Re: Exemption from Texas electrical law
I look at it this way. Most industrial facilities are what the state may call exempt from licensing electricians and such, we do not require licensed plumbers either. But if an outside contractor does work for us they are required to be licensed, as a condition by us for them to work in our facility.
We maintain our standards, our facility to OSHA standards and regulations. OSHA uses the NEC as a guidline for investigating and inspecting, even though they are not all that knowledgable on the NEC wiring methods all that well it seems. But if they found something worth questioning they would probably bring in a reliable source of their own. The industrial facility operates as it's own AHJ basically and quite possibly adopts the NEC anyway for doing installations. It's just that if the state requires licensing, then permits from the county, state or whomever would be required just to move a machine. This kind of thing happens to often within a manufacturing facility and not only would it be a hassle for the facility management, but it would put more undo paperwork and strain on the permit process so now when those doing residential or other work that do require permits, don't have to wait while some manufacturing guy stands in line in front of them with 25 permit requests while he is just waiting for 1.
