Quick electrical enclosure walkthrough
Before analysing, you need to know where to look. This walkthrough reviews your enclosures one by one, at about forty seconds each, and tells you which ones warrant a full criticality study. Nothing to measure, nothing to dismantle: you open, you look, you answer four questions.
It is not a criticality study. It produces no risk priority number, no A/B/C classification and no protection recommendation. Its purpose is to identify the enclosures that warrant the full study, carried out afterwards failure by failure.
Free, no sign-up. Designed to be done on a phone, standing at the enclosures.
Four questions per enclosure
Nothing to measure, nothing to dismantle. You open the enclosure, you look, you answer.
Its name
The tag on your drawings or the label on the door.
Its area
Chosen from your industry's breakdown, loaded at the start with its criticality.
What stops if it fails
Nothing important, one machine, one line, or the whole site.
What you can see
Nothing to report, light traces, a visible anomaly, or an obvious anomaly.
Two optional additions: one or two photos, which go into the report and save you a second trip; and the enclosure's size, picked in one tap from sixteen market standards — wall box, one door, two doors, several cubicles — with a silhouette drawn to the scale of a 1.70 m figure so you can recognise the right category without reaching for a tape measure. The volume is computed for you and follows you into the full study.
Three piles out
Each enclosure is sorted on two crossed criteria: what it represents for the site — the criticality of its area and the impact of its loss — and what was seen when it was opened.
An obvious anomaly — a hot smell, deformed plastic, a gnawed cable — is on its own enough to put an enclosure in R1, even in a room with no production stake. That is a fire signal, not an availability one.

Walkthrough or full study?
The walkthrough sorts, the study analyses. They answer different questions and take different amounts of time.
| Quick walkthrough | Criticality study | |
|---|---|---|
| Duration | 40 seconds per enclosure | 5 to 10 minutes per enclosure |
| What you enter | 4 pieces of information | 7 operating factors, then each failure rated on 3 criteria |
| Method | Triage by stakes and observation | FMECA, IEC 60812 |
| Result | Three piles: R1, R2, R3 | A/B/C class, RPN per failure, decisions D1 to D4 |
| Fire protection | Not covered | P1, P2 or P3 recommendation per enclosure |
| Who for | A whole estate, never reviewed | The enclosures selected, or a small set |
The two follow on from each other
At the end of the walkthrough, the R1 and R2 enclosures can be carried straight into the criticality study, with their name, their area, their dimensions, their photos and the impact of a failure already filled in. You re-enter nothing. On each one, the six other operating factors remain to be filled in — redundancy, age, environment, load, failure history, safety systems supplied — along with the rating of the failures. Until then, the full study flags these enclosures as provisionally classified, and its report says so explicitly.
Frequently asked questions
How long for sixty enclosures?
About forty minutes, at roughly forty seconds per enclosure, walking time excluded. The walkthrough is designed to be done on a phone, on the move.
Do I need to switch off the power or dismantle anything?
No. You open the door and you look, following your site's safety rules. The four questions need no measurement, no instrument and no work on the installation.
Does the walkthrough give a criticality class?
No, and that is deliberate. Four pieces of information are not enough to found an FMECA classification. The walkthrough sorts enclosures into three piles — study as a priority, to be studied, no warning sign — and stops there. The risk priority number and the A/B/C class come from the full study.
What if I do not know the dimensions?
Nothing: the field is optional. If you do want to fill it in, sixteen market standard sizes are offered, grouped by number of doors, with a silhouette drawn to scale. The volume is computed for you.
Can I resume a walkthrough later?
The survey stays in memory as long as you do not close the tab. Download the report at the end of the pass: it keeps a record of what you saw, and serves as the starting point for the next walkthrough.
