What the Arkansas rule changes
Recent NEC editions expanded GFCI protection to more 240 volt circuits in homes. Arkansas kept the 2026 NEC as its base but wrote its own amendment: AFCI and GFCI protection are not required on dwelling unit circuits over 130 volts, except for the requirements in Articles 680 and 682. Article 680 covers swimming pools, fountains, spas and hot tubs. Article 682 covers natural and artificially made bodies of water. So the relief applies to ordinary 240 volt household loads, not to water equipment.
Worked example: a 240V hot tub in Little Rock
A homeowner in Little Rock buys a 240V MyHotTub Victoria, which needs a GFCI breaker that is not included. The electrician might assume the over 130 volt exception removes the GFCI. It does not: the tub is Article 680 equipment, so 680.44 GFCI protection and the 680.13 disconnect within sight, at least 5 feet from the water, still apply. If the homeowner wants to pull the permit, Little Rock's Article 111 requires a state license or a $35 consultation, proof of ownership and residence, and a competency review with the Electrical Inspections Supervisor before the permit is issued.
Cold plunges
Most cold plunge chillers, including the 450 W Penguin Chillers unit we use for cost math, run on 120 volts, below the 130 volt line, so the exception never comes into play. A plunge with a 240 volt chiller or heater still falls under Article 680 as hydromassage or spa equipment. Either way, plan on GFCI protection. Our cold plunge GFCI guide covers circuit sizing.
Why it matters for cost
A 240 volt GFCI breaker costs more than a standard breaker, and nuisance trips are the most common complaint with plunges and tubs. Arkansas does not let you skip it for water equipment, so budget for the GFCI breaker or a GFCI spa disconnect from the start. Power itself is cheap in Arkansas, at 14.37 cents per kWh in August 2026 per EIA, so a 4 kW heater hour costs about $0.57.

Frequently asked questions
Which NEC edition does Arkansas use?
The Board of Electrical Examiners' rule, 17 CAR 210-601, adopts the 2026 National Electrical Code with Arkansas amendments. NFPA's enforcement map may still show the earlier edition while it updates.
Does Arkansas require GFCI on a 240 volt hot tub?
Yes. The Arkansas rule removes AFCI and GFCI requirements from dwelling unit circuits over 130 volts, but keeps the requirements of Articles 680 and 682. Hot tubs, spas and pools are Article 680 equipment, so their GFCI rules still apply.
Does the exception apply to a cold plunge chiller?
Not to a plunge or chiller wired as spa or hydromassage equipment under Article 680. Most chillers run on 120 volts anyway, which is below the 130 volt line, so GFCI protection applies either way.
What circuits does the Arkansas exception affect?
Dwelling unit circuits over 130 volts outside Articles 680 and 682, for example a 240 volt range, dryer or air conditioner circuit that a newer NEC edition might otherwise require to have GFCI protection.
Can a homeowner pull an electrical permit in Little Rock?
Yes, for a home they own and live in, if they hold a state master or journeyman license or pay a $35 consultation fee. The homeowner shows proof of ownership and residence and consults with the Electrical Inspections Supervisor about the project and their competency.
Is a homeowner license exemption statewide?
Arkansas law allows owners to do some electrical work on their own primary residence, but cities run their own permit and inspection programs. Ask your city before you start.
