Box 12157, Austin, Texas 78711 as a promulgating agency; add 2012 TAS - effective March 2012, Texas Accessibility Standards as adopted under 16 Texas Administrative Code, Chapter 68 as the referenced standard; and add code sections 102.4, 410.8.2, 410.8.3, 410.8.10, 705.1.2, and 705.1.3 as the referenced code sections."

(j) The 2020 National Electrical Code shall be amended as follows.

(1) Amend Article 310.1 Scope to read as follows: "This article covers general requirements for conductors rated up to and including 2000 volt and their type designations, insulations, markings, mechanical strengths, ampacity ratings, and uses. These requirements do not apply to conductors that form an integral part of equipment, such as motors, motor controllers, and similar equipment, or to conductors specifically provided for elsewhere in this Code. Aluminum and copper-clad aluminum shall not be used for branch circuits in buildings classified as a residential occupancy. Aluminum and copper-clad aluminum conductors, of size number 4 AWG or larger, may be used in branch circuits in buildings classified as occupancies other than residential."

(2) Add new Article 545.14, Testing, to read as follows.

(A) "(A) Dielectric Strength Test. The wiring of each modular house, building, or component shall be subjected to a 1-minute, 900-volt, dielectric strength test (with all switches closed) between live parts (including neutral conductor) and the house, building, or component ground. Alternatively, the test shall be permitted to be performed at 1080 volts for 1 second. This test shall be performed after branch circuits are complete and after luminaires or appliances are installed. Exception: Listed luminaires or appliances shall not be required to withstand the dielectric strength test. Exception: A DC dielectric tester can be used as an alternate to the use of an AC dielectric tester. The applied test voltage for testing with a DC tester shall be 1.414 times the value of the equivalent AC test voltage."

(B) "(B) Continuity and Operational Tests and Polarity Checks. Each modular house, building, or component shall be subjected to all of the following:

(1) An electrical continuity test to ensure that all exposed electrically conductive parts are properly bonded;

(2) An electrical operational test to demonstrate that all equipment, except water heaters and electric furnaces, are connected and in working order;

(3) Electrical polarity checks of permanently wired equipment and receptacle outlets to determine that connections have been properly made."

(3) Remove Section 210.8(F).
