(A) Additions or extensions to, and altera- tions and renewals of existing installations shall be made in com- pliance with the provisions of this ordinance. In locations where metal covered electrical wiring is required, but the existing in- stallation was of some other approved type of wiring, the original type of installation may be used on work representing less than 50% of a circuit or circuits. Complete or approximately complete circuits shall be of the type required by this ordinance. If electrical system is altered or added to, existing open fuse blocks must be removed and replaced with a panel. OUTSIDE WORK SECTION 16. (A) No open wiring requiring more than one set of knobs or insulators to each service shall be installed on outside of building except as permitted elsewhere herein. Knobs or insulators shall be of the solid type, and nails or spikes shall not be considered as adequate suppm t for such knobs or insulators. SERVICES SECTION 17. (A) Two and Three -wire Services. All sing- le -phase lighting loads of less than 3300 watts or with not more - 13 - than two circuits may be served by two wires. Greater loads than 3300 watts shall be served by three wires. Thirty- ampere switches shall not be used for a three -wire service supplying more than four branch circuits. Where an installation has been wired and arranged for three -wire service, no two -wire energy supply or two -wire ser- vice shall be connected thereto without the written approval ob- tained in advance from the Chief Electrical Inspector. No service shall be smaller than No. 8 A.W.G. wire and one and one - quarter inch (1 -1 /4n) service pipe, except temporary services for con- struction, signboards and buildings under 400 square feet. (B) Space must be provided at the distribution center for protective equipment at least equal to the space required for a one hundred ampere (100 Amp.) panel or service switch. (C) Dwellings. Service heads for dwellings need not be lo- sated on the wall nearest the pole from which service drops are to be run, but shall be so located that the service drop may be in- stalled with only one point of attachment without crossing over adjacent premises.

Underground services may be installed in rigid non - metallic conduit, or armored cable approved for un- derground installations may be used. (E) Conductors in Rigid Metal Raceways. No other conduc- tors shall be placed in the service raceway, box, or other fitting with the service wires unless separated therefrom by an approved and permanent means forming a permanent compartment. This shall - 14 - not apply to the service switch box or to the grounding conductor. (F) Outdoor Installations. Switches, panelboards, etc., in- stalled outdoors shall be of a type approved for outdoor installa- tion. (G) OMMISSION OF MAIN SWITCH. Dwellings and apartment houses having from one to, but not exceeding, six subdivisions of load may be served by one set of service conductors without a master service switch; provided that the voltage to ground does not ex- ceed 150 volts, and that all subdivisions of load are protected by non - tamperable circuit breakers, installed in a single dead front cabinet, or in separate enclosure, or by switches with approved non - tamperable fuses. Such equipment shall be grouped at the near- est readily accessible point to where the service conductors enter the building. The top of such cabinet shall be not more than six feet six inches (616 ") above the floor. This exception does not , Ipply when there are subdivisions of service. (Note: Install meters and metering equipment as required by the serving utility.) VOLTAGE DROP SECTION 1$.
