An electrical panel schedule records which circuits a panel supplies, the positions each breaker occupies, and the equipment or areas served. Use the printable PDF, editable spreadsheet, or CSV template to organize that information without treating breaker ratings as measured loads.
This template is a circuit directory, not a panel load calculation. It documents circuit identification and installed-device information; it does not calculate demand, verify feeder capacity, or establish whether another load can be added.
Choose a Printable or Editable Template
The supplied files provide three ways to maintain the same circuit record:
| Format | Best use | Included layout |
|---|---|---|
| Printable PDF | Handwritten entries and a paper directory | Two landscape sheets with panel identification fields and 21 blank circuit records per sheet |
| Editable spreadsheet | Maintaining descriptions, equipment references, and revisions | Panel information fields followed by 42 blank circuit records |
| CSV | Importing circuit records into a spreadsheet or maintenance database | Column headings followed by 42 blank records |
The number of blank records is a document layout choice, not a statement about the panel’s available spaces. Add or remove rows to match the equipment. Enter the actual circuit identifiers rather than assuming that the first blank row represents circuit 1.
The PDF and spreadsheet include a panel header. The CSV repeats the panel ID in each circuit record so that records remain identifiable when combined with another panel’s data. Keep system voltage, source information, and other panel-level details in a companion equipment record if you use CSV alone.
Record Panel Information Before Entering Circuits
Use one directory per panel. Complete the header from equipment markings and current, verified project records.
| Header field | What to record | Appropriate source |
|---|---|---|
| Panel ID | The permanent equipment designation, such as LP-1 | Equipment label and current drawings |
| Location | Building, floor, room, or other stable physical location | Facility equipment records |
| System voltage, phases, and wires | The complete system designation, such as 208Y/120 V, three-phase, four-wire | Equipment markings and verified supply documentation |
| Panel bus rating, A | The marked bus rating—not a sum of branch-breaker ratings | Panel nameplate or equipment documentation |
| Main device or upstream protection | Main-breaker information, or main-lug-only configuration with the upstream protective-device reference | Device markings and current one-line diagram |
| Source panel and circuit | The upstream equipment designation and feeder identifier | Verified one-line diagram and source identification |
| Drawing or evidence reference | Drawing number, equipment record, or verification reference supporting the entries | Controlled project or maintenance records |
| Revision and responsibility | Revision date, preparer, and checker | Document-control record |
Keep the bus rating and main protective-device information in separate fields. They describe different equipment characteristics and should not be substituted for one another.
Do not fill missing ratings from a similar-looking panel or a generic product listing. Where U.S. OSHA general-industry requirements apply, 29 CFR 1910.303(e) addresses manufacturer identification, necessary equipment ratings, and durability of equipment markings.
Fill In Each Circuit Record
Use one record for each breaker or clearly identified circuit grouping. For a multipole breaker, include every associated position in the circuit-position field.
| Circuit field | Entry rule |
|---|---|
| Panel ID | Repeat the panel designation, especially in CSV records. |
| Circuit / position(s) | Copy the equipment’s actual identifiers. List all positions associated with one multipole breaker. |
| Load / served location | Identify the equipment, function, and location specifically enough to distinguish the circuit. |
| Poles | Record the installed breaker’s pole count. Do not infer it from the load name. |
| Phase(s) | Record the verified phase connection, such as A, B, C, or A-B-C. Use “Unknown” when it has not been established. |
| Breaker rating, A | Record the marked ampere rating of the installed breaker. Identify adjustable-trip information separately in the notes. |
| Status | Distinguish assigned circuits, installed spare breakers, empty spaces, and unresolved records. |
| Notes / evidence | Record supporting references, shared-circuit relationships, adjustable-trip details, or unresolved discrepancies. |
For an adjustable-trip breaker, distinguish the frame designation, installed rating plug or sensor information, and documented long-time setting where applicable. A single unlabeled number should not stand in for all of these characteristics.
Write descriptions that identify the destination
“Lighting” or “Outlets” may not distinguish one circuit from another. Use descriptions such as:
- Warehouse W1 — north-aisle lighting
- Maintenance room M104 — west-wall receptacles
- Exhaust fan EF-2 — local disconnect supply
- Packaging line 2 — control cabinet CP-2
Prefer stable room identifiers and equipment tags over an employee’s name or a temporary department assignment.
For U.S. workplaces covered by OSHA general-industry rules, 29 CFR 1910.303(f)(2) requires services, feeders, and branch circuits to be legibly marked at their disconnecting means or overcurrent device to indicate their purpose, unless the purpose is evident from their location and arrangement. Paragraph (f)(3) requires those markings to withstand the environment involved. These requirements support clear identification; they do not establish that this particular template satisfies every locally applicable directory requirement.
Follow the equipment’s numbering and phase arrangement
Do not assume every panel uses odd numbers on the left, even numbers on the right, or the same phase sequence by row. Schneider Electric’s I-Line support documentation, for example, identifies both odd/even and sequential numbering-strip options. Its discussion of single-phase I-Line interiors also illustrates why phase labels must come from the actual equipment configuration rather than a generic template.
Copy the manufacturer’s circuit designations and use the verified equipment diagram or installation record for phase assignments. If the physical panel uses a left/right directory, arrange the printed records to match it without changing circuit identifiers.
Distinguish spare breakers, empty spaces, and unknown circuits
Use explicit status descriptions:
- Assigned: The circuit destination is identified in the record.
- Spare breaker: An installed breaker is confirmed to have no assigned outgoing circuit.
- Space: No branch breaker is installed at the identified position.
- Unknown: The destination, connection, or installed condition has not been confirmed.
A breaker that is switched off is not automatically spare. An empty description is not evidence of an available circuit.
“Space” records a physical condition only. It does not confirm that a particular breaker type, tandem arrangement, pole count, or additional load is permitted. Equipment use remains subject to its listing, labeling, and associated instructions; OSHA states this requirement for listed or labeled equipment in 29 CFR 1910.303(b)(2).
Completed Example: A 12-Position Circuit Directory
The following is a hypothetical documentation example, not a tested installation or a recommended circuit design. All equipment descriptions, ratings, and position assignments are assumed solely to show how to fill out the directory.
Panel header:
| Field | Example entry |
|---|---|
| Panel ID | LP-1 |
| Location | Building A, electrical room E101 |
| System | 208Y/120 V, three-phase, four-wire |
| Panel bus rating | 100 A |
| Main device | 100 A main breaker |
| Source | Distribution panel DP-1, feeder LP-1 |
| Evidence reference | Illustrative drawing EX-01; not a field record |
| Revision | Example revision 01 |
For this example only, positions 1 and 2 connect to phase A; 3 and 4 to B; 5 and 6 to C; 7 and 8 to A; 9 and 10 to B; and 11 and 12 to C.
| Circuit / position(s) | Load / served location | Poles | Phase(s) | Breaker rating, A | Status | Notes |
|---|---|---|---|---|---|---|
| 1; 3; 5 | Exhaust fan EF-1 — disconnect supply | 3 | A-B-C | 20 | Assigned | One three-pole breaker; one circuit record |
| 2 | Warehouse W1 — north-aisle lighting | 1 | A | 15 | Assigned | Specific area identified |
| 4 | Packaging line 2 — control cabinet CP-2 | 1 | B | 15 | Assigned | Equipment tag identifies destination |
| 6 | Maintenance room M104 — west-wall receptacles | 1 | C | 20 | Assigned | Room and wall identified |
| 7; 9 | Heater H-1 — local disconnect supply | 2 | A-B | 20 | Assigned | One two-pole breaker; one circuit record |
| 8 | Warehouse W1 — south-aisle lighting | 1 | A | 15 | Assigned | Distinct from circuit 2 |
| 10 | Spare breaker — no outgoing circuit | 1 | B | 20 | Spare breaker | Unused status assumed confirmed for this example |
| 11 | Empty position — no breaker installed | — | C | — | Space | No load or breaker rating entered |
| 12 | Destination unknown | 1 | C | 20 | Unknown | Do not classify as spare |
The three-pole breaker appears once, with all three positions listed. Its 20 A rating is not entered as 60 A. Likewise, the two-pole breaker is recorded as one 20 A device, not as a 40 A load.
Position 12 remains an unresolved circuit even though its breaker rating is known. The directory preserves that uncertainty instead of converting an incomplete record into an apparent spare.
Keep Circuit Identification Separate From Capacity Calculations
This template does not require a load formula because its primary output is a traceable circuit record. The ampere field describes the breaker, not the equipment’s operating current.
Do not add the branch-breaker ratings and compare that total with the panel bus or main-breaker rating to determine remaining capacity. That comparison does not account for actual loads, phase connections, simultaneous operation, or the calculation rules applicable to the installation.
A separate capacity assessment needs information that this directory does not provide by itself:
| Assessment input | Why it is needed |
|---|---|
| Actual load data | Establishes equipment input ratings, documented design loads, or measured operating demand rather than substituting breaker ratings |
| Voltage and connection | Distinguishes line-to-neutral, line-to-line, and three-phase loads |
| Operating characteristics | Identifies simultaneous operation, continuous operation, motor starting, and other relevant load behavior |
| Applicable calculation basis | Establishes the project’s jurisdiction, adopted code edition, and permitted calculation method |
| Existing equipment and feeder details | Identifies bus, protective-device, conductor, and installation constraints |
| Measurement context, when used | Establishes when readings were taken, which equipment was operating, and whether the observation period represents the intended assessment |
Even a directory with a phase entry on every row does not demonstrate phase balance. Phase assignments identify where circuits connect; they do not establish the current carried by each phase.
Keep any calculated or measured load values in separately labeled fields or a linked load worksheet. Identify each value as a nameplate input, calculation result, measurement, or assumption. Do not place those values in the breaker-rating column.
Print, Export, and Maintain the Directory
printable-panel-directory panel-directory-template editable-panel-directory
Prepare the printed copy
Complete the editable master before printing, then check the preview for clipped descriptions, hidden rows, and separated multipole entries. Include the panel ID and revision on every sheet so detached pages remain identifiable.
Use a layout that fits the equipment’s directory holder or other location accepted for the installation. Select a printing and protection method that remains legible in the actual environment; an ordinary paper printout is not automatically a durable installed marking. OSHA’s durability requirement applies where 29 CFR 1910.303(f)(3) governs the installation.
A blank PDF can be printed for handwritten entries. For a typed directory, complete the spreadsheet and print it or save it as a PDF through the spreadsheet application.
Preserve identifiers in CSV
Treat circuit identifiers as text during import. A multipole identifier such as 1; 3; 5 should remain one field rather than being split into three independent circuit records.
Keep these distinctions intact:
- Blank: No value has been entered.
- Unknown: The value has not been confirmed.
- Not applicable: The field does not apply, such as a breaker rating for an empty space.
- Zero: A numeric value, not a substitute for missing information.
CSV does not preserve page layout, merged cells, or print settings. Retain the spreadsheet or another controlled document as the formatted master, and check imported records before using them to produce a replacement directory.
Control revisions and unresolved entries
When a circuit is added, removed, reassigned, or relabeled, update both the master record and the installed directory. Record the revision and retain the supporting drawing or verification reference.
If existing labels and drawings disagree, identify the discrepancy in the working record rather than choosing one without evidence. Circuit tracing or inspection that requires access to electrical equipment belongs within the facility’s qualified-person procedures; completing this template does not establish that a circuit is isolated or safe to work on.
Before issuing a directory, check that every recorded position matches the equipment, multipole breakers remain grouped, destinations are distinguishable, and unknown circuits have not been relabeled as spares. Confirm the required directory content and placement against the project’s adopted electrical code and local requirements rather than treating the template format as evidence of compliance.
