| (B) Add TDLR, Texas Department of Licensing and Regulation,
P.O. Box 12157, Austin, TX 78711 as a promulgating agency; add 2012
TAS, 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 2014 National Electrical
Code shall be amended as follows.
(1) Add the following to Article
310.1 Scope: "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."
