Electrical panel
A electrical panel is equipment in the electrical category. Distribution equipment requiring circuit directories, disconnect identification, and arc flash labelling before energised work.
Also called: panelboard, load center, breaker panel, distribution panel, switchboard.

National Electrical Code
Panel directories, disconnect identification, and available fault current marking.

Required artifacts
| Artifact | What it does |
|---|---|
| Engraved nameplate | A rigid engraved plate identifying equipment, a circuit, or a disconnect, readable for the life of the asset. |
| Arc flash label | A label carrying incident energy, working distance, arc flash boundary and the PPE required for energised work. |
| Inspection tag | An inspection tag is a compliance consumable affixed to equipment that records who serviced it, when, and under what licence. |
| Service label | A service label is a compliance consumable applied directly to equipment recording a test, a certification, or a next-due date. |
Which of these you actually need, and on what cycle, depends on your jurisdiction. We publish that only where we have read the governing clause and can cite it. Where we have not, the page says so rather than guessing.

What it is
An enclosure holding breakers or fuses that distribute power to circuits, with a dead front cover and a circuit schedule. Anything from a domestic consumer unit to a six foot distribution board.
Why it gets inspected
The hazard is arc flash, and the information that protects against it is on the outside of the door. A panel whose upstream protection changed during a refit now carries a label that understates the incident energy while looking authoritative.
What happens on a visit
Thermal scan under load for hot connections, confirm the schedule matches reality, check the dead front is secure and clearances are clear, and verify the arc flash label still matches the current study.
What drives the tag count
Two different artifacts live on the same panel and they are ordered differently. The nameplate is a permanent installation identifier that should still be correct in fifteen years, and the arc flash label carries study output specific to that one piece of equipment. Never order arc flash labels as a generic run - a label showing the wrong incident energy tells an electrician to dress for a hazard that is not present.
What actually gets tagged, and where it goes
A panel accumulates several unrelated artifacts. Identification of the disconnecting means, arc flash warning conveying the result of the incident energy analysis, lockout points for energy control, and the panel schedule itself. They come from different obligations, are updated on different occasions, and are frequently supplied by different people, which is why panels so often carry a mixture of labels of wildly different ages. Field applied markings need durability appropriate to the environment, and the failure indoors is print fade rather than mechanical damage.
What a scan of electrical panels shows
The dangerous property of electrical labelling is that a label cannot communicate its own age. A panel modified four years ago carries markings that look exactly as authoritative as ones applied yesterday. A scan resolves to the panel and shows when each marking was applied and what for, which turns an anonymous laminate into something dated. For an installation modified by a dozen contractors across its life, knowing when a marking was made is often more useful than what it says.
Every artifact here is serialised, so the record survives the tag being replaced. The mechanics are on how inspection records work.
Sizing an order for a fleet of electrical panels
Count panels, then multiply by the artifacts each one actually needs, which is normally three or four rather than one. Arc flash labels are driven by the study rather than by the panel count and are ordered when the study is done or revised. Identification and lockout labelling are ordered against the panel count. Ordering the three together per panel avoids the common outcome where a panel gets its arc flash label years before or after everything else.
Minimum is 100 units and every price is on the page, so a first order can be a test rather than a commitment. Why the minimum is 100, not 2,500.
Inspected on the same visit
Panels and switchgear are labelled in the same exercise, usually against the same arc flash study, and the same programme normally covers the energy control points on guarded machinery. Where the facility handles corrosives, the eyewash stations fall inside the same safety walk. The important ordering point is that arc flash labels are driven by a study rather than by a calendar, so they are ordered when the study is done or revised, while identification and lockout labelling are ordered against equipment count.
Ordering electrical panels: common questions
How many labels does one panel need?
Normally three or four rather than one. Identification of the disconnecting means, arc flash warning, lockout points, and the panel schedule all come from different obligations and are frequently supplied by different people. Ordering them together per panel avoids the common outcome where a panel gets its arc flash label years apart from everything else.
Do you produce the arc flash values?
No. The incident energy analysis is engineering work performed by a qualified engineer, and the values come from that study. We print the label to the required format and bind it to a record so the study date and revision history are reachable from the equipment.
Why does it matter when a label was applied?
Because a label cannot communicate its own age. A panel modified four years ago carries markings that look exactly as authoritative as ones applied yesterday. For an installation modified by many contractors across its life, the date is often more useful than the text.
