom of the cabinet to the permanent ground level shall not be less than eighteen inches. Section. U. OUTLETS AND BRANCH CIRCUITS. 1. In dwellings, flats, rooming houses and apartment houses, not more than 12 outlets and not more than 20 medium base lamp sockets shall be connected to any branch circuit supplying current for lighting, and no group of lamps or other devices requiring more than 1000 watts shall be connected to any such circuit. No special permission will be granted for lighting circuits of greater wattage. 2. The minimum total wattage, the minimum number of 1000 watts branch circuits required, and the distribution of outlets on the branch circuits, shall be determined by computing the various outlets as requiring not less than the following mini- mum wattages: (For certain exceptions, see sub -section, (2-a). Ceiling outlets, living rooms . . . 250 watts XIV Ceiling outlets, dining rooms . . . 250 watts Ceiling outlets, libraries . . . . 150 watts Ceiling outlets, parlors Ceiling outlets, dens . . . . . 250 watts . . . . . . 100 watts Ceiling outlets, breakfast rooms . 100 watts Ceiling outlets, breakfast nooks . 50 watts Ceiling outlets, kitchens with but I outlet in center, between kitchens and nooks . . . . . . . . . . . . 150 watts Ceiling outlets, kitchens . . . . . 100 watts Ceiling outlets, bedrooms . . . . . 100 watts In all other locations, 50 watts each. Above ceiling outlet ratings apply to the first ceiling outlet in the rooms specified. Extra or additional ceiling outlets in the same room may be rated at 50 watts each. In any room which is equipped with bracket outlets only, such out- lets shall be rated at and wired for a total wattage at least equal to that required by the above table for ceiling outlet in such room, but in no case for less than 50 watts per outlet. (For example, in a living room with no ceiling outlet, but j with two bracket outlets, the two bracket outlets must be rated at not less than 125 watts each.9 2-a-1. Exceptions to the above requirements are allowed as follows: 2-a-2. In three room apartments, one of the rooms used both as living room and bedroom, or both as dining room and bedroom, may be classed as a bedroom, and ceiling outlet in ors such room may be rated at a minimum of 100 watts. 2-a-3.
