George your claim that "The NEC is not the Code" is not true in Texas, and that point is specifically stated in this NEMA release from a couple of years ago.

Here is substantiation:

Code Alert: Texas, 01 June 2005
NEMA > Standards > Field Representative Program > Code Alerts > Code Alert: Texas, 01 June 2005

On Wednesday, June 1, 2005 the Texas Commission of Licensing and Regulation formally adopted the 2005 edition of the National Electrical Code® as the State of Texas’ basic electrical installation code. Enforcement will be effective on July 1, 2005 and this adoption replaces the 2002 edition of the National Electrical Code®, which was the first State of Texas mandated electrical installation code for all classes of occupancies that was first adopted by the Commission in January 2004 and that went into effect on September 1, 2004.

However, even with the 2005 edition of the National Electrical Code® being adopted by the State of Texas as the basic electrical installation code in the state, incorporated cities in the state may amend the edition of the National Electrical Code® adopted by the state. But, for unincorporated areas outside a municipal jurisdiction, the 2005 National Electrical Code® as written will be the electrical installation code. Texas also adopts the International Residential Code (IRC) for all 1&2 Family Dwellings but did not adopt Chapters 33-42 (the electrical provisions chapters) of the IRC and continues to utilize the National Electrical Code® for electrical installations in one and two family dwellings.
