The NEC as adopted in Arkansas and state amendments

In April 2026 Dale drove to North Little Rock to sit in on the board's public hearing on the new electrical code. He was not there to speak; he wanted to hear what the inspectors and the other contractors said about kitchen islands and ground-fault protection, because those two topics had caused more callbacks at Ouachita Bend than anything else in the last code cycle. When he came back, he gathered the foremen in the shop. "The state is moving to the 2026 code with its own amendments," he said. "Some of them change what we price into every house. Tanisha, you are studying one edition for the exam and you will be installing under another. Learn both, and learn where Arkansas changes the book."

This lesson explains how Arkansas adopts the National Electrical Code, which edition applies, how the board amends it, how the amendments differ from the model code, how local governments fit in and how the exam edition relates to the job edition. It summarizes the board's rules in 17 CAR 210-401 and the 2026 rulemaking. It does not reproduce code text. Use your own copy of the NEC and the current rule for the exact requirements.

One code statewide

Arkansas adopts the NEC statewide by rule of the Board of Electrical Examiners. That is different from states where each city chooses its own edition. The board's rule names the edition of NFPA 70 that applies across the state, lists the Arkansas amendments and adds a workmanship standard. Under the 2026 rule, the adopted code is the 2026 edition of NFPA 70, the National Electrical Code, with Arkansas amendments, and the board also names ANSI/NECA 1, the standard for good workmanship in electrical construction, in its 2023 edition, as a guide for neat and workmanlike installation.

The rule also controls how the state moves to a newer edition. Later editions of the NEC do not take effect automatically when NFPA publishes them; the board must give public notice and hold a hearing before it adopts one. That is why Arkansas has often enforced an edition that is one or two cycles behind the newest one. Before the 2026 rule, the state code was the 2020 NEC. An earlier proposal had sought to move to the 2023 edition while keeping parts of the 2020 branch circuit rules, and the 2026 hearing notice proposed moving from the 2020 edition to the 2026 edition and updating the rule to reflect a 2025 act of the legislature.

Why the state amends the code

Every model code is written for the whole country. A state board adopts it with amendments where its members, after public comment, decide that a requirement adds cost without enough benefit in that state, conflicts with another law or needs clarification. Arkansas's amendments have focused on dwelling branch circuits, especially arc-fault and ground-fault protection, and on kitchen receptacle layouts. Contractors, inspectors, manufacturers, home builders and utilities often comment on these issues during the hearing, and the final rule reflects a balance of those views.

For a master, the practical point is that the amendments are as binding as the code itself. An inspector enforces the code as amended. A contractor who installs to the unamended NEC may install more protection than the state requires, which is allowed, while a contractor who assumes an amendment exists when it does not will fail inspection. Owners and specifications may also require more than the state minimum, and a contract can require full NEC compliance without the amendments.

The main Arkansas amendments

The 2026 rule's amendments, as summarized here, adjust arc-fault and ground-fault requirements for dwelling units in several ways. Branch circuits in dwellings rated over 130 volts to ground or between conductors, depending on the wording of the rule, are relieved of the arc-fault and ground-fault requirements that the model code applies to some higher-voltage circuits, except for pools, spas and similar installations under Article 680 and floating buildings under Article 682. Laundry areas are relieved of the ground-fault requirement for all receptacles, except receptacles within six feet of a laundry sink, which keep it. Circuits for refrigerators and microwave ovens are relieved of arc-fault and ground-fault requirements; nuisance tripping that can spoil food or disable an appliance is the reason commonly given for this kind of amendment.

The kitchen island and peninsula amendment sets a receptacle count based on counter area. As summarized from the rule, it calls for one receptacle for the first nine square feet of island or peninsula countertop, one more for each additional 18 square feet, and a receptacle within two feet of the outer end of a peninsula. That approach is close to the receptacle rules in earlier editions and differs from the newer model code, which changed island receptacle requirements. Ouachita Bend prices kitchen work from the plan's counter dimensions, so the count matters to every residential bid.

# Island or peninsula receptacle count under the Arkansas amendment as summarized
# (simplified study aid: assumes any part of an additional 18 sq ft adds one;
#  confirm the rule's wording before relying on it)
import math
def island_receptacles(length_in, depth_in, peninsula=False):
    area = length_in * depth_in / 144
    n = 1
    if area > 9:
        n += math.ceil((area - 9) / 18)
    return area, n, ("plus one within 2 ft of the peninsula end" if peninsula else "")
for L, D, p in [(72, 36, False), (96, 42, False), (120, 30, True)]:
    area, n, note = island_receptacles(L, D, p)
    print(f"{L} x {D} in: {area:.1f} sq ft -> {n} receptacles {note}")

72 x 36 in: 18.0 sq ft -> 2 receptacles 
96 x 42 in: 28.0 sq ft -> 3 receptacles 
120 x 30 in: 25.0 sq ft -> 2 receptacles plus one within 2 ft of the peninsula end

The output shows how quickly the count grows on a large island. A six-foot by three-foot island at 18 square feet needs two receptacles under this approach; an eight-foot by three-and-a-half-foot island at 28 square feet needs three; a ten-foot peninsula 30 inches deep, at 25 square feet, needs two plus the receptacle near its end, depending on how the rule treats the end. Because these numbers depend on the exact wording, Tanisha checks each layout against the rule text and the local inspector's reading before finishing a bid.

Local governments and the state code

Cities and counties in Arkansas may adopt rules on materials, construction, installation and inspection as long as they do not conflict with the state standards, under A.C.A. 17-28-305. A city with its own program usually adopts the state electrical code by reference and adds administrative provisions for permits, fees and inspections. Some cities add requirements of their own, such as rules for temporary services or service equipment locations, where their attorneys conclude the rules do not conflict with state law. Utilities also have service requirements, such as meter locations and service entrance details, that are not part of the code but must be met for the utility to connect.

The practical rule is to ask. Before a job in a new city, call the inspection office and ask which code edition and amendments it enforces, whether it has local requirements and how it handles plan review. The answer is usually the state code. When it is not, or when a city is still enforcing a previous edition during a transition, the inspector's answer and the permit determine what the job must meet.

The exam edition and the job edition

The candidate bulletin names the edition of the NEC that the exam is written to, and that edition does not always match the edition enforced on jobs. The November 2023 bulletin used the 2023 NEC while the state enforced the 2020 edition, and the state has now adopted the 2026 edition. Exam questions are usually written to the model code without state amendments, because the exam tests code knowledge, not Arkansas amendments. A candidate should therefore study the model code in the edition named, answer questions from that book, and save the Arkansas amendments for job work and for any questions that clearly ask about Arkansas.

Specifications, plan review and the amendments

Commercial and public projects often come with specifications written by an engineer who may practice in several states. A specification that says the work shall comply with the latest edition of the NEC, or with all applicable codes, can be read more than one way when the state has adopted an amendment. Some specifications require full compliance with the model code, which makes the amendment irrelevant for that job because the contract requires more than the state minimum. Others defer to the code as adopted. Before bidding, read the codes section of the specification, note any conflict with the Arkansas amendments and send a written question to the engineer or architect during the bid period. The answer becomes part of the contract documents.

Plan review, where a city or the state requires it, is the other place the amendments surface. A plan reviewer reviewing a commercial job in Little Rock will apply the code the city enforces, which is normally the state code as amended. A plan reviewer for a project with a federal or institutional owner may apply that owner's own standards on top of the code. Ouachita Bend's estimators keep a one-page list of the Arkansas amendments taped inside the estimating binder, with a note about how each one affects pricing, so that bids on similar houses do not swing because one estimator assumed full NEC compliance and another assumed the amendments.
