The following wiring requirements shall serve as minimum standards for electrical wiring systems for existing one, two and three-family dwellings in the City when an inspection is requested or wiring is to be done. These standards shall coexist with the National Electrical Code insofar as wiring methods are concerned, and conflicts, misunderstandings and disagreements that result from this coexistence shall be resolved as provided in Section 1408.05(b).
Where a 60-ampere service or less exists in a residence, a minimum 100-ampere (3-wire single phase) service with a main breaker and sixteen circuit capacity panel shall be installed.
All work shall be done in a neat and workmanlike manner.
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 the local inspection authority, but in no case shall more outlets than the number 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.
Existing bathrooms shall have at least one GFCI-controlled receptacle.
All new outlets installed on new wiring shall be of the grounded type.
Existing electrical outlets which were installed in a workmanlike manner, with approved materials and proper circuitry, need not be changed. Existing ungrounded outlets may be replaced with new ungrounded devices. All existing outlets in unfinished basements, as defined in NEC 210-8(a)(5), outdoors, and in outbuildings, shall have ground fault circuit protection.
All kitchens shall have at least three grounding-type duplex receptacles, on no less than two 20-ampere circuits. One circuit shall supply power for at least one countertop receptacle. Fixed appliances shall be circuited accordingly, and properly grounded. All new or existing receptacles within six feet of the kitchen sink shall be GFCI protected. All other new receptacles shall comply with section (d) above.
All single-family residences shall have a separate 20-ampere ground circuit for a laundry receptacle, where laundry facilities exist.
A minimum of one 15-ampere separate circuit shall be provided for the heating system, when the system requires an electric circuit. No other load shall be connected to this circuit. The heating system may include a furnace, humidifier and electronic filter.
KNOB AND TUBE WIRING
All original knob and tube branch circuit wiring shall be reconnected on 15-ampere circuits, and any tampered wire shall have its original insulation quality replaced. All exposed knob and tube wiring in basements shall be removed to the point where it is connected to refeed risers.
If Edison Base fuse holders are used, they shall be fitted with type “S” fuse adapters and fuse stats.
Attached and unattached buildings (with wiring) on the same premises shall meet the requirements of the local code. If the building is unattached and the wrong wiring is inoperative, the wiring shall be removed.
Smoke detectors must be installed according to the local code.
RANGES, DRYERS AND ALL OTHER 120/240 VOLT APPLIANCES
All existing or refed units must comply with Section 250-140 of the 1999 edition of the National Electrical Code. All new installations of such units shall comply with Sections 250-134 and 250-138 of such Code.
