Electrical reference chart
Arc Flash Data Worksheet Chart
Use this worksheet after the calculator result to record incident energy, working distance, boundary, PPE notes, equipment label basis, study date, and qualified-person review.
Quick reference table
An arc flash data worksheet is a calculator-led safety planning screen. It preserves the result and the study assumptions so a qualified person can verify labels, tasks, PPE, and energized-work controls before field use.
Arc flash data record
| Field | Record from result | Verification note |
|---|---|---|
| Equipment case | Bus, panel, MCC, switchgear, or label ID | Match the exact equipment and operating mode |
| Incident energy | cal/cm2 result and working distance | Confirm the study case and label date |
| Boundary | Arc-flash boundary distance | Compare with task location and barricade plan |
| PPE note | PPE category or energy-based selection note | Verify with the electrical safety program |
| Follow-up | Study, label, or task gap | Route to qualified-person and owner review |
Arc flash task-context routing
| Task context | Record on worksheet | Why it changes the review |
|---|---|---|
| Normal operation | Switching or interaction task and enclosure state | The task may use different exposure assumptions than maintenance work |
| Troubleshooting | Voltage exposure, test point, PPE note, instrument rating | Live diagnostic work needs separate shock and arc review |
| Maintenance or repair | De-energized plan, lockout status, verification step | PPE notes do not replace establishing an electrically safe work condition |
| Label mismatch | Equipment ID, label date, available fault-current note | Outdated labels can break the incident-energy basis |
How to use this chart
Start with the study case
Identify the exact equipment, operating mode, label date, and calculator or study result before writing PPE notes.
Keep task context attached
Record the task, work distance, boundary, and whether the work is planned de-energized or energized.
Route qualified review
Use the worksheet to list label, PPE, shock boundary, and work-control items that need qualified-person review.
Formula basis
Worksheet record = incident energy + working distance + arc-flash boundary + equipment label basis + task/PPE notes.
- Incident energy is the calculator or study value tied to the same equipment case.
- Working distance is the distance used for the incident-energy result.
- Arc-flash boundary is the distance recorded for the selected equipment case.
- PPE notes describe the task basis and are not a substitute for a current electrical safety program.
Worked examples
Switchboard label review
Record the equipment ID, calculated incident energy, working distance, boundary, label date, PPE note, and whether the task requires energized-work or shutdown planning.
MCC troubleshooting task note
Keep the bucket ID, door state, test instrument rating, working distance, shock boundary, incident-energy value, and qualified-person reviewer together before the task is planned.
