SECTION 8307. Existinq Buildinqs. Article 93 is hereby added to read as follows: ARTICLE 93 - APPLICATION TO EXISTING BUILDINGS 93-1. Alterations, additions, or renewal of existing wiring installations shall be made in compliance with the provisions of this code. EXCEPTION: When a renewal due to deterioration or damage does not exceed 50% of the electrical instal- lation in an existing building or structure, such renewal may be installed in the same manner as the existing installation. 93-2. When any building or structure, or portion thereof, is placed in a different occupancy classification those portions directly affected by such occupancy change shall be wired in compliance with the provisions of this Code. 93-3. Relocated buildings. Relocated buildings shall conform to the minimum standards as required in this Code for new buildings. EXCEPTION: Group H and I Occupancies excepted from require- ments herein subject to approval of Building Official. SECTION 8308. Sranch Circuits. Section 210Tl is hereby amended to,ad as follows: 210-1. Scope. The provi~Ons of this Article shall apply to branch circuits supplying lighting or appliance loads or combinations of such loads. Where motors or motor-operated appliances are connected to any circuit supplying lighting or other appliance loads, the provisions of both this Article and Article 430 shall apply. Article 430 shall apply where branch circuit supplies only motor loads. (a) Accessory or other buildings separately located on the same lot or premises shall have connecting conductors run underground. EXCEPTION: Overhead (12' high) may be used when horizontal run is in excess of 50 feet. (b) Where spare circuit protective devices are provided or space for future circuit protective devices are provided on the buss in any flush mounted panel, then raceways of sufficient capacity to permit utilization of such spares or spaces shall be provided to an accessible location. SECTION 8309. Branch Circuits. Section 210-21(b) is hereby amended to read as follows: (b) Receptacles. Receptacles installed on 20 ampere branch- circuits shall be of the grounding type and they shall be in- stalled in accordance with Section 210r7. The installation of grounding type outlets shall not be used as a requirement that all portable equipment be of the grounding type. See Article 250 for requirements for the grounding of portables. When connected to circuits having two or more outlets, receptacles shall conform to the following: 20-amp circuits ........ 15 or 20 amp rating 30-amp circuits .............. 30 amp rating 50-amp circuits .............. 50 amp rating Receptacles connected to circuits having different voltages, frequencies or types of current (AC or DC) on the same premises shall be of such design that attachment plugs used on such circuits are not interchangeable. Grounding receptacles rated at 15 or 20 amperes and installed in circuits of less than 150 volts between conductors shall be approved for use only on potentials less than 150 volts. Grounding receptacles rated at 15 amperes and installed in circuits of 151 to 300 volts between conductors shall be approved for use only on potentials not less than 151 volts. Receptacles rated at 15 amperes connected to 20 ampere branch circuits serving two or more outlets shall not supply a total load in excess of 12 amperes for portable appliances. Receptacles rated at 20 amperes connected to 20 ampere branch circuits serving two or more outlets shall not supply a total load in excess of 16 amperes for portable appliances. -15-
