(a) The following wiring requirements shall serve as the minimum standard for electrical wiring systems in existing one, two and three-family residences. It shall be understood that this standard is to co-exist with the National Electrical Code, as adopted in Section 1406.01, but if any conflict, misunderstanding or disagreement results from such co- existence, the National Electrical Code shall control.
(1) Rewiring. Where a thirty-ampere, two-wire service exists in a residence, a 100-ampere service shall be installed to meet the minimum requirements of this section. If the existing service is sixty-ampere, three-wire, and is in good condition, the service does not necessarily have to be changed to 100-ampere service, provided the service satisfies the load.
(2) Installation method. All work shall be done in a neat and workmanlike manner.
(3) Outlets. As a general rule, each habitable room shall contain at least two wall-type convenience outlets located on opposite walls or as otherwise permitted by local inspection authority, but in no case shall more outlets than required by the National Electrical Code be required. Each living room shall have four duplex receptacles to supply appliances used therein unless a specific exemption is granted.
(4) New outlets. All new outlets installed on new wiring shall be of the grounded type.
(5) Existing outlets. Existing electrical outlets which are installed in a workmanlike manner, with approved materials, and with proper circuitry, need not be changed. Existing ungrounded outlets may be replaced with new ungrounded devices.
(6) Lighting. When ceiling lighting fixtures are replaced on original wiring, boxes or loompans shall be used. Existing or replacement nonmetallic bathroom and kitchen fixtures need not be grounded if connected to original wiring. Every water closet compartment, bathroom, laundry room and public stairway shall contain at least one supplied ceiling or wall-type electric lighting fixture.
(7) Kitchen circuits. All kitchens shall have at least three convenient outlets, one of which shall be on a twenty-ampere circuit. Any additional outlets shall be on twenty- ampere grounded circuits.
(8) Laundry circuits. When laundry facilities exist, a separate twenty-ampere grounded circuit shall be provided for laundry receptacle(s).
(9) Furnace circuit. A minimum fifteen-ampere separate circuit shall be provided for a heating system, when the system requires electric circuit. No other load shall be connected to this circuit. A heating system may include a furnace, humidifier and electronic filter.
(10) Knob and tube wiring. All original knob and tube branch circuit wiring shall be reconnected on fifteen-ampere circuits.
(11) Fuses. If Edison-base fuses are used they shall be type S.
(12) Out-buildings. Attached and unattached buildings, with wiring, on the same premises, shall meet the requirements of the local code.

(b) Except in one or two-family dwellings and rowhouses and apartment buildings separated from other dwelling units by a four-hour fire wall or separated by ten feet of yard space, from adjacent buildings or lot lines, the electrical wiring shall be in conduit or electrical metallic tubing (E.M.T.), except where it is impractical due to sharp turns and similar physical conditions, where flexible metal conduit may be used. Armored cable shall not be permitted for any type of electrical wiring.
Electrical wiring in the kitchen and bath area requires metal boxes for fixtures to be used in these locations.
