(b) Three conductors having a current carrying capacity of 95 amperes for individual occupancy buildings having 1200 or less square feet of floor area and not more than 76 amperes connected load. (c) Three conductors having a current carrying capacity of 55 amperes for individual occupancy of buildings having 600 or less square feet of floor area and not more than k5 amperes connected load and for billboards with not more than 45 amperes total connected load. (d) Two conductors having a current carrying capacity of 55 amperes for buildings having 100 or less square feet of floor area and not more than two 20-ampere two-wire circuits and for billboards with not more than two 20-ampere two-wire circuits.

Also sub-section (f) of the above paragraph 16 is added as an exception to permit a more economical electrical installation in old residences that are being remodeled or repaired. SECTION III : Paragraph 83 is repealed and amended td permit the egditable use of aluminum conductors in electrical installations in place of capper con- ductors.

SECTION V: Paragraph (58) and (59) are repealed because the above paragraphs prohibited the use of certain types Electrical Metallic Tubing Couplings and Connectors, even though these fittings were approved for use, (in certain locations in buildings), by Underwriters Laboratories. The above fittings are widely used throughout the United States.
