GS153A-357 - PermitsNo person may commence or proceed with:
4. The installation, extension, alteration, or general repair of any electrical wiring, devices, appliances, or equipment except that in any one- or two-family dwelling unit a permit shall not be required for repair or replacement of electrical lighting fixtures or devices, such as receptacles and lighting switches, or for the connection of an existing branch circuit to an electric water heater that is being replaced, provided that all of the following requirements are met:
a. With respect to electric water heaters, the replacement water heater is placed in the same location and is of the same or less capacity and electrical rating as the original.
b. With respect to electrical lighting fixtures and devices, the replacement is with a fixture or device having the same voltage and the same or less amperage.
c. The work is performed by a person licensed under G.S. 87-43.
d. The repair or replacement installation meets the current edition of the State Building Code, including the State Electrical Code.
However, a permit is not required for the installation, maintenance, or replacement of any load control device or equipment by an electric power supplier, as defined in G.S. 62-133.8, or an electrical contractor contracted by the electric power supplier, so long as the work is subject to supervision by an electrical contractor licensed under Article 4 of Chapter 87 of the General Statutes. The electric power supplier shall provide such installation, maintenance, or replacement in accordance with (i) an activity or program ordered, authorized, or approved by the North Carolina Utilities Commission pursuant to G.S. 62-133.8 or G.S. 62-133.9 or (ii) a similar program undertaken by a municipal electric service provider, whether the installation, modification, or replacement is made before or after the point of delivery of electric service to the customer. The exemption under this subdivision applies to all existing installations.

Electrical Contractor Licensing Requirements
N.C. General Statute 87-43 defines electrical contracting as engaging or offering to engage in the business of installing, maintaining, altering or repairing any electrical work, wiring, devices, appliances or equipment.
Below are the license requirements and license exemption rules directly from the N.C. Board of Examiners of Electrical Contractors at
License Classification and Scope
There are 10 different classifications of electrical contracting licenses. Each license has a specific scope and limitation of work allowed. The Limited (L), Intermediate (I), and Unlimited (U) classifications allow a licensee to perform residential, commercial and industrial work. The Residential dwelling license (SP-SFD) permits electrical contracting projects pertaining to single-family detached residential dwellings. There are also six special restricted electrical contracting classifications that allow only a limited phase of electrical contracting work:
Low-voltage (SP-LV), Elevator (SP-EL), Plumbing, Heating, and Air Conditioning (SP-PH), Groundwater pump (SP-WP), Electric Sign (SP-ES), Swimming Pool (SP-SP).The scope for each of the special restricted classifications is listed in Section .0800 of the rules and regulations..0804. SCOPE OF SP-LV LICENSE(a) Definition. Low-voltage wiring is defined as:(1) wiring systems of 50 volts or less and control circuits directly associated therewith;
(2) wiring systems that have a voltage in excess of 50 volts and consist solely of power limited circuits meeting the definition of a Class II or Class III wiring system in the National Electrical Code; or(3) line voltage wiring that has a voltage no in excess of 300 volts to ground and is installed from the load-side terminals of a disconnecting means or from a junction box, either of which has been installed by others, for the specific purpose of supplying the low-voltage wiring system involved. Some low-voltage wiring systems that meet this definition are exempt under Rule .0805.(b) Scope. A special restricted low-voltage electrical contracting license authorizes the licensee to install, maintain, or repair only low-voltage wiring and directly related wiring. Wiring is directly related if it:(1) originates at the load-side terminals of a disconnecting means or junction box that:(a) has been installed, complete with line-side connections, by others for the specific purpose of supplying the low-voltage wiring system involved; and(b) is permanently and legibly marked to identify the low-voltage wiring system supplied; and(2) is not installed in a location considered as hazardous under the National Electrical Code.Statutory Authority G.S. 87-42; 87-43.3;Eff. October 1, 1988.Some low-voltage systems are exempt from the requirement of installation by a licensed electrical contractor.
Although a license may not be required, permits and inspections are still required.0805. EXEMPTION OF CERTAIN LOW-VOLTAGE WIRING SYSTEMS(a)
Exemption. The installation, maintenance or repair of certain low-voltage wiring systems may be performed by those not licensed by the Board if all of the following conditions are met:(1) the system is not required by the N.C. State Building Code;(2) the low-voltage control circuit and power supply is a Class II or Class III system as defined in the National Electrical Code;(3) the system operates at a voltage not in excess of 50 volts or meets the provisions for sound-recording and similar equipment in the National Electrical Code;(4) no part of the system is installed in an area considered as hazardous under the National Electrical Code;(5) the system is limited or protected by a circuit breaker, fuse or other current limiting device; and(6) a failure in the system would not, in the opinion of the electrical inspector having jurisdiction, create a shock or fire hazard to persons or property.(b)
Rulings. The Board's executive director shall research the requirements of the N. C. State Building Code, make field investigations of low-voltage wiring systems in question, and issue rulings on whether a low-voltage system meets the above criteria. When the executive director is unable to make a determination, he shall refer the case involved to the Board for a ruling.Statutory Authority G.S. 87-42; 87-43.3;Eff. October 1, 1988
