What changed, in one line

Device-type switches went to Article 406 for the 2026 edition, arriving as a new Part III. The general-use snap switch, the dimmer and the electronic control switch are all answered there, and Article 406 changed its name to match. It used to be Receptacles, Cord Connectors, and Attachment Plugs. In the 2026 book it is Wiring Devices, and the switches sit alongside the receptacles under that heading.

Article 404 kept the heavier apparatus. General-use switches of the enclosed disconnect kind, motor-circuit switches, isolating switches, pullout switches, molded-case switches and circuit breakers used as switches all stayed where they were. So Article 404 is still a real article, still about switches, and still written in the same house style. It has stopped answering the question you're most likely to be asked about a switch.

Texas adopted the 2026 edition effective 1 September 2026 under 16 TAC 73.100, so from that date this is the book your paper references. An older copy fails you twice over: on this split, and on everything else that moved.

What the exam asks about the split

Two items in our bank test this directly, and both are written at the top difficulty bands. The first asks which article holds the rating and construction requirements for a wall dimmer or a general-use snap switch in the 2026 edition. The four options are bare article numbers: 406, 404, 408 and 410. The trap line on the 404 option says the thing worth carrying, which is that Article 404 kept the larger switches and lost the device on the wall, the reverse of what most people memorized.

The second asks what Article 404 still covers, and the correct answer names switching devices other than the ones mounted in a wall box, such as motor-circuit and isolating switches. Its distractors are the three plausible histories: that Article 404 still holds the snap switches and dimmers, that it holds panelboards, and that it covers every switch as it always did. Panelboards have been Article 408 since the 2002 edition, when switchboards and panelboards came out of Article 384.

The word switch turns up in only nine of the 500 stems, and those nine sit across four different areas of the bank: installation, grounding and bonding, motor calculations, and administration and definitions. That spread is the real lesson. A switch question on the Texas paper is rarely about a light switch, and knowing which kind of switch you're holding decides which article and sometimes which portion of the exam you are in.

The dividing line is a defined term

Article 100 defines wiring device, and that definition is the boundary. A wiring device is an electrical device with a yoke, or used with flexible cord or cable, that serves either as a connection point for current or as a control device in general distribution and branch circuits. Two hooks, and between them they decide the article.

Read the two halves of 404.1 next and the split stops being a memory exercise. 404.1(A) lists what Article 404 still covers. 404.1(B) lists what it does not, and wiring devices are the second item on that list, with an informational note naming 406.1 as the destination.

Two shortcuts that feel reliable and fail

The first pivots on the word snap. It gets the snap switch right and then breaks, because a dimmer carries no such name and neither does an electronic control switch, and both are wiring devices. The second pivots on physical size, or on whether the thing mounts in a device box. The definition's second hook has nothing to do with a box: a device used with flexible cord or cable is a wiring device too. A switch hanging on a cord satisfies that hook, carries no snap switch label, and never sees a device box, so a size test and a box test both send it to Article 404, which has stopped covering it.

Use the definition every time. Ask whether the thing in the stem sits on a yoke or is fed by a flexible cord. Where it does, the answer lives in Article 406 in this edition, whatever the item calls the device.

The four articles an item will offer you

An item that hands you four article numbers is usually offering the same four, and two of them never moved, which makes them the easiest to strike.

What the stem describesArticleStatus this cycle
A device on a yoke or on a cord: snap switch, dimmer, electronic control switch406Arrived here for 2026, in a new Part III
Motor-circuit, isolating or pullout switch, molded-case switch, circuit breaker used as a switch404Stayed, and the article kept its title
The switch as part of a panel408Unmoved since the 2002 edition
A switch controlling a luminaire, where the real question is the luminaire410Unmoved, and covered on our luminaires page

That fourth row catches people. An item about a clothes closet that mentions a switch is a luminaire item, and it turns on the type of luminaire and its clearance from the defined storage space, which is worked through on luminaires and closets.

A switch can be a disconnect

Here's where the Texas candidate needs both meanings of the word in the same sitting. On the knowledge portion a switch question is usually an article question. On the calculations portion a switch is a rated device and the item is arithmetic.

One of our bank items proposes a 30 ampere general use switch as the disconnecting means for a motor with a table full load current of 27 amperes and asks whether it complies on ampere rating alone. Section 430.110(A) sets the minimum at 115 percent of the full load current, so 27 times 1.15 gives 31.05 amperes and the 30 ampere switch falls short by an ampere. The distractors are the three neighbouring rules: comparing the switch rating with the raw full load current, applying the 125 percent conductor multiplier to get 33.75, and rating the disconnect at 100 percent of the load.

A second item uses a general use switch as the controller for a 2 horsepower stationary motor on 230 volts drawing 8 amperes. Section 430.83(C) permits that for a stationary motor rated 2 horsepower or less and 300 volts or less, provided the switch has an ampere rating of at least twice the motor full load current, which gives 16 amperes. The doubling exists because the switch has to make and break starting current. Mixing that up with the 115 percent disconnect rule is the single commonest way to lose the item, and both sit on disconnecting means.

What is confirmed and what is not

The move, the new article title and the two halves of 404.1 are confirmed against the 2026 text and against independent code-change reviews, including one published by a state licensing authority. We state those as fact.

The internal structure of Part III is a different matter. Published accounts of which section number holds which requirement inside Article 406 disagree with one another, so this page names no section number inside that part and you should carry none into the room either. Read the part heading and the section headings in your own copy during the check below. Where two published sources conflict on a section number, the honest answer is to print the conflict and send you to your own book, because a confident wrong number costs more than a lookup.

If your book says something different from what is here, tell us, and the correction goes up with a date on it.

A one minute check on your book

This check doubles as proof that the book on your bench is the right edition, and it takes under a minute.

  • Turn to Article 406 and read the article title. In the 2026 book it reads Wiring Devices. Where it still reads Receptacles, Cord Connectors, and Attachment Plugs, you're holding the previous edition.
  • Look for a Part III listed under Article 406 and read the heading on that part in your own copy. That's the part the switches arrived in.
  • Read 404.1(A), then 404.1(B), one after the other. Those two lists draw the boundary better than any summary of them.
  • Look up wiring device in Article 100 and read the definition with any examples printed under it. That's the sentence you want in your head on test day.
  • Tab 404.1 itself, and either move your old Article 404 tab or add a second one.

That last point is the one that pays. Nobody under a clock reads an article from its first page. You go to a tab, the tab sits on a requirement in the middle of the article, and from there you never see the scope at all. Everything visible says switches: the article title, the running head, and the requirements either side of your thumb. Putting the tab on 404.1 puts the pointer where your hand lands.

What this costs in minutes and dollars

You get about 2.2 minutes per item on the journeyman knowledge portion, counting all 59 items you sit inside the 130 minutes. Reading a correct article that will never contain your answer spends most of that, and doing it twice in a paper is a mark you paid for with minutes. The published pass rate for that portion in fiscal year 2025 was 24.46 percent, so the margin for spending minutes badly is thin.

The money side is the book and the retake. A journeyman application costs $30 under 16 TAC 73.80(a), renewal is the same figure under subsection (b), and all fees are non-refundable under subsection (e), which includes an application the department rejects on eligibility. The examination fee sits outside that rule entirely and is collected by the department's testing vendor at the amount current when you book, so confirm it on your own admission paperwork. The full table is on fees.

There's a continuing education angle too. 16 TAC 73.25(b)(1) names the code as adopted under the Occupations Code without naming a year, so your four hours follow the adoption automatically. A course delivered after 1 September 2026 and taught entirely on 2023 content is teaching an edition Texas has stopped enforcing, and this split is exactly the sort of change such a course will miss. For the rule stated from the code's seat, with the scope sections walked through, the switches question set carries that version.

Questions people ask

Which article covers a light switch in the 2026 NEC?

Article 406, in a new Part III. The general-use snap switch, the dimmer and the electronic control switch all moved there for the 2026 edition, and Article 406 was retitled Wiring Devices to match. Article 404 kept the heavier apparatus: general-use switches of the enclosed disconnect kind, motor-circuit switches, isolating switches, pullout switches, molded-case switches and circuit breakers used as switches. Texas adopted the 2026 edition effective 1 September 2026, so from that date a Texas paper is written against this arrangement.

How do I tell which article a switch question belongs to?

Use the Article 100 definition of wiring device. It has two hooks: a yoke, or use with flexible cord or cable, on a device serving as a connection point for current or as a control device in general distribution and branch circuits. Where the thing in the stem satisfies either hook, the answer lives in Article 406. Where it has no yoke and sits in its own enclosure, the answer lives in Article 404. Reading 404.1(A) and 404.1(B) one after the other draws the same line in the book itself.

Why does pivoting on the word snap fail?

Because it gets one example right and then breaks. A dimmer carries no snap switch label and neither does an electronic control switch, and both are wiring devices that moved to Article 406. Pivoting on size or on whether the device mounts in a box fails for a different reason: the definition's second hook covers a device used with flexible cord or cable, so a switch hanging on a cord is a wiring device, has no snap switch name, and never sees a device box. Both shortcuts feel reliable on the two or three examples you would think of yourself.

Should I tab Article 404 or Article 406?

Both, and put a tab on 404.1 specifically. Nobody under a clock reads an article from its first page, so you land on a tab in the middle of Article 404 where the title, the running head and every requirement around your thumb say switches, and you never see the scope that redirects you. A tab on 404.1 puts the pointer where your hand lands. Remember that only publisher-supplied tabs are allowed in the exam room, so homemade index flags get turned away at the door.

Does this page name the section numbers inside Article 406 Part III?

No, deliberately. Published accounts of which section number holds which requirement inside that part disagree with one another, so naming one here would hand you a number that might be wrong in the room. The move itself, the new article title and the two halves of 404.1 are confirmed against the 2026 text and against independent code-change reviews, including one from a state licensing authority. For the part's internal numbering, read the part heading and the section headings in your own copy.

Is a motor disconnect switch answered the same way?

No, and on the calculations portion it is arithmetic. Section 430.110(A) sets the minimum ampere rating of a motor disconnecting means at 115 percent of the full load current, so a motor with a table value of 27 amperes needs at least 31.05 amperes and a 30 ampere switch falls short. Section 430.83(C) is separate again, letting a general use switch act as the controller for a stationary motor rated 2 horsepower or less and 300 volts or less where the switch is rated at least twice the full load current.
