Panel & Disconnect Nameplates
Engraved panelboard, disconnect, transformer and standby-system plates built to the NEC articles your job is inspected against.
The closeout problem
The gear is in. The plates are on the punch list.
Nameplates are the last line on the job and the first thing an inspector can evaluate without opening anything. They get ordered in a hurry, and the shop that can turn them in two days with a proof is worth keeping in your phone.
Send a panel schedule, a photo of the existing directory, or just type the lines out in an email. A quote comes back within 24 hours and a PDF proof follows before anything is cut.
Incident energy, arc flash boundaries, PPE categories, and available fault current all come out of an engineering study under IEEE 1584. Send us the output and it goes on the plate exactly as written. Every quote and order carries the line: all electrical values supplied by customer; vendor performs no engineering analysis.
Example layout. Wording exactly as you supply it.
Code reference
Which article, and what goes on the plate.
A working reference for the markings that come up on commercial electrical work. Handy when a GC asks why the line item is there.
| Article | What it requires | What we make |
|---|---|---|
| 110.21(B) | Field-applied hazard markings must be permanent and suited to the environment they are installed in. Handwritten markings are not acceptable. | This is the article behind every plate on this page. Engraved two-ply satisfies it; a label maker does not. |
| 110.22(A) | Each disconnecting means must be legibly marked to indicate its purpose. Outside dwellings, the marking must also identify the circuit source feeding it. | Disconnect ID plates — purpose plus the panel or source it is fed from. |
| 110.24 | Service equipment outside dwellings must be field-marked with the maximum available fault current and the date the calculation was performed. | AFC plates. You supply the value and the date — we engrave them. |
| 408.4 | Panelboards and switchboards require circuit identification specific enough to distinguish each circuit, plus marking of the source of supply. | Panelboard nameplates and engraved directory plates. |
| 450.14 | Where a transformer disconnect is remote from the transformer, the transformer must be field-marked with the disconnect location. | Transformer plates giving the remote disconnect location. |
| 700 / 701 / 702 | Emergency, legally required standby, and optional standby systems must be identified at all boxes and enclosures. | Generator, ATS, and emergency system identification plates. |
Summarised as a working reference, not a substitute for the published code. Confirm against the edition your authority having jurisdiction enforces.
Florida adopts the NEC through the Florida Building Code, and the edition in force depends on the cycle your permit was pulled under. Tell us which edition your AHJ is enforcing and we will match the wording.
Products
What we make for electrical work.
Panelboard nameplates
Panel designation, voltage and phase configuration, and the equipment it is fed from — the three things 408.4 wants visible. Typically 2″×4″ or 1.5″×4″, white on black.
Disconnect & service plates
Purpose of the disconnect plus the circuit source, per 110.22(A). Adhesive backed for painted enclosures, or drilled for screws where the surface will not take adhesive.
Available fault current plates
The 110.24 marking, carrying the value and the calculation date your engineer supplied. We format it; we never generate it.
MCC bucket & breaker labels
Bucket designation and load served, sized to the door. Sequenced and bagged by section so installation is straightforward.
Transformer plates
Transformer designation, kVA and voltages, and the remote disconnect location required by 450.14.
Generator, ATS & standby
Identification for emergency and standby sources at boxes and enclosures under Articles 700, 701, and 702.
Worth knowing
The 2026 NEC widens arc-flash marking considerably.
The 2026 edition rewrites 110.16 so the old 1,200 A threshold goes away. Switchboards, switchgear, enclosed panelboards, motor control centers and meter sockets outside dwellings all come into scope, each needing permanent marking with nominal voltage, arc flash boundary, incident energy or PPE category, and the assessment date.
Most states will not adopt it until somewhere between 2027 and 2030, so this is not next quarter's work. It is worth knowing about now, because it means a lot more equipment will eventually need a permanent engraved plate rather than a printed sticker — and because your engineer will need to have done the study before any of it can be produced.
When that work arrives, the values still come from the study. We will engrave them onto durable plates in whatever format your AHJ accepts. We will not produce the numbers.

A panel schedule, a valve list, or a photo of what you are labeling now. Quotes go out within 24 hours, a PDF proof comes back before anything is cut, and plates ship two business days after you approve it.
