Arc flash study expiration is the date your study stops meeting NFPA 70E-2027: five years after it was done, or sooner if the system changed. Enter the month and year of your last study and tick anything that changed since. The checker tells you whether it is current, due soon or overdue.
NFPA 70E-2027 130.5(G): review the arc flash risk assessment at intervals of no more than 5 years, and whenever a major modification or renovation takes place.
How to read your result
The badge gives the date status and any change you ticked overrides it. A change means the study no longer matches the gear, whatever the calendar says.
| Result | What it means | What to do |
|---|---|---|
| Current | More than 12 months until the 5-year review | Note the due date and plan the review into next year's budget |
| Due soon | 12 months or less until the review | Book the update now so field work fits an outage window |
| Overdue | Past the 5-year review date | Treat labels as unverified and get an update quoted this week |
| Update needed now | A ticked change has moved the numbers | Update the affected part of the model and relabel it |
Arc flash study renewal without starting over
Arc flash study renewal rarely means a brand new study. If your model and report are on file, the review verifies the installed equipment, applies the changes, recalculates to IEEE 1584-2018 and replaces labels that moved. A clean renewal is faster and cheaper than the first study, and it resets the 5-year clock.

Frequently asked questions
Question not here? Ask an engineer
How long is an arc flash study good for?
An arc flash study is good for up to five years under NFPA 70E-2027, and only while the system stays the same. A new transformer, a utility change, new equipment or changed protective device settings end its validity early, because the incident energy values no longer describe the gear that is actually installed.
What date does the 5-year clock start from?
The clock starts from the date of the study or of its last documented review, as recorded in the report. If you cannot find that date, treat the study as overdue. We can confirm the date from the report and the labels during a short scope call at no charge.
Does the checker replace an engineering review?
No. The checker applies the review interval and flags common change triggers, but only an engineer comparing the model with the installed equipment can confirm the numbers still hold. Use the result to decide when to act, then ask for an update quote to confirm the scope.
Our labels have no date on them. What now?
Undated labels are a common audit finding, because nobody can prove they are current. Assume the study needs review. We match the labels to a report if one exists, confirm the values, and print new labels that carry the study date, which closes that finding for good.
Is a study from a previous owner still valid?
Not automatically. A study bought by a previous owner is only as good as its data and its date. If it is under five years old and the system has not changed, we can verify and adopt it. Otherwise it needs an update before anyone relies on the labels.
Can you remind us before the next review is due?
Yes. When we complete a study or update, the report records the next review date. Ask for a reminder when you accept the quote and we will contact you ahead of that date, so you can budget the review and book field work around your outage calendar.
