Texas adopted the 2026 National Electrical Code on September 1, 2026.
Technically, the state is ready.
The licensing side may be another story.
This is the problem I have been watching as states begin adopting the new Code. The NEC has reorganized limited-energy systems and brought Class 4 fault-managed power into that conversation. But many state licensing laws were written around the systems we already knew: Class 1, Class 2, Class 3, communications, fire alarm and what everyone in the field casually calls “low voltage.”
Texas gives us a particularly good example because it has separate agencies regulating electrical work, security systems and fire alarm.
Each licensing structure makes sense on its own.
The problem appears where they meet.
Texas Specifically Exempts Class 1, 2 and 3
Under Texas Occupations Code §1305.003(a)(12), the state’s electrician-licensing law does not apply to the design, installation, repair or alteration of:
- Class 1 remote-control, signaling and power-limited circuits
- Class 2 circuits
- Class 3 circuits
- Fire-alarm circuits
- Optical-fiber cables
- Communications circuits
- Associated raceways
That is a pretty clear list.
It is also a list that does not include Class 4.
Before the 2026 NEC, that omission probably did not get much attention. Class 4 fault-managed power was new, the market was still developing and most of the field’s familiar limited-energy work fit within the older classifications.
The 2026 NEC now brings these systems together within a reorganized limited-energy framework.
That does not automatically rewrite Texas law.
The NEC may say Class 4 is limited energy. Texas law still says the electrician-license exemption applies to Class 1, Class 2 and Class 3.
That creates the first question:
Is someone installing a Class 4 system in Texas now performing electrical work that requires a TDLR electrical license?
Based on the current statutory language, I would not assume Class 4 is exempt.
I have not found a published Texas Department of Licensing and Regulation interpretation answering that question.
That is not the same as saying TDLR has ruled that an electrical license is required. It means the written exemption and the new technical framework do not clearly line up.
That uncertainty will eventually land on a real project.
Then Security Gets Involved
Texas does not treat security work as ordinary low-voltage work.
The Department of Public Safety regulates alarm-system companies and installers, electronic-access-control companies and installers, alarm monitoring, locksmith activities and other private-security services.
Texas’s definition of an alarm system is broader than some people may expect. It can include:
- Burglar and intrusion detection
- Computer-based access control
- Cameras that record or archive images
- Cameras monitored by security personnel or services
- Equipment controlling access through doors, gates and entrances
DPS has also taken a firm position on alarm prewiring.
If wiring would not exist but for the alarm system, DPS considers it part of the regulated alarm installation. A builder can perform certain prewiring only under specific conditions involving supervision, inspection and certification by a licensed alarm installer who assumes responsibility for the work.
That means the electrical-license exemption never told the whole story.
A Class 2 alarm circuit may be exempt from Texas electrician licensing while still requiring an appropriately licensed DPS company and installer.
The system is electrically exempt, not professionally unregulated.
Fire Alarm Has Its Own Lane
Fire alarm adds another agency.
Texas fire-alarm companies and technicians are regulated by the State Fire Marshal’s Office under the Texas Department of Insurance.
Depending on the work, the company may need an Alarm Certificate of Registration, and the individual may need a credential such as:
- Fire Alarm Planning Superintendent
- Fire Alarm Technician
- Fire Alarm Monitoring Technician
- Residential Fire Alarm Superintendent
- Residential Fire Alarm Technician
Again, the fact that Texas exempts fire-alarm circuits from electrician licensing does not mean anyone can install them.
It means the work is regulated through a different licensing system.
So Texas already has three different answers to the question “Who can install this wire?”
- TDLR regulates electrical contracting and electricians.
- DPS regulates security, burglar alarm, access control and covered video systems.
- The State Fire Marshal regulates fire-alarm firms and technicians.
Then Class 4 walks onto the job.
A Security Project Could Need Two Licensing Systems
Picture a new building using Class 4 fault-managed power to serve cameras, access-control panels, edge devices or other security equipment.
The work could divide like this:
- The Class 4 power distribution may fall outside Texas’s Class 1, 2 and 3 electrical-license exemption.
- The cameras, access controls or alarm devices may still require DPS-licensed companies and installers.
- Any connected fire-alarm scope may require State Fire Marshal credentials.
- The equipment and wiring must comply with the 2026 NEC.
- Local permits, inspections and interpretations may still apply.
Now we have a project where the security contractor may be licensed to install and configure the security equipment but not necessarily the Class 4 power system serving it.
The electrical contractor may be licensed to install the Class 4 power system but not necessarily the regulated security equipment connected to it.
That can create several practical questions:
- Who carries the Class 4 cable?
- Who terminates it?
- Who installs the transmitter and receiver?
- Where does electrical work end and security work begin?
- Who pulls the permit?
- Who takes responsibility for the complete listed system?
- Can one company hold all the required credentials?
- Can the scope be divided without violating the equipment listing or manufacturer’s instructions?
- Who owns testing and commissioning?
- What happens when the inspector and licensing agency view the boundary differently?
These are not academic questions.
They affect estimates, subcontracts, crew assignments, inspections, warranty responsibility and schedule.
The Gate Example Shows How Quickly the Answer Can Change
Texas DPS already provides a useful example with gate operators.
A basic gate operator with a push button, keypad or remote may not require a DPS license when it is not monitored and does not log access.
Connect that same gate to an alarm system or add monitoring and ingress/egress logging, and DPS licensing can apply.
The equipment may look almost identical from the outside.
The licensing answer changes because of what the system does.
Now add Class 4 power.
The licensing analysis may depend on both:
- The system’s security function
- The electrical classification of the circuit supplying it
A card reader can create one licensing requirement. The power architecture behind it can create another.
Calling the whole thing “low voltage” will not answer either question.
The NEC Adoption Did Not Resolve This
Texas adopted the 2026 NEC with one published state modification involving GFCI protection for certain outdoor HVAC equipment.
In the adoption material I reviewed, I did not find a discussion connecting:
- Class 4 fault-managed power
- The Class 1, 2 and 3 exemption in Texas electrical law
- DPS security-system licensing
- Electronic-access-control licensing
- State Fire Marshal fire-alarm licensing
That does not mean the agencies are ignoring the issue. It means I have not found a public interpretation or coordinated rule addressing it yet.
As of September 4, 2026, this appears to be something the industry needs to watch.
What Contractors Should Do Right Now
Until Texas provides clearer direction, I would not assign Class 4 work based only on the phrase “limited energy.”
Before bidding or sending a crew, contractors should determine:
- The actual NEC circuit classification
- The voltage and power available during normal operation
- Whether the work falls within Texas’s written electrical-license exemption
- Whether the system performs a regulated alarm, access-control or video-surveillance function
- Whether fire-alarm licensing is involved
- Whether the installer’s company holds the required license or registration
- Whether the individual performing the work holds the appropriate credential
- What the equipment listing and manufacturer require
- How the local inspector expects the work to be permitted and divided
If more than one licensing system applies, that division should be settled before the work is sold—not during inspection.
What Texas Needs to Answer
The first question belongs with TDLR:
Does Texas Occupations Code §1305.003(a)(12) exempt Class 4 fault-managed power installations from electrician licensing after adoption of the 2026 NEC?
The statute specifically names Classes 1, 2 and 3. If Class 4 is meant to be included, the industry needs to know the legal basis for that interpretation.
The second question belongs with DPS:
When Class 4 wiring supplies an alarm, access-control or video-surveillance system, which portions must be performed by a DPS-licensed company and installer?
The third question is a coordination question:
Can a DPS-licensed security installer perform the Class 4 power work without a TDLR electrical license, or must the project be divided between licensed security and electrical contractors?
The State Fire Marshal may need to answer the same questions when Class 4 becomes part of a fire-alarm or life-safety installation.
This Is Bigger Than Texas
Texas is the example, but the problem is national.
The NEC is advancing faster than many occupational-licensing statutes.
Some states define low-voltage work by voltage. Some use Class 2 and Class 3. Some use power limits. Some regulate the company. Some regulate the individual. Some separate fire alarm, security, access control and communications among different agencies.
The 2026 NEC can give us excellent technical requirements without answering who is legally permitted to perform the work.
That is not the NEC’s job.
But if states adopt the technical rules without reviewing their licensing language, the conflict still ends up in the field.
It will show up in bids.
It will show up in scope gaps.
It will show up when two trades claim the same work—or when neither one believes it owns it.
It will show up at inspection, after the cable is already installed.
Watch the Boundary
Texas has adopted the technical rules.
Now the state needs to clarify how those rules fit its existing licensing structure.
Until then, contractors should not assume that:
- “Limited energy” means exempt from electrician licensing
- A security license covers the Class 4 power system
- An electrical license covers regulated security work
- Work performed for years under the Class 2 exemption remains exempt when the power architecture changes
- The contractor installing the cable is automatically authorized to install everything connected to it
The field needs a clean answer before Class 4 becomes common enough for this to turn into a fight over scope.
The NEC changed the technology and reorganized the rules.
Texas now gives us a chance to watch what happens when the technical code moves forward before the licensing language catches up.
Let’s see how the state resolves it.
