NATIONAL ELECTRIC CODE IN THE CAROLINAS

 

SOUTH CAROLINA

South Carolina adopted the 2002 NEC July 1, 2003.

The following is quoted in piecemeal: Every city and county in South Carolina that does not legally "opt out" of the Code Enforcement Program, must adopt and enforce the building codes required by law and authorized by the Building Codes Council. Local jurisdictions are restricted from promulgating their own building codes, in whole or in part, or adopting building codes not authorized by the Council. All chapters (except the Administrative Chapter) of all codes must be adopted in their entirety. Administrative Chapters may be adopted as part of the code or adopted by local ordinance at the option of the local jurisdictions. Appendixes are not automatically adopted with the text of the code and must be adopted separately, by name, in the adopting ordinance.

The 2002 edition of the NEC was adopted by local jurisdictions no later than July 1, 2003. Jurisdictions that have legally opted out of the code enforcement program at this time include: Richburg, Ehrhardt, Pamplico, Union County and Allendale County.

 

NORTH CAROLINA

North Carolina adopted the 2002 NEC in December 2001 for field practice and July 1, 2002 for testing.

KNOB AND TUBE WIRING

The oldest wiring system that may still be acceptable, and one still found fairly often in houses built before 1930, is "knob and tube." This system utilizes porcelain insulators (knobs) for running wires through unobstructed spaces, and porcelain tubes for running wires through building components such as studs and joists. Note whether knob and tube wiring splices are mechanically twisted, soldered, and taped, as required. Knob and tube wiring should be replaced during rehabilitation; but if it is properly installed, needs no modification, has adequate capacity, is properly grounded, has no failed insulation, and is otherwise in good condition, it can be an acceptable wiring system and is still legal in many localities.

Check with local building code officials. Also check the terms and conditions of the home insurance policy in force to see if knob and tube wiring is excluded. The greatest problem with such wiring is its insulation, which turns dry and brittle with age and often falls off on contact, leaving the wire exposed. Insulation that can be seen to have failed also will likely have failed where wiring is concealed. If any failed insulation is observed, the knob and tube wiring should be replaced.  National electrical code prohibits knob and tube wiring from being installed in areas where it is in contacts with insulation.  This is most commonly found in attics when unknowing homeowners want to improve the energy efficiency of their home and insulate the attic.

Aluminum Wiring

INFORMATION ON SINGLE STRAND ALUMINUM WIRING
 
"Aluminum wiring, used in some homes from the mid 1960's to the early 1970's, is a potental fire hazard. According to the U.S. Consumer Product Safety Commission, fires and even deaths have been reported to have been caused by this hazard. Problems due to expansion can cause overheating at connections between the wire and devices (switches and outlets) or at splices. CPSC research shows that "homes wired with aluminum wire manufactured before 1972 are 55 times more likely to have one or more connections reach "Fire Hazard Conditions" than are homes wired with copper. "Post 1972" aluminum wire is also a concern. Introduction of the aluminum wire "alloys" in 1972 time frame did not solve most of the connection failure problems. Aluminum wiring is still permitted and used for certain applications, including residential service entrance wiring and single-purpose higher amperage circuits such as 240V air conditioning or electric range circuits." - North Carolina Home Inspectors Licensure Board.

ZINSCO ELECTRICAL PANELS

Some common beliefs in the electrical community concerning Zinsco Panels are that the attachment spring was sometimes looser than it should have been for full contact; the aluminum bars changed physically to a less conductive and "coated" or oxidized state once overheated (or even heated); and the breaker style seemed to trap heat near the attachment screws or at the attachment clip, damaging nearby breakers as well as the overheating breaker.  These issues have resulted in what some people to believe is a higher than normal failure rate.  Zinsco panels are no longer manufactured.
