The Texas Commission of Licensing and Regulation adopted the 2020 National Electrical Code (NEC) as the electrical code for the state of Texas as of Nov. 2, 2020.
However, in May 2021, the Commission voted to delay the effective date of section 210.8(F) until Jan. 1, 2023, because compliance with that section poses an imminent threat to public health and safety by interfering with the proper functioning of certain types of air conditioning and heating systems.
William Weatherly, TDLR Program Chief and Chief Inspector for Air Conditioning and Refrigeration, said that adding GFCI protection to air conditioning and heat pump equipment that uses DC Inverter technology -- as required by the 2020 NEC -- can cause repeated tripping of the circuit protection, making the systems effectively inoperable.
What does Section 210.8(F) of the 2020 NEC do?
Section 210.8(F) of the 2020 NEC requires that certain outdoor outlets for dwellings supplied by single-phase branch circuits rated 150 volts to ground or less, 50 amperes or less, have ground-fault circuit-interrupter (GFCI) protection. The emergency rules adopted by the Commission would remove this requirement until January 1, 2023.
Why is this change being made?
There have been widespread reports of certain types of air conditioning units connected to a GFCI device not being compatible with the GFCI protection, which causes the GFCI device to trip. This incompatibility poses a substantial risk to the health and safety of all Texans who rely on air conditioning, especially during the summer months.
What does this change mean for electricians and air conditioning and refrigeration contractors?
Beginning May 20, 2021, neither electrical contractors nor air conditioning and refrigeration contractors are required to comply with the requirement of Section 210.8(F) of GFCI protection for certain outdoor outlets until January 1, 2023.
A code-compliant installation, with emphasis on a proper bonding of the equipment to the equipment grounding conductor and to the electrical grounding system, will ensure electrical safety for fault conditions, even when terminated to a normal overcurrent protection device.
More on the 2020 NEC
The 2020 NEC is the "minimum standard" for all electrical work in Texas covered by the Texas Electrical Safety and Licensing Act.
Chapter 1305.201 of the Act gives municipalities the authority to make local amendments to the 2020 NEC; however, any proposal to amend these standards should be done in accordance with NEC 90.4, which stipulates "the authority having jurisdiction may waive specific requirements in this Code or permit alternative methods where it is assured that equivalent objectives can be achieved by establishing and maintaining effective safety."
Any non-exempt electrical work -- other than the exemption listed above -- started on or after November 1, 2020 must be installed in accordance with the 2020 NEC.
To clarify: the “start” of electrical work is the day the electrician begins installing electrical materials or equipment within the residential or commercial building structure. Inside the corporate limits of a municipality, the start date is the permit date. Electricians must abide by city permitting requirements and adhere to any state code amendments by the municipality.
As of Nov. 1, 2020, all licensing examinations for Texas electrical licenses are based on the 2020 NEC. Texas electrical licensing exams are available through PSI, the testing vendor selected by TDLR to develop, maintain and administer the examinations.
Licensing candidates should carefully review the Candidate Information Bulletin (CIB) for detailed and helpful information regarding the examinations
